Location: San Francisco, CA Workplace: OnSite ABOUT US At LangChain, our mission is to make intelligent agents ubiquitous. We build the foundation for agent engineering in the real world, helping developers move from prototypes to production-ready AI agents that teams can rely on. We began as widely adopted open-source tools and have grown to also offer a platform for building, evaluating, deploying, and operating agents at scale. With $125M raised at Series B from IVP, Sequoia, Benchmark, CapitalG, and Sapphire Ventures, we’re at a stage where we’re continuing to develop new products, growth is accelerating, and all team members have meaningful impact on what we build and how we work together. LangChain is a place where your contributions can shape how this technology shows up in the real world. Today, our platform includes LangSmith (Observability, Evaluation, Deployment, Fleet, and Sandboxes), our open source frameworks (LangChain, LangGraph, and Deep Agents), and the newly launched LangSmith Engine for autonomous agent improvement. We have 100M+ monthly open source downloads, 6,000+ active LangSmith customers, and 5 of the Fortune 10 use LangSmith in production (+ 35% of the Fortune 500 overall), including teams at Klarna, Clay, Coinbase, Workday, Lyft, Cloudflare, Harvey, Rippling, Vanta, LinkedIn, Monday.com, Nvidia, and Bridgewater. ABOUT THE TEAM This team works directly with companies building and running AI agents in production, helping turn ideas and prototypes into systems teams can rely on.

Location: United States + International (Remote) GiveWell’s mission is to help people in need as much as we can by researching the most cost‑effective ways to save and improve lives, sharing our work openly, and directing donations to the programs we believe will do the most good. Our work, which focuses on global health and well-being, is funded by tens of thousands of donors who rely on our research to inform their giving. We’ve grown from directing $1.5 million in 2010 to directing more than $400 million in 2025. We anticipate our total grantmaking is likely to approach or even exceed $1 billion this year, and we are working toward a future that could be several times that scale. Through years of deliberate groundwork, we’ve been growing our research capacity and scope in order to direct substantially more funding to the most impactful opportunities we can find. Summary GiveWell is seeking a Senior Researcher on our Cross-Cutting team to help us make better funding decisions across our entire portfolio. The Cross-Cutting team works on methodological questions, research quality, and big-picture problems that don't sit naturally inside any single program area. Cross-Cutting team’s work has included pressure-testing our work through retrospective evaluations of completed grants ( "lookbacks" ) and scrutinizing grantmaking areas ( "red teaming" ), collecting more on-the-ground quantitative and qualitative information to check what our grantmaking might be missing, looking for ways to use AI to improve our research process, experimenting with new ways to solicit feedback , figuring out how to quantify the “value of information” in our grantmaking, and answering thorny research questions that affect our entire portfolio. As a Senior Cross-Cutting Researcher, you'll shape ambitious research agendas that cut across GiveWell's portfolios and answer complex questions that inform grantmaking decisions across the organization. The researchers on our team combine rigorous evidence review, cost-effectiveness modeling, and thoughtful judgment. We're open to a wide variety of professional development pathways depending on your preferences and our needs. The role You will be joining a small team focused on the methodological and cross-portfolio questions that shape how GiveWell does research. You'll sift through the countless questions we could try to answer, hone in on those that matter most, and partner with grantmaking teams (Malaria, Water, Nutrition, Vaccines, Livelihoods, New Areas) to pressure-test and extend their work. You'll also communicate externally about your work and mentor and advise other researchers on the team. You will shape a research agenda that brings rigor and creativity to the thorniest questions GiveWell faces across its grantmaking. Your work will combine empirical evidence review and critical synthesis, cost-effectiveness modeling, discussions with subject matter experts, understanding of the broader context, and your own judgment. In the course of your work, you might approach questions like: Are our grants actually achieving what we predicted? How do we know, and how can we improve our decisions over time? How do we systematically incorporate field insights, monitoring data, and external feedback into our work? How do we design M&E systems that tell us whether grants are working, not just whether grantees are reporting what we asked for? How can we use AI tools to speed up or increase the quality of our work? How should we model spillover effects? Do health programs affect income, and vice versa? Are we consistent in how we handle this across program areas? How should we set our cost-effectiveness bar over time when funding and spending vary unpredictably year to year? How should we value averting a death versus improving health outcomes versus increasing income? (Our "moral weights" problem) Where are the systematic risks in our research (i.e., the areas where if we're wrong, we're making big mistakes in how we allocate funding)? Team structure Our research department is currently organized into eight teams, including Cross-Cutting: Five of the teams (Water, Livelihoods, Nutrition, Malaria, and Vaccines) focus on specific areas of grantmaking. The New Areas team focuses on interventions in domains that are new to GiveWell. The Commons team provides generalized research support to each of the other teams, including landscaping research, vetting, and publishing. The Cross-Cutting team works closely with other grantmaking teams. Projects typically involve partnering with a team to pressure-test or extend their work, or running methodological projects that set standards across the department. Team values We think our research team has unique qualities: We care deeply and centrally about finding and sharing truth. Truth-seeking is one of our core values . We post our mistakes and we prize our team members who keep our culture of free-flowing feedback strong. We are independent. We focus 100% on finding the most cost-effective opportunities to save and improve lives. Our researchers assist in communicating our research findings to the public and our donors, and on occasion we provide tailored advice to ultra-high-net-worth donors who want to rely on our expertise to direct their giving—but we never ask our researchers to trade off against honesty, or to hide their real beliefs. We don’t waste time. Once it’s clear that a particular research question is unlikely to change our bottom-line funding recommendation, we drop it as quickly as possible. We encourage our research staff to constantly re-evaluate their portfolios and only work on the highest-priority questions. Lean research team = huge personal impact. In 2026, our research team of ~80 people is directing close to 1 billion dollars and we expect grantmaking dollars per research team member to increase in the future. We work well together. Our research team is lean because we’re able to attract top-tier people, all of whom complete skills-based assessments before joining our staff. We maintain a high-performing, collegial culture and pay our staff accordingly. About you Senior Cross-Cutting Researchers typically have quantitatively oriented advanced degrees and substantial relevant experience using empirical tools to make rigorous, evidence-based decisions in the real world. Practically, our senior research staff typically has 5-10 years of post-grad work experience prior to joining GiveWell. We're happy to consider applicants who do not have advanced degrees, but we'll look for a commensurate amount of relevant experience. We expect that people with the soft qualities below will be the most successful and happy on our team. This isn’t a full list, but hopefully it conveys the gist of our team’s professional personality: GiveWell’s mission and methods are personally energizing—you like our approach to research and you find personal meaning in our story of impact. You’re abnormally curious—you ask lots of questions, and you’re willing to interrogate others’ work. Your curiosity also extends to your own work—you aren’t defensive when your research comes under scrutiny. You routinely think about and surface the value judgments, background knowledge, and strategic commitments that undergird your work. You understand the potential effects of mistaken mental models, so you strive to improve yours and your team’s. You dislike it when people express strong confidence in views that don’t seem to rely on commensurate evidence. You carefully and legibly communicate about your confidence levels. You appreciate the value of an excellent reputation and strong relationships. You can moderate your directness and intensity when you’re communicating with external folks. You love a gnarly problem . You figure out the most important questions to answer, go deep on the details where they matter (and move on where they don’t), and reassess your mental models based on what you’ve learned. You constantly assess whether you and the team are working on the most important things. Senior Cross-Cutting Researcher vs. other Senior Researcher roles We're hiring Senior Researchers for both our Cross-Cutting team and our grantmaking teams. If you're energized by variety and methodological questions that span multiple program areas, Cross-Cutting may be a better fit. If you're excited to develop deep expertise in a specific program area and eventually own a grantmaking portfolio, our grantmaking-team-specific Senior Researcher roles (e.g., Senior Malaria Researcher or Senior Livelihoods Researcher) may be a better fit. Not sure? Apply to whichever sounds more appealing—we'll help you figure out the right fit during the process, and we're open to moving candidates between tracks. The details Compensation: We set salaries using a location-based tier system. Our pay for this role: NYC or the San Francisco Bay Area: $308,000. All other U.S. locations: $280,000 International: Similar to the “all other U.S. locations” salary, based on historical exchange rates and delivered in locally-denominated currency. We can share a precise figure upon request after the first work trial stage. Benefits: Our benefits include: Fully funded health, dental, vision, and life insurance (we cover 100% of premiums within the US for you and any dependents) Four weeks of paid time off per year 16 weeks of fully paid parental leave Ergonomic home workstations or coworking space memberships Automatic contribution equal to 5% of your gross salary into your 403(b) retirement plan (for U.S. based staff) Countries we can hire from: GiveWell is a remote-first organization. However, for the time being, we can only hire within a select number of countries (US, UK, Canada, Switzerland, and Germany). To be considered for a role with GiveWell, you need to already be based in one of those countries or be willing to move to one of them. We expect to expand the list of locations where we can hire over the course of 2027, and our job descriptions always reflect the current status — so we'd encourage you to check back and apply again for a role you're eligible for. Visa sponsorship: The US is the only country where visa sponsorship is possible for a number of roles, and it's assessed on a case by case basis. For all other countries, you need to already have work authorization, we cannot sponsor visas. Why we work this way: Focusing on countries where we already have tested onboarding processes lets us move candidates through hiring faster and with fewer surprises. Every additional country brings its own labor laws, EOR requirements, and new processes to work through, which slows things down for hiring teams and new colleagues alike. Concentrating our footprint keeps the experience consistent and supports GiveWell’s wider absorption capacity goals. Flexibility: We support and encourage flexible working, including flexible hours, working remotely, and working from the office when you choose. The majority of our staff, including senior management, work flexibly in one way or another. Travel: Research team members are sometimes required to attend international site visits and conferences (on average 1-2 per year), with additional travel for those interested in traveling more. Additionally, we strongly encourage staff members to attend quarterly whole-org and department retreats to bond with other team members and complete in-person work. We'll discuss travel obligations in more detail during late stages of the hiring process, and we’ll accommodate staff who have conflicting family or other obligations. Start date: We’d like a candidate to start as soon as possible after receiving an offer, but we’ll offer flexibility for candidates whose personal or professional circumstances require them to moderately delay their start date. Miscellaneous details: Please note that our hiring process consists of the same work trials for the following roles: Researcher, Senior Researcher, Senior Cross-Cutting Researcher, Senior Livelihoods Researcher, Senior Malaria Researcher, Senior New Areas Researcher, Senior Nutrition Researcher, Senior Vaccination Researcher, and Senior Water Researcher. If, within the last year, you applied and were rejected for one of these roles, you should hold off on applying to the other roles, unless explicitly asked to do so by a member of our team. If you're interested in all of these roles, please just apply once and note in your application that you'd like to be considered for the other roles, too. After application review, our hiring process consists of a short application exercise and up to 15 hours of compensated work trials. You can see more details about our hiring process on our FAQs page ! We devote significant staff capacity to initial application review, and we respond to all applications as quickly as possible. We’re aiming to hire four to six full-time Senior Researchers. We have a strong preference for full-time applicants, but we’ll consider applications for part-time work. We aren’t interested in reviewing applications for contract or project-based work at this time. If we settle on an application deadline, we’ll write it in bold here. If you’re on our website job posting and don’t see a deadline, there is no deadline. If you’re reading this on an external job board and don’t see a deadline, you should double-check on our website . You don't need to submit a cover letter—we rely mainly on your resume and answers to the application questions below when we're making early decisions. About GiveWell GiveWell is dedicated to finding and evaluating highly cost-effective global health and development opportunities, and we publish all the work, reasoning, and uncertainties behind our funding decisions. Our giving funds enable donors to contribute to the most impactful and cost-effective programs our researchers identify. GiveWell is one of the world’s largest private funders of global development efforts. Trusted annually by tens of thousands of donors, GiveWell searches for highly cost-effective programs that save or improve lives the most. Since 2007, more than 150,000 donors have given over $2.6 billion through GiveWell to the most promising programs its research has identified, which we estimate will save more than 340,000 lives . GiveWell is most well-known for recommending a small number of Top Charities , which currently support seasonal malaria chemoprevention , insecticide-treated nets , vaccine incentivization , and vitamin A supplementation . However, most of our research capacity and grantmaking is devoted to cost-effective opportunities outside of those programs . GiveWell grants have: Helped governments navigate changes to the funding landscape and implement high-impact health programs, like HIV/syphilis screening and treatment for pregnant people in Zambia and Cameroon. Sought to scope and scale promising interventions that don’t have clear existing implementers. We are supporting the Clinton Health Access Initiative’s Incubator to identify potentially cost-effective interventions and create programs that we would be excited to support in the future. For example, we funded a program to prevent tuberculosis among young children in Uttar Pradesh and Bihar, India, that we co-designed with CHAI through the Incubator program. Provided funding to ensure that programs that recently faced foreign aid funding cuts could continue, like healthcare support and malnutrition treatment in northern Cameroon. Funded program delivery alongside strengthened monitoring and evaluation, as in our grants to support treatment of clubfoot and to evaluate the program . Tested our assumptions and refined our understanding through further research and data collection, including improved estimates of disease burden and studies on the effect of water chlorination on mortality and the impact of a tree-planting program on farmers’ income . We make our reasoning public and transparent so others can challenge it (sometimes we even pay people to point out our errors ). We go to unusual lengths to check our assumptions and assess our impact, including funding research to address our uncertainties and gathering independent monitoring and evaluation data about the programs we support. We change our minds when the evidence demands it. For more about GiveWell, listen to Ezra Klein’s recent interview with GiveWell’s co-founder and CEO Elie Hassenfeld. Additional information We don’t want to miss candidates that could do great things at GiveWell. Practically, that means a GiveWell staff member reviews every application carefully, considering the whole picture of your background and potential. If you’re on the fence about applying because you meet some but not 100% of our preferred qualifications (some studies suggest this hesitation is especially common for women and people of color), we encourage you to apply anyway. GiveWell is an Equal Employment Opportunity employer by choice. At minimum, this means that we comply with all federal, state, and local EEO and employment laws. Beyond the requirements of those laws, we value our team’s diversity in all respects, and we desire to maintain a work environment free of harassment or discrimination—we want our team members to thrive at GiveWell. If you need assistance or an accommodation due to a disability, contact us at careers@givewell.org. We will consider employment for qualified applicants with arrest and conviction records. By submitting an application, you acknowledge that you have read and consent to GiveWell's Privacy Statement for Applicants . By completing an application exercise, you acknowledge and assent to GiveWell's Work Trial Policy .

Summary GiveWell is seeking a Senior Vaccination Researcher to help us direct tens of millions of dollars annually to the most cost-effective vaccination programs that we can find. You will have an outsized influence on our funding decisions and help us save and improve lives on a global scale. Our vaccination grantmaking is focused on increasing coverage of routine immunization in children under the age of two in areas with high burden of vaccine-preventable disease. This has included supporting targeted outreach and mobile vaccination, demand-side incentives, and support for malaria vaccine rollout. In the future, we may expand into new areas such as campaigns, subsidizing vaccine procurement, supply chain support, surveillance and outbreak response, and R&D for vaccines or vaccine delivery technology. Vaccination is one of our fastest-growing areas, from $12 million in 2024 to $50 million in 2025 and more than $70 million expected in 2026. As a Senior Vaccination Researcher, you’ll create and lead ambitious research agendas related to our portfolios of work and answer complex questions that will inform GiveWell’s grantmaking decisions.

The role You will be joining a small grantmaking team to contribute to our ambitious research agenda on vaccination. You’ll sift through the countless questions we could try to answer, and home in on those that matter most. You’ll also communicate externally about your work and mentor and advise other researchers on the team. You will shape a research agenda that brings rigor and creativity to the thorniest questions the GiveWell vaccination team faces. Your work will combine empirical evidence review and critical synthesis, cost-effectiveness modeling, discussions with subject matter experts, understanding of the broader context, and your own judgment. What you might work on in your first year: How should GiveWell’s portfolio of investments change in response to new technologies and shifts in government or funder resources and priorities? What are the most promising opportunities for grant-making in areas such as surveillance and outbreak response and R&D for vaccines or vaccine delivery technology? How should we prioritize those relative to current core areas? How can we improve our methods for evaluating the impact of programs on vaccination coverage? How can we collect more useful data and combine various sources of information to generate a holistic picture of which programs to expand and which to exit? What are the core differences between GiveWell's cost-effectiveness model and other vaccine cost-effectiveness models and what learnings from the external models should we apply to our model? What is the best design for a study to improve available estimates of the impact of key childhood vaccines on disease-specific mortality or all-cause mortality? The Senior Vaccination Researcher will help shape a major annual grantmaking portfolio, own grant investigations end-to-end (from research question through grant recommendation), and represent GiveWell to external counterparts. You'll have significant latitude to propose new areas of work. Team structure Our research department has over 60 people, and is currently organized into seven teams: Five of the teams (Livelihoods, Malaria, Nutrition, Vaccination, and Water) focus on specific areas of grantmaking. The New Areas team focuses on interventions in domains that are new to GiveWell. The Cross-Cutting team focuses on methodological issues, research quality, and other big-picture concerns that cut across all of our research work. The Commons team provides generalized research support to each of the other teams, including landscaping research, vetting, and publishing. There are currently four people on our vaccination team. Team values We think our research team has unique qualities: We care deeply and centrally about finding and sharing truth. Truth-seeking is one of our core values . We post our mistakes and we prize our team members who keep our culture of free-flowing feedback strong. We are independent. We focus 100% on finding the most cost-effective opportunities to save and improve lives. Our researchers assist in communicating our research findings to the public and our donors, and on occasion we provide tailored advice to ultra-high-net-worth donors who want to rely on our expertise to direct their giving—but we never ask our researchers to trade off against honesty, or to hide their real beliefs. We don’t waste time. Once it’s clear that a particular research question is unlikely to change our bottom-line funding recommendation, we drop it as quickly as possible. We encourage our research staff to constantly re-evaluate their portfolios and only work on the highest-priority questions. Lean research team = huge personal impact. In 2026, our research team of ~80 people is directing close to 1 billion dollars and we expect grantmaking dollars per research team member to increase in the future. We work well together. Our research team is lean because we’re able to attract top-tier people, all of whom complete skills-based assessments before joining our staff. We maintain a high-performing, collegial culture and pay our staff accordingly. About you We expect the Senior Vaccination Researcher to have A quantitatively oriented advanced degree (e.g., in epidemiology, statistics, economics or related fields) Substantial professional experience in the vaccination landscape (broadly defined). This could include experience in epidemiological or health economics modeling, and/or in program implementation or funding. We expect that people with the soft qualities below will be the most successful and happy on our team. This isn’t a full list, but hopefully it conveys the gist of our team’s professional personality: GiveWell’s mission and methods are personally energizing—you like our approach to research and you find personal meaning in our story of impact. You’re abnormally curious—you ask lots of questions, and you’re willing to interrogate others’ work. Your curiosity also extends to your own work—you aren’t defensive when your research comes under scrutiny. You routinely think about and surface the value judgments, background knowledge, and strategic commitments that undergird your work. You understand the potential effects of mistaken mental models, so you strive to improve yours and your team’s. You dislike it when people express strong confidence in views that don’t seem to rely on commensurate evidence. You carefully and legibly communicate about your confidence levels. You appreciate the value of an excellent reputation and strong relationships. You can moderate your directness and intensity when you’re communicating with external folks. You love a gnarly problem . You figure out the most important questions to answer, go deep on the details where they matter (and move on where they don’t), and reassess your mental models based on what you’ve learned. You constantly assess whether you and the team are working on the most important things. If you’re interested in working on GiveWell’s research team but don’t have vaccination expertise, consider applying to our generalist Senior Researcher role. The details Compensation: We set salaries using a location-based tier system. Our pay for this role: NYC or the San Francisco Bay Area: $308,000. All other U.S. locations: $280,000. International: Similar to the “all other U.S. locations” salary, based on historical exchange rates and delivered in locally-denominated currency. We can share a precise figure upon request after the first work trial stage. Benefits: Our benefits include: Fully funded health, dental, vision, and life insurance (we cover 100% of premiums within the US for you and any dependents) Four weeks of paid time off per year, plus a one week organization-wide summer break 16 weeks of fully paid parental leave Ergonomic home workstations or coworking space memberships Automatic contribution equal to 5% of your gross salary into your 403(b) retirement plan (for U.S. based staff) Countries we can hire from: GiveWell is a remote-first organization. However, for the time being, we can only hire within a select number of countries (US, UK, Canada, Switzerland, and Germany). To be considered for a role with GiveWell, you need to already be based in one of those countries or be willing to move to one of them. We expect to expand the list of locations where we can hire over the course of 2027, and our job descriptions always reflect the current status — so we'd encourage you to check back and apply again for a role you're eligible for. Visa sponsorship: The US is the only country where visa sponsorship is possible for a number of roles, and it's assessed on a case by case basis. For all other countries, you need to already have work authorization, we cannot sponsor visas. Why we work this way: Focusing on countries where we already have tested onboarding processes lets us move candidates through hiring faster and with fewer surprises. Every additional country brings its own labor laws, EOR requirements, and new processes to work through, which slows things down for hiring teams and new colleagues alike. Concentrating our footprint keeps the experience consistent and supports GiveWell’s wider absorption capacity goals. Flexibility: We support and encourage flexible working, including flexible hours, working remotely, and working from the office when you choose. The majority of our staff, including senior management, work flexibly in one way or another. Travel: Research team members are sometimes required to attend international site visits and conferences (on average 1-2 per year), with additional travel for those interested in traveling more. Additionally, we strongly encourage staff members to attend whole-org and department retreats 3 times per year to bond with other team members and complete in-person work. We'll discuss travel obligations in more detail during late stages of the hiring process, and we’ll accommodate staff who have conflicting family or other obligations. Start date: We’d like a candidate to start as soon as possible after receiving an offer, but we’ll offer flexibility for candidates whose personal or professional circumstances require them to moderately delay their start date. Miscellaneous details: Please apply to only one Senior Researcher posting. If you have deep expertise in this area, this pod-specific role is the right fit. If not, there's no need to apply here — our generalist Senior Researcher role is designed for strong researchers who don't have a single specialization, and you don't need to apply to both. Applying to the generalist role won't put you at any disadvantage! Please note that our hiring process consists of the same work trials for the following roles: Researcher, Senior Researcher, Senior Cross-Cutting Researcher, Senior Livelihoods Researcher, Senior Malaria Researcher, Senior New Areas Researcher, Senior Nutrition Researcher, Senior Vaccination Researcher, and Senior Water Researcher. If, within the last year, you applied and were rejected for one of these roles, you should hold off on applying to the other roles, unless explicitly asked to do so by a member of our team. If you're interested in all of these roles, please just apply once and note in your application that you'd like to be considered for the other roles, too. After application review, our hiring process consists of a short application exercise and up to 15 hours of compensated work trials. You can see more details about our hiring process on our FAQs page . We devote significant staff capacity to initial application review, and we respond to all applications as quickly as possible. We have a strong preference for full-time applicants, but we’ll consider applications for part-time work. We aren’t interested in reviewing applications for contract or project-based work at this time. If we settle on an application deadline, we’ll write it in bold here. If you’re on our website job posting and don’t see a deadline, there is no deadline. If you’re reading this on an external job board and don’t see a deadline, you should double-check on our website . You don't need to submit a cover letter—we rely mainly on your resume and answers to the application questions below when we're making early decisions. About GiveWell GiveWell is dedicated to finding and evaluating highly cost-effective global health and development opportunities, and we publish all the work, reasoning, and uncertainties behind our funding decisions. Our giving funds enable donors to contribute to the most impactful and cost-effective programs our researchers identify. GiveWell is one of the world’s largest private funders of global development efforts. Trusted annually by tens of thousands of donors, GiveWell searches for highly cost-effective programs that save or improve lives the most. Since 2007, more than 150,000 donors have given over $2.6 billion through GiveWell to the most promising programs its research has identified, which we estimate will save more than 340,000 lives . GiveWell is most well-known for recommending a small number of Top Charities , which currently support seasonal malaria chemoprevention , insecticide-treated nets , vaccine incentivization , and vitamin A supplementation . However, most of our research capacity and grantmaking is devoted to cost-effective opportunities outside of those programs . GiveWell grants have: Helped governments navigate changes to the funding landscape and implement high-impact health programs, like HIV/syphilis screening and treatment for pregnant people in Zambia and Cameroon. Sought to scope and scale promising interventions that don’t have clear existing implementers. We are supporting the Clinton Health Access Initiative’s Incubator to identify potentially cost-effective interventions and create programs that we would be excited to support in the future. For example, we funded a program to prevent tuberculosis among young children in Uttar Pradesh and Bihar, India, that we co-designed with CHAI through the Incubator program. Provided funding to ensure that programs that recently faced foreign aid funding cuts could continue, like healthcare support and malnutrition treatment in northern Cameroon. Funded program delivery alongside strengthened monitoring and evaluation, as in our grants to support treatment of clubfoot and to evaluate the program . Tested our assumptions and refined our understanding through further research and data collection, including improved estimates of disease burden and studies on the effect of water chlorination on mortality and the impact of a tree-planting program on farmers’ income . We make our reasoning public and transparent so others can challenge it (sometimes we even pay people to point out our errors ). We go to unusual lengths to check our assumptions and assess our impact, including funding research to address our uncertainties and gathering independent monitoring and evaluation data about the programs we support. We change our minds when the evidence demands it. For more about GiveWell, listen to Ezra Klein’s recent interview with GiveWell’s co-founder and CEO Elie Hassenfeld. Additional information We don’t want to miss candidates that could do great things at GiveWell. Practically, that means a GiveWell staff member reviews every application carefully, considering the whole picture of your background and potential. If you’re on the fence about applying because you meet some but not 100% of our preferred qualifications (some studies suggest this hesitation is especially common for women and people of color), we encourage you to apply anyway. GiveWell is an Equal Employment Opportunity employer by choice. At minimum, this means that we comply with all federal, state, and local EEO and employment laws.

Location: Canada; United States Workplace: Remote ABOUT DOCKER Docker has been one of the most loved brands in developer tooling, trusted by more than 20 million monthly users and over 20 billion container image pulls. From solo founders to the world's largest companies, developers rely on Docker to build, share, and run their applications across our suite of products including Docker Desktop, Docker Hub, and Docker Scout. We are a globally distributed, remote-first team building the tools that define how software gets built and delivered. As AI agents redefine software development, Docker is at the center of that shift, providing the sandboxed environments, verified images, and secure infrastructure that make autonomous workflows trustworthy by default. _______________________________________________________________________ The DHI Content team builds and maintains Docker Hardened Images: a catalogue of security-hardened system packages, container images and Helm charts designed to be minimal, up to date and safe to use in security-conscious and regulated environments. This is a supply-chain and open-source maintainer role rather than a conventional backend engineering role. You will work across upstream OSS projects, package and image definitions, Helm charts, Kubernetes, integration tests, vulnerability remediation and the controls that prove content is ready to publish. The work is broad by design: customers should be able to select hardened packages and images and, where relevant, deploy them through hardened charts without the pieces drifting apart. We are moving DHI content production towards a machine-first factory. Routine work should begin with a machine-produced change and pass through automated build, test, policy and review controls. Engineers add the most value by handling difficult ecosystems, making security judgements, improving standards and turning repeated human corrections into better tooling. You will use AI-assisted engineering extensively, but remain accountable for the evidence and quality behind every result. As a Senior Supply Chain Security Engineer, you will own substantial content and improvement work from upstream discovery through release and ongoing maintenance. You will be expected to close the loop on customer and security outcomes, not only submit individual definition changes. SUCCESS IN THIS ROLE LOOKS LIKE You will succeed by becoming a trusted end-to-end owner for hardened content. Within your first year, you should have delivered complex new or updated DHI content across packages, images and Helm charts, improved the factory or its quality gates, reduced recurring manual work and raised the capability of the engineers around you. RESPONSIBILITIES - Author and maintain definitions for hardened system packages and container images, including build steps, upstream tracking, multi-architecture support and reproducibility controls. - Adapt and maintain upstream Helm charts so they work correctly with DHI images under non-root, restricted and production-shaped Kubernetes security constraints. - Track upstream releases, semver patterns, monorepos, dependency chains and breaking changes, then make pragmatic decisions about when to update, patch, pin or deviate. - Triage and remediate vulnerabilities across OS packages, application dependencies, images and charts, including VEX and no-upstream-fix cases that require explicit security judgement. - Write and improve Go-based integration tests, validators and policy checks that prove packages, images and charts behave correctly in real environments. - Review human-authored and machine-authored pull requests against DHI standards, distinguish blocking issues from advice and give contributors a clear path forward. - Improve the DHI Factory by converting repeated work, review corrections and escaped defects into automation, tests, validators and reusable authoring patterns. - Help classify work into deterministic, specialist and judgement paths so people spend time where their expertise changes the outcome. - Partner with Product, Security, Support and customer-facing teams to turn demand and incidents into prioritised content and durable improvements. - Engage constructively with upstream maintainers when hardened deployment requirements expose issues or useful improvements. - Participate in the team's paid on-call rotation and drive learning from customer escalations, failed builds and content defects. - Communicate decisions, risks and progress clearly in a remote, async-first environment. QUALIFICATIONS REQUIRED - Strong experience with containers, Linux and Kubernetes in production or production-shaped environments. - Practical experience reading, adapting or maintaining Helm charts and diagnosing how chart templates, values and workload security settings affect deployment behaviour. - Experience maintaining software you did not originate, such as Linux packages, container images, open-source integrations, charts or a comparable downstream distribution. - Strong YAML and configuration-review skills, including care for conventions, consistency and downstream impact across a large catalogue. - Working knowledge of container and Kubernetes security, including non-root execution, UID and GID, capabilities, filesystem restrictions, image layers and multi-architecture builds. - Practical programming ability in Go or a comparable language, sufficient to write and review integration tests, validators and content automation. - Experience tracking upstream releases and reasoning about semver, breaking changes, dependency graphs and reproducible builds. - A maintainer mindset: you catch drift, improve patterns for the next contributor and consider the effect of a change across many downstream consumers. - Familiarity with GitHub-heavy open-source workflows, including pull requests, review, release tracking and upstream contribution. - Comfort using AI-assisted engineering critically while retaining ownership of security assertions, test evidence and release quality. - A strong operational mindset and clear written and spoken communication suited to a remote, async-first company. HELPFUL, BUT NOT REQUIRED - Experience as a maintainer for Alpine, Debian, Fedora, Wolfi, Homebrew or another package ecosystem. - Helm chart authorship or meaningful contribution to an upstream chart. - Experience with SBOMs, VEX, SLSA, Sigstore, cosign, provenance or artefact signing. - Experience with apk, deb, rpm, Go modules, Maven or Gradle, npm, pip, Cargo or other dependency ecosystems. - Experience building automation for package, image or chart creation, validation and release. - Experience with FIPS, FedRAMP, PCI or other regulated and security-conscious environments. WHAT TO EXPECT FIRST 30 DAYS - Build context on the DHI catalogue, its package, image and chart definitions, the DHI Factory and the team's definition of done. - Pair across both image and Helm chart work and ship a useful production change. - Learn the build, test, signing, publishing and vulnerability-remediation workflows. - Take part in reviews and an incident, escalation or failed-build learning session. FIRST 90 DAYS - Own a complex image and chart addition or update from upstream analysis through release. - Resolve a meaningful CVE, dependency or compatibility problem with clear evidence and customer impact in mind. - Improve at least one factory control, integration test, validator or reusable content pattern. - Review across artefact types and help another engineer take on a broader piece of work. ONE YEAR OUTLOOK (FIRST YEAR) - Be a trusted senior owner across hardened packages, images and Helm charts. - Deliver material catalogue growth or quality improvements without increasing human effort linearly with demand. - Reduce recurring manual work by moving a class of changes into a proven automated path. - Improve DHI's security posture, content availability and release reliability for customers. - Raise review quality and grow the team's ability to work across artefact and dependency ecosystems. Docker considers visa sponsorship on a case-by-case basis based on business needs. Compensation & Equity Canada: CA$210,627 – CA$341,690 + equity United States: $154,600 – $250,800 + equity ______________________________________________________________________ POSTING INFORMATION - Open vacancy: This posting is for an existing open role. - AI in hiring: Docker may use AI-assisted tools during our recruiting process. - Interview recordings: Candidates will be invited to opt in to interview recordings to support interviewer calibration and consistent evaluations. Recordings are optional and require explicit consent. ______________________________________________________________________ PERKS & BENEFITS - Remote-first by design – Work from your home, with offices in Seattle and Paris for connection and collaboration. - Flexibility that fits your life – We trust you to manage your schedule while delivering great work. - Time to recharge – Generous PTO, designated quarterly Whaleness Days, and a designated end-of-year Whaleness break. - Home office support – Set up your workspace for comfort and success. - Technology stipend – Equivalent to US$100 net per month to help support your work. - Learning & development – Annual stipend for conferences, courses, certifications, and continued learning. - Parental leave – 16 weeks of paid parental leave after six months of employment. - Equity for all full-time employees – Share in Docker's long-term success as we continue to grow. - Comprehensive benefits – Medical, retirement, and paid holidays vary by country. - Docker swag – Because representing the whale never gets old. Docker is proud to be an equal opportunity employer. We are committed to building a team that reflects a broad range of backgrounds, experiences, and perspectives. We believe diverse teams build better products, make better decisions, and better serve our global community. #LI-REMOTE
