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 Cause Prioritization Lead to own and improve our cause prioritization process, develop a portfolio of early-stage grants across emerging cause areas, and rapidly respond to promising new opportunities that are unusual for GiveWell, do not fit with our existing grantmaking teams and may require innovative approaches to investigation. As part of our lean research team, you will have an outsized influence on our funding decisions and help us save and improve lives on a global scale. You’ll create and lead ambitious research agendas, answer complex questions, and inform high-impact grantmaking decisions by combining rigorous evidence review, cost-effectiveness modeling, and thoughtful judgment. The Cause Prioritization lead will join GiveWell at Senior Program Officer level. You will build a sub-team within the New Areas team and will report to our New Areas team lead. The role As Cause Prioritization Lead, you will be an intellectual leader of GiveWell’s work in new domains. In this role, you will build and lead a new sub-team within GiveWell's New Areas team. You will be responsible for: Improving our cause prioritization process to identify promising emerging areas for grantmaking; ensuring that process combines evidence, cost-effectiveness modelling and our own judgement, and is continuously responsive to new information and external feedback. Overseeing a portfolio of grant investigations and grant management in each of the highest priority emerging cause areas, and starting to build a research agenda including identifying ways to learn about key uncertainties through the initial grants that we make. Communicating externally about our work and building a network of people across implementers, funders, and academia whose expertise span a broad range of cause areas, to help source new ideas. Managing a team to execute these goals, and supporting the professional development of other team members. Creating a culture that is agile and willing to respond to new and unusual opportunities. Directly investigating more complicated grantmaking opportunities yourself. This could include investigating types of programs that are newer to GiveWell; for example, programs earlier in the product development cycle or programs to support government prioritization and planning. In the course of your work, you might approach questions like these: How can we source new grantmaking opportunities in fields in which we don't have an established presence, and how can we make sure we hear from a range of implementers, not just those we've worked with before? How much uncertainty are we willing to accept before making a grant, which questions do we need to answer before making a grant, and which ones can we deprioritize or answer later? What research we can fund today that could substantially impact our grantmaking five years from now? How should we balance exploring and seeding new, smaller opportunities with funding cost-effective opportunities at scale today? How can we ensure that we identify new funding gaps opened up by changes in other donors' priorities? How can we triangulate empirical evidence against expert opinion on other qualitative features, like organizational track record? How can we estimate the probability that a new health commodity comes to market in low and middle income countries, and on what timeline, at what scale? How can we model the cost-effectiveness of a horizontal program which has benefits across a diffuse set of health outcomes? Team structure Our research department is currently organized into eight teams: Five of the teams (Water, Livelihoods, Nutrition, Malaria, and Vaccines) focus on specific areas of grantmaking. 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. The New Areas team focuses on interventions in domains that are new to GiveWell. The New Areas team is currently a 9-person team within an overall research department of ~80 people, and focuses on interventions in domains that are new to GiveWell. Our work is divided into three main workstreams. Grantmaking in emerging cause areas, as well as the process for and identification of new cause areas for that portfolio, would be the primary responsibility of the Cause Prioritization Lead. Core cause areas: this is the set of cause areas for which the New Areas team devotes a significant amount of time developing subject-matter specific expertise and networks, a thorough research agenda, and a relatively large portfolio of grants across a mix of implementers and interventions. This portfolio currently includes our work on maternal and newborn health, family planning, tuberculosis, HIV and medical oxygen. Emerging cause areas: this is a broader set of cause areas for which the New Areas team is starting to build its expertise, networks and research agenda, and is making some initial grants. As our work in these areas becomes more mature, they could graduate to become a core cause area. In addition to new cause areas, this portfolio may include work on types of intervention that are new to GiveWell which could have applications across our teams: recent examples include market shaping, health systems strengthening and applications of AI to global health. Incubators: we support other organisations to identify potentially cost-effective interventions and create programs that we would be excited to support in the future (e.g., the Clinton Health Access Initiative’s Incubator ). For example, we funded a program to provide diarrhea treatment to children in Nigeria that we co-designed with CHAI through the Incubator program. Some of this work could fall under the remit of the Cause Prioritization Lead where it overlaps with our emerging cause areas. Team values We think our research team has unique qualities: We care deeply 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 The Cause Prioritization lead must 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. You can review our staff bios here for more practical insight on the backgrounds and experience of our current team. 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 unusually curious—you ask lots of questions, and you're willing to interrogate others' work. Your curiosity also extends to your own work, and you aren’t defensive when your research comes under scrutiny. You're a generalist and agile —you are able to get up to speed quickly on new topics and you feel comfortable task-switching. You are comfortable pivoting your focus as we learn new information, and are continuously reassessing promisingness. You're a strong strategic thinker. You find ways to impose structure on a broad and undefined problem (e.g., how should your team prioritise work across a huge range of potential cause areas), you can develop and articulate a vision to your team, and build processes to execute that vision. You're excited by people management. You take other team members' professional development seriously, and can provide a supportive environment whilst also delivering constructive feedback. You're able to quickly hone in on the crux of the argument when assessing other people's work, probing on the most decision-relevant assumptions even in fields where you have limited contextual knowledge. You're entrepreneurial. When you see a gap, you want to fill it, whether that's designing a new program, finding an implementer, or setting up a new kind of funding mechanism. You make bets under uncertainty. You routinely think about and surface the value judgments, background knowledge, and strategic commitments that underlie 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. 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.

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.

Location: Novi Sad, South Bačka, Serbia, EMEA From Fivetran’s founding until now, our mission has remained the same: to make access to data as simple and reliable as electricity. With Fivetran, customer data arrives in their warehouses, canonical and ready to query, with no engineering or maintenance required. We’re proud that more organizations continue to leverage our technology every day to become truly data-driven. About Us Fivetran and dbt Labs are bringing together two industry-leading companies with a shared mission: helping organizations unlock the full value of their data. Together, we’re delivering the data infrastructure layer that helps organizations move, transform, and trust their data — from the moment data moves, through every transformation, to the context teams and AI systems rely on. Fivetran helps organizations automate data movement across the systems, clouds, engines, and tools they rely on. dbt Labs pioneered analytics engineering, helping teams transform data into reliable, governed insights. Together, we support thousands of organizations as they build a trusted foundation for analytics, AI, and better business decisions. As we bring our teams and technology together, we’re building on the strengths of both companies while continuing to deliver the products and experiences our customers know and trust. It’s an exciting time to join us: we’re creating a company with the scale, talent, and technology to help more organizations put their data to work with greater speed, confidence, and impact. ​ During this transition period, you may see references to both Fivetran and dbt Labs throughout our recruiting process as we integrate our teams, systems, and career sites. About the Role Fivetran is building data pipelines to power the modern data stack for thousands of companies. We’re looking for a Senior Software Engineer to join our core team and perform a healthy mix of design and implementation tasks to advance the technical foundation behind the Fivetran product offering. This team is tasked with evolving a high performance extract-load-trans form data integration system that enables our engineering teams to correctly implement hundreds of data connectors with minimal maintenance effort. The role will challenge you to reason about relational semantics, powerful abstractions, data representation, and software performance. You don’t need to be a subject matter expert before you join us (you will be one before you leave!), but you will need to have experience working carefully with a high impact software team — especially in environments where the best option may not be obvious, your decisions have cascading implications, and where you sometimes need to measure twice before you cut once. A successful candidate will be humble enough to collect diverse input and build consensus, will be experienced and confident enough to be decisive when it’s needed, and will be practical enough to build and iterate on the system while it’s in production. We are also looking for expertise and productivity with both modern and legacy software development environments. This is a full-time position based out of our Novi Sad office. Our hybrid work model offers a blend of remote flexibility and in-person collaboration.
