Location: USA - Remote Workplace: Remote 💫 This job description was written by a person   ABOUT US Since 2013, we’ve been building a CRM that gets out of your way and helps your team sell more, faster. Now we’re building AI into every part of it, so Close does the busywork and your team does the selling. No manual data entry, no 10-click workflows. Just communication-first, AI-powered sales software designed to help you succeed and scale. We're bootstrapped and profitable which means we answer to our customers and play by our rules. We're proud of our 130-person, 100% remote team, focused on building Close so that no small, scaling business fails because it can't figure out sales. ABOUT THE ROLE Our GTM org has a lot of questions. Most of the questions we care about can’t be answered by spinning up a cute dashboard. Is branded search creating new customers or capturing demand that already existed? Did the homepage redesign improve conversion, or did our traffic mix change? If we’ve got some wild ideas for our next bet, where should the money go? These kinds of big-picture questions require someone who can interrogate the metric, trace it through the warehouse, understand the business context, and turn it into action. This person will be our first Full Stack Data Analyst dedicated to GTM. You’ll work alongside GTM leadership to make consequential decisions while still staying hands-on in the nitty gritty of all the data. The best part: the way we answer these questions is changing. Effective SQL is just a few tokens away, dashboards can be Claude-ed in minutes, and teammates increasingly expect to find their own answers. You’ll build the semantic layers, context, and guardrails that make self-service possible, even trustworthy, then determine where an analyst’s expertise is indispensable. YOU ARE - An experienced analyst. You have roughly 8 years of hands-on, highly technical analytics experience. Most importantly: you’re backed by the pattern recognition that comes with having seen all sorts of hairy problems. You’re at the point in your career where you can take an ambiguous business question, dive head-first into the data, turn your findings into a decision, and bring everyone else along with you. - A bridge between the technical and the business. You can build a model in dbt, work directly in Snowflake, and translate it into something actionable. You’ll partner closely with our Lead Analytics Engineer but you need to be willing and able to dive in and self-serve. - Fluent in the quirks of GTM data. Attribution, channel definitions, UTMs, bots and broken tracking are known quantities. You don’t need to have been a dedicated GTM Analyst, but you should certainly know your way around this part of the business. - Pushing the boundary of what AI means for analytics. AI is writing your first-draft SQL, analysis, and reporting and you’ve shifted that energy to bringing analysis into the future: building the semantic layers, context, and guardrails that let the team self-serve trustworthy answers. - A trusted cross-functional leader. Teammates across functions and levels listen to you. You immerse yourself in the context of their needs and bridge gaps in understanding. - Fiercely independent and accountable. You welcome a vague ask with aplomb. You’ll scope the problem, find the dependencies, bring in the right people, and drive the work through the analysis, recommendation…all the way to a fix. - More concerned with impact than output. A polished dashboard is useful only when it changes what we do. You prioritize the questions that can materially improve acquisition, conversion, retention, and revenue. YOU WILL - Make our GTM data trustworthy. You’ll define metrics, model the funnel from first touch through paid conversion, and reconcile discrepancies across Snowflake, Segment, Amplitude, GA4, and our ad platforms. - Explain what we’re seeing. Why are trials up while paid conversion isn’t? Why are Snowflake and Amplitude disagreeing? Which channel is driving volume but producing low-quality customers? You’ll dig into the data until we understand what changed and why. - Help decide what to do next. Are we on track to hit our goals? What would another investment in paid media produce? You’ll forecast, model the tradeoffs, and empower leadership to make the best possible decision. - Own the outcome. Whether you uncover something small like broken campaign tracking or you’re focused on moving a major business metric, you’ll bring in the right people and shepherd the team to the data-driven outcome. - Define the next era of Data at Close. You’ll help us move from a queue of reactive requests to a system where an agent spots changes, assembles the context, and gets the right insight to the right person at the right time. BENEFITS - Compensation: Competitive pay plus an organization-wide goal-based bonus - Paid Time Off: ~5 weeks of PTO to start. Plus a 1-week all-company Winter Holiday Break and paid US holidays. You'll earn 2 extra days for every year you're with Close. - 80% Work Option: Work with your manager to choose between a standard 5-day week or a 4-day week at 80% pay - Parental Leave: Paid leave for primary and secondary caregivers - Sabbatical: A 1-month paid sabbatical every 5 years with the team - Healthcare (US residents): Two medical plans with Close covering the majority of your premium, plus Dental, Vision, HSA, FSA, and company-paid Long-Term Disability - 401k (US residents): We match your contributions up to 6%, vested immediately OUR VALUES Build a house you want to live in - Examine long-term thinking and action No BS - Practice transparency and honesty, especially when it’s hard Invest in each other - Build successful relationships with your coworkers and customers Discipline equals freedom - Keep your word to yourself and others Strive for greatness - Constantly challenge yourself and others LEARN MORE Listen to our CEO and Founder, Steli Efti, tell the story of Close’s journey in the $0-30m Blueprint https://www.close.com/blueprint.  Watch our culture video https://www.youtube.com/watch?v=maXKi1GN2MI from our 2023 team retreat in Milan.

Check out a demo https://www.close.com/demo-site! OUR HIRING PROCESS We ask a few role-specific questions as part of our application process. These questions are designed to help us learn more about you from the start, so please answer each one thoughtfully. We see this as an opportunity to get to know you beyond your resume. We use AI tools daily at Close and expect candidates to do the same. In evaluating your application, we aim to get a sense for you - the way you think, how you communicate, the work you've done. Applications that read as fully AI-generated will not be considered. Regardless of fit, you can expect to hear back from our team with an update on the status of your candidacy. If you progress to the interview process, you'll receive a full outline of the role-specific steps in your first touchpoint with us. We do our best to make the hiring process clear and human.

A store keeps serving whether or not the network is up, which means offline capable clients, local state, sync on reconnect, and reconciling what happened while the system was split. Queueing and asynchronous processing, background jobs, and event driven flows. Safe rollout of releases that reach tens of thousands of users. Working directly with product managers and designers to shape what gets built, not just receiving requirements and implementing them. Technical direction and code review for other engineers, including the judgment to say when a design is wrong and the credibility to make that stick. Required Qualifications: 6-8+ years building full-stack products , including time as the senior person on the work. Deep Node.js and TypeScript experience across the full-stack , with production services you designed and still stand behind. Deep understanding of REST API design and microservices. Strong relational database skills, Postgres or MySQL : schema design, indexing, query tuning, transactions, and what actually happens under load. Comfort with non relational stores such as Redis or MongoDB, and with caching and invalidation. Experience with queues and streaming, whether Kinesis, Kafka, RabbitMQ, SQS, BullMQ, or similar, including the failure modes that come with them: ordering, duplicates, replay, and consumer lag. Front- end skill that matches the environment: our team use these screens during a rush, on a terminal or a tablet, with no time to think and no tolerance for a bad interaction. We use Vue. Experience with React or Angular is fine , as long as it includes component architecture, state management, and progressive web apps. Real time interfaces built on websockets, ideally socket.io. Order flow and kitchen display depend on it. Excellent debugging. You can take an unfamiliar production failure and reason your way to root cause instead of guessing. Parts of the existing platform are PHP. Working effectively in unfamiliar code, with AI, is part of this job. Experience deploying services that scale horizontally, tolerate a failed instance or a slow dependency, and automatically add or shed capacity. Comfortable on Linux, and fluent with Git and CI and CD workflows. Excellent written and spoken English. You will be in daily conversation with teams in the United States and Israel, and will often be the person explaining a technical decision to people who did not attend the design discussion. How you work: AI first. You use AI tooling as a core part of how you engineer: mapping an unfamiliar codebase in hours instead of weeks, pressure testing your own designs, moving faster without lowering the bar. You apply it across the whole lifecycle: shaping a design before any code exists, writing and refactoring, reviewing your own work, as well as automated PR reviews. You jump in. Handed a large, complex, unfamiliar repository, your instinct is to open it and start reading. Complexity and sensitivity are reasons to be careful, not reasons to wait for someone else. You build services that stay maintainable. Clear boundaries, readable code, tests that earn their keep, observability that makes production legible. The next engineer should be able to operate what you built without a tour guide. You think about the person on the other side. During a rush, a confusing screen or one extra tap is not a cosmetic problem. It is a slower line and a worse night for the staff. You go the extra mile. You follow a problem to its actual end, including the parts nobody assigned to you. You take pride in the work and you care how it lands for the merchant on the other side of the screen.

Location: Bengaluru, Karnataka, India, APAC 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 As a Staff Full-Stack Engineer on the Cloud Clients team, you’ll own end-to-end delivery across the surfaces where dbt developers do their work: dbt Studio in the browser, the dbt VS Code extension, and the CLI workspace runtime that powers both . You’ll help build dbt’s AI-native developer experience , including agent workflows, diff review, streaming tool calls, charts and rich outputs for conversational analytics, and MCP apps that bring dbt projects directly into tools like Claude and Codex. This is a true full-stack role: you’ll work across Python, TypeScript, React, and Kubernetes , with the expectation that you can take a feature from schema and service design through to the final pixel without a handoff What you’ll do Own parts of the CLI workspace runtime that backs both surfaces, including migrating users off our legacy IDE and enabling asynchronous, background agent runs. Design and build agent-facing experiences: streaming responses, transparent tool calls, diff review, and charting / rich output for conversational analytics. Extend dbt into other developer surfaces — MCP integrations that make dbt projects usable directly from AI clients like Claude and Codex. Lead well-scoped projects end to end: write the plan, partner with design and product, ship in two-week increments, and measure whether it worked. Share oncall and customer support for your surfaces, and mentor engineers earlier in their careers. Skills we are looking for 8+ years building production software, including senior-level ownership of projects that ran for months and involved several people. Deep Python experience plus exposure to TypeScript and React experience — you move across the stack without waiting for a handoff. Built and maintained something other developers depend on: an IDE, an editor extension, a CLI, an SDK, an LSP server, or a data tool. Comfort with the operational side of shipping — APIs, Kubernetes, Postgres, observability — and with being on the hook when something breaks. Strong written communication: you can make a technical argument in a document and bring people along. Worked asynchronously as part of a fully-remote, distributed team Bonus points for Shipped LLM- or agent-powered features to production, with real opinions on evaluation, latency, cost, and where models fall down. Worked with the Language Server Protocol, Monaco, CodeMirror, or other code-editor internals. Hands-on dbt, SQL, or data warehouse experience (Snowflake, Databricks, BigQuery, Redshift). Migrated users off a legacy product surface and decommissioned it without breaking them. Go, Rust, or systems-level performance experience. #LI-HYBRID #LI-JI1 Perks and Benefits 100% employer-paid medical insurance * Generous paid time away from work, including paid vacation or flexible/unlimited vacation depending on role and country, plus paid sick time, inclusive parental leave, paid holidays, including a year-end Global Week of Rest, and volunteer days off.
