This role builds and owns the AI and data systems at the core of Tern's product. You'll set the standard on evals, pipeline reliability, and advisor reporting on a small team where the scope is real and the ownership is yours. If you've been waiting for AI problems worth owning, this is that job. ABOUT TERN Tern is a venture-backed software company on a mission to reshape the $127B travel agency industry by giving power back to the entrepreneurs who built it. Nearly 98% of travel agencies are small businesses. These businesses have been chronically underserved by technology. We're here to change that. Our platform helps travel advisors run more efficient, professional, and profitable operations, giving them the modern infrastructure they need to lead the next chapter of travel. But the impact goes beyond business. Travel advisors help clients move more intentionally through the world. When a traveler works with an advisor, they're more likely to avoid overtouristed hotspots and more likely to spend their dollars in places where they can do real good. That's the kind of travel we want more of. At Tern, we believe in small business. We believe in the power of travel. And we're building the future of both. AI & DATA ENGINEER AI is becoming central to Tern's product, and the quality of those AI features lives or dies on the data behind them. This role sits right at that intersection. You'll be a senior builder on our data team, working closely with our Data / AI Lead, and your north star is making Tern's AI features trustworthy. That's an engineering problem, and you'll solve it by building the systems those features run on, the eval harnesses that tell us whether they're actually good, and the monitoring that catches quality and drift in production. That work rests on a data foundation you'll also own. Tern is the system of record for every advisor and agency on the platform, so our data is one of the most valuable things we have, and it has to do double duty by feeding the AI features that are becoming core to the product, and powering the reporting that advisors and agency owners rely on to run their businesses. You'll own that data end to end, from the pipelines that move it through to the reporting built on top of it, so the AI work always has solid ground to stand on. WHY TERN? Tern is building the platform travel advisors run their entire business on, and we believe the next great aggregator in travel gets built right now, on AI. The window to win this market is open, and we intend to take it. With capital and real momentum behind us, we're growing the engineering team this summer to put fuel behind what's already working. This role owns a real part of how Tern works, the kind of work the rest of the team depends on. We hire engineers with high agency and the trust to execute independently, set direction through their work, and lift the standard of everyone around them. We hire for proven execution, so we want to see specific evidence of what you've shipped and the impact it had, in your resume and in the room. ENGINEERING STANDARDS 1. Ship regularly. Every engineering pair ships a working, tested feature every week. Fast and good are not in tension. Testing is part of the build. 2. We own our code and how users experience it. We watch what we ship in production, stay close to support, monitoring, and user feedback, and own our fixes end to end. 3. We make the people around us faster and better, through code and design reviews that teach, through clear written work, and by unblocking our colleagues quickly. 4. Every team is an AI team. We use AI fluently in daily work, from design review to test generation to debugging. We run Claude Code with a deep library of custom skills and agents, unlimited token usage, and we're actively building agentic and MCP-based tooling on top of our own systems. This is how we move fast and build well. OUR STACK Tern is a Ruby on Rails application with a Ho
