Senior Supplier Integration Engineer

Responsibilities

• Own supplier integrations from design through production, including the realities of third-party APIs: undocumented behavior, rate limits, inconsistent data, and partners who change things without warning
• Ship working, tested integration features every week, broken into the smallest shippable pieces
• Contribute to the abstractions, tooling, and AI-assisted workflows that make each new integration faster than the last
• Watch your integrations in production and catch failures before advisors do
• Make the engineers around you better through code reviews that teach and context shared early
• WHAT YOU HAVE
• Integration ownership: Track record of personally shipping and owning integrations with external systems and third-party APIs. Real stories about what broke, how you found it, and how you fixed it for good.
• High agency: You've taken ambiguous, under, specifie

Additional Information

Every integration we ship puts more of the travel industry inside a single platform. Every one that runs reliably earns an advisor's trust in a way no feature can. If you want to own the build, ship every week, and win this $1.6T industry, we want to talk. 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. SENIOR SUPPLIER INTEGRATION ENGINEER Tern's growth runs through bookable inventory. Every supplier integration we add expands what advisors can book without leaving the app and every integration that runs reliably earns their trust. We're staffing the integrations squad to move fast on cruise, lodging, and insurance partners, and this role is a core builder on that team. You'll own integrations end to end, from the first API conversation through production monitoring, working alongside our integration lead. This isn't about following a spec. You'll take an underdocumented API and turn it into something Tern can depend on: reliable, observable, and ready for advisors to book through. This is a player role on a small, focused squad. You'll ship every week, own your work in production, and contribute to the patterns and tooling that make the next integration faster. 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 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. We own our code and how users experience it. We watch what we ship in production, stay close to support, AppSignal, Bugsnag, and Canny, and own our fixes end to end. 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. 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 Hotwire front end, backed by a Postgres database and hosted on Heroku, though we are migrating to Google Cloud Platform. Our data flows through to BigQuery, where we build reporting in Hex. Claude Code, with our own library of custom skills and agents, is part of daily development. You don't need to have used every piece, but you should be fluent enough to be productive quickly and excited to work this way.
