Senior Mobile Engineer

Mobile is one of the most visible bets we're making, and you'd own it. There's no existing travel advisor app to maintain. You would have an immense amount of influence on the patterns and priorities. You’ll iterate on how mobile works at Tern, ship in front of every advisors every single week, and watch the team build on what the foundation you set. If you want a surface that's truly yours at a company moving this fast, this is it. 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 MOBILE ENGINEER Advisors run their business on Tern. Right now they do it from a laptop, the next chapter is in their pocket. An advisor mobile app that lets them check a booking, message a client, and keep a trip moving from wherever they are is the future. We want it in advisors’ hands this year. This is a build-from-the-ground role. You'll own the mobile app end to end. The native shell, the native functionality, the embedded web views where they make sense, and the Rails APIs underneath. The "I'm blocked waiting on my endpoint" dynamic doesn't work here. The person who owns the screen owns the API behind it. You’ll work with another paired engineer and PM/design partners to build on mobile over time. Part of the job is leaving behind patterns for platform library usage, web views, release, and on-call, so everyone can move fast. You'll ship every week, own what you ship in production, and set the standard for how mobile gets built at Tern. 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 fresh 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. Mobile is a net-new surface for our advisor product and you'll define it. 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, AppSignal, Bugsnag, and Canny, 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…
