Senior Supplier Integration Engineer

About the role

Tern is a venture-backed software company on a mission to reshape the $127B travel agency industry. We are looking for a Senior Supplier Integration Engineer to join our team.

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

Requirements

• 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 specified problems and driven them to a working outcome without someone managing the steps.
• Reliability instincts: You think in failure modes, retries, idempotency, and observability by default. Turning unreliable, poorly documented external APIs into something dependable is work you've done before.
• AI in your daily workflow: Specific examples of where AI made your work faster or better, with the judgment to question its output rather than ship it wholesale.

Bonus points

• Experience with travel industry APIs: GDS, booking systems, supplier data feeds
• Background at a company where the core work was external API integrations
• Comfortable in Ruby on Rails or a comparable MVC stack

What We Value at Tern

• We deeply understand our users. At every level of the organization, we obsess about understanding those we serve and the industry we operate in.
• We embrace the power of and, and not now. We challenge trade-offs by asking better questions. We break hard problems into small pieces and tackle them with intention. We also know to make the hard call to say "not right now."
• We speak up and move forward. Everyone at Tern has a voice and a responsibility to use it. We invite healthy tension, share dissenting views early, and challenge each other with curiosity, not ego.
• We move fast and sweat the details. Velocity matters and relentless progress beats perfection every time. But speed isn't chaos: we stay aligned, own our outcomes, and care deeply about quality.
• We take the work seriously, but not ourselves. We hire kind, driven people who elevate the room. If you've got a big ego or take yourself too seriously, you won't last.

Why Join Tern?

• Be part of a mission-driven team transforming the travel planning space
• Work with a supportive, curious, and creative team
• Influence and shape our engineering approach from the ground up
• Competitive salary, equity, and benefits package
