About the role

Architect and break down ambiguous product problems into concrete, well-scoped tasks for agents to execute and ship full-stack features, owning work from design through production release.
Design and operate complex agent orchestration systems that ship real product features.
Design APIs and data models that are clean, consistent, and built to last, not just fast to write.
Contribute to our AI-first engineering culture, share patterns, document what works, and help the team level up on how we build with AI.
Use AI tools fluently - Claude Code, Augment, or equivalent- to compress implementation time, then critically review everything that comes out of them.
Collaborate closely with Product and Design to identify gaps in specs, surface edge cases early, and push back when something isn't ready to ship.
Set the quality bar: well-structured, maintainable code; conduct thorough code reviews; maintain adequate test coverage; and catch bugs introduced by AI before they reach production.

5+ years of professional development using Java and/or JavaScript with a meaningful track record of shipping production systems.
Strong backend fundamentals: API design, data modeling, SQL, service reliability, and debugging production issues.
Demonstrated daily use of AI coding tools (Claude Code, Codex, Cursort or equivalent) in a production engineering workflow.
Ability to critically evaluate AI-generated code: catch logic errors, identify security issues, assess maintainability, and own what gets merged regardless of how it was written.
Strong system design instincts: you think about tradeoffs, edge cases, and what happens when things scale or fail.
Clear communicator: you can articulate why you made a technical choice, flag when a spec has holes, and disagree constructively.
Interest in Elixir or functional programming languages as we expand our stack.
Experience building B2B SaaS products, ideally with complex multi-tenant data models or transactional workflows.
Experience on small, high-output teams where you've had to make architectural calls without a committee.
Frontend experience, particularly with Angular or modern JS frameworks, enough to own a feature end-to-end.
Background in the travel, hospitality, or experiences industry.
