The work is technically varied, and the stakes are real: operators depend on this software to run their businesses.
We're hiring a Senior Full Stack Engineer who works AI-first. We're adapting our engineering practice to match, and we want engineers who are already building this way and are excited to push it further.
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 APIs and data models that are clean, consistent, and built to last, not just fast to write.
Set the quality bar: well-structured, maintainable code; maintain adequate test coverage; 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, Cursor 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.
~ 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.
Frontend experience, particularly with Angular or modern JS frameworks, enough to own a feature end-to-end.
What differentiates engineers now isn't typing speed or memorized syntax; it's the ability to make the right calls on what to build, how to build it, and when it's not ready to ship.
You built it? You own it. You know when to use agents and when to do it yourself.
We want people who ask hard questions, surface problems early, and are willing to push back on a bad spec rather than build it and hope for the best.
Quality as a habit. Peer code reviews, test coverage, and clean APIs are not optional.
