About the Role

What we are looking for:

A Senior Quality Engineer who is a senior software engineer in test who helps the whole engineering organization ship higher-quality software. You build the testing frameworks, tooling, and fast, reliable test feedback that engineers rely on, and you work across our Elixir, TypeScript, and Python codebases to get good testing practices adopted.

This is an enablement role, not a gatekeeping one. You won't test everything yourself; you'll design the systems, set the patterns, and coach the practices that let engineers own quality with confidence. Success looks like teams that ship reliably and independently because the tools and workflows you've built make the right approach the straightforward one.

You'll work hands-on as an engineer — composing testing solutions from in-house and third-party frameworks, hardening CI/CD quality gates, writing production-quality code, and documenting the patterns and playbooks others rely on — while partnering with our Quality Engineering Lead to execute and evolve our automated testing strategy.



You'll participate in engineering reviews focused on testability, reliability, observability, and maintainability, and mature our test automation in line with current industry practice.

AI and agentic coding are core to how we work — we use them across framework development, test debugging, and test authoring — and you'll be expected to work this way.

You might be a good fit if:
- You have 5+ years in software engineering, with significant time as a Software Engineer in Test or Quality Engineer building systems that improve product quality.
- You have strong software engineering fundamentals and write production-quality code in at least one of Python, TypeScript, or Elixir.
- You've designed and implemented automated testing across unit, integration, API, and end-to-end layers, composing solutions from both in-house and third-party frameworks.
- You've built test automation frameworks, test harnes
