## About the role

When a kid picks up a Tin Can, the call has to work the first time, every time — whether that’s a call to Grandma or a call to 911. That promise is only as good as our ability to prove it holds before a release goes out. We’re looking for a Senior Software Engineer, Test to own that proof: the automated testing that verifies every call path works, on every change, before it reaches a kid’s phone.

## What they're looking for

- 5+ years in software engineering, with deep experience in test automation for production systems where a failure is something a customer feels immediately
- You’ve built end-to-end suites engineers actually trust — fast, deterministic, wired into CI, and rare enough to be believed when they go red
- Comfortable in the guts of a distributed system, you can follow a request across services, read the telemetry, and write a test that proves behavior rather than restating the code
- Fluency using AI as a multiplier across diagnosis, analysis, and testing, this is how we work, not a nice-to-have
- A clear communicator who writes things down, because a test suite nobody understands is a test suite nobody maintains
- Hands-on and scrappy, you’ll build the harness, the fixtures, and the CI plumbing yourself, and you’d rather automate a test than run it twice
