The super-magical Wi-Fi landline for kids. No screens, no texting, no strangers — just real conversation with Grandma, besties, and contacts you approve. Plug in, twirl that cord, and time-travel to pure voice fun. Backed by Greylock.
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
More about this role
Tin Can is building a safer, simpler way for kids to connect — without smartphones. We’re creating screen-free, delightful devices and services that let families call the people who matter most, free from the noise of today’s digital world.
We’re building a bold, authentic, nostalgic, and kinda quirky brand that resonates with folks who want something simpler & better for their kids than the tech-infused lives we’re currently living (and who have a sense of humor about it). As we gear up to scale to thousands of families, we’re ready to bring on an engineer to help make it happen.

You’ll own our end-to-end and call-path test suites and the checks that gate a release. The surfaces are real: a staging environment where a change can place an actual SIP call before it merges; a Flutter app on...
