Senior QA Engineer - intent

In short

If you're a Senior QA Engineer who's tested apps that talk to physical devices, and you know that "reproduce on my phone" doesn't end the conversation, we want to talk. You'd join us on a freelance, time & material basis : you're paid for the hours you actually work on real client projects. The first three months are about figuring out if we're a good match. When things work out, and that depends on the work itself, the project pipeline, and business timing, there's a real path to our core team with a permanent contract and full benefits.

Why intent ?

We've been designing and co-creating connected devices since 2008. Wearables, smart audio, health-tech hardware for clients like Oura and BOSE, backed by investors like a16z and Founders Fund. We're 60+ people, fully remote, and AI-native since before LinkedIn influencers discovered the term. Our QA isn't "check the screens": it's a mobile app talking to firmware over BLE, sometimes with a flaky signal, sometimes at the edge of battery, sometimes on a phone that decided to update overnight. The bugs are real, the details matter, and good QA changes whether a product ships well or limps out the door.

Who this role is NOT for

If you like running the same test pass every sprint and closing tickets the moment the build is green, we're probably not your people. We look for QA who ask "why" before "how", challenge specs that don't add up, and dig into firmware logs when something smells off. We're AI-native and we expect you to treat AI as a daily multiplier, not a gimmick. What we expect: ownership of what you touch, straight talk when something is wrong, and the kind of curiosity that makes you actually care about the device, not just the app on top of it.

What you'll do

Compatibility testing: make sure devices, sensors, gateways, protocols, and platforms actually play well together

Functional testing: data collection, storage, processing, real-time monitoring, control, integrations

Performance testing: behavior under different workloads, networks, and physical conditions, finding bottlenecks and latency

Security testing: vulnerabilities in devices, communication protocols, transmission, storage, access, auth

Mentor less experienced testers, raise the bar on QA practices

Take part in requirement discussions and daily calls, flag inconsistencies and open issues early

Share knowledge inside the QA chapter and across the company

Use AI tools as part of your daily workflow, not as a party trick

How we work

Fully remote. We have a pet-friendly office in Warsaw and a coworking space in Gdansk if walls and coffee machines motivate you, but nobody will ask why you're not there. Working hours are flexible: most of the team operates between 10:00 and 18:00 CET, and that's when most meetings happen. Evening calls with US-bas
