QA Engineer — Wearables, Mobile & Cloud

About the role

A lean health-technology team is building a wearable platform that turns continuous biometric signals into data trusted by researchers, health systems and enterprise partners. The QA Engineer is based remotely, with Austin preferred, and takes ownership of quality from the wrist to the cloud, tracing failures across devices, mobile SDKs, APIs and cloud services, building automation and leading the push for more reliable releases.

Key responsibilities

• Test the full journey: wearable firmware, Bluetooth pairing and sync, iOS and Android SDKs, cloud processing, APIs and the app.
• Reproduce difficult failures, find root causes in device and server logs and deliver fixes or clear engineering handoffs.
• Build automated SDK, API and app tests into CI.
• Own bug triage and release gates, prioritizing customer impact across hardware, mobile and backend teams.
• Test real-world conditions such as overnight wear, workouts, low battery, weak signal, offline use and OS updates.

Required profile

• Substantial QA or test-engineering experience, typically 5+ years, including at least two years owning quality at a startup shipping hardware and software.
• Hands-on Bluetooth/BLE and mobile-device testing, with examples of releases owned and reliability improved.
• Sustained, explainable work history with clear personal ownership of shipped work.
• Wearables, biometrics, health technology, IoT, firmware testing and data-pipeline experience are especially relevant; strong experience with other connected products is welcome.

Required skills

• Coding in Python or JavaScript/TypeScript; ability to read and fix Swift, Kotlin or Go.
• Experience building automated test suites.
• Exposure to native mobile and cloud systems; the environment uses Go, Swift, Kotlin, AWS/S3, Firebase Crashlytics and Mixpanel.
• Practical use of AI coding or testing tools, with a clear approach to checking their output.

What we offer

• Annual base pay of $130,000 to $155,000, plus equity and benefits.
• A player-coach role close to the code, devices and decisions.
