QA Engineer — Wearables, Mobile & Cloud

QA Engineer — Wearables, Mobile & Cloud Remote, United States | Austin preferred | $130,000–$155,000 annual base Own quality from the wrist to the cloud.

Join a lean health-technology team building a wearable platform that turns continuous biometric signals into data researchers, health systems, and enterprise partners can trust. This is a hands-on role with real influence over what ships.

You will trace failures across devices, mobile SDKs, APIs, and cloud services; build automation; fix bugs where you can; and lead the push to make every release more reliable. What You’ll Own 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 the conditions that matter in daily use: overnight wear, workouts, low battery, weak signal, offline use, and OS updates.

What You Bring

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 clear examples of releases you owned and reliability you improved.

Coding in Python or JavaScript/TypeScript; the ability to read and fix Swift, Kotlin, or Go; and experience building automated test suites. Exposure to native mobile and cloud systems. The environment includes Go, Swift, Kotlin, AWS/S3, Firebase Crashlytics, and Mixpanel. You do not need to be an expert in every tool.

Practical use of AI coding or testing tools, with a clear approach to checking their output. A sustained, explainable work history with clear personal ownership of shipped work. Wearables, biometrics, health technology, IoT, firmware testing, and data-pipeline experi
