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 experience are especially relevant. Strong experience with other connected products is welcome. Why Join Take ownership across the entire product, shape the quality function, and make a visible difference to a platform people rely on every night.
