Hardware Test Automation Engineer
Build and own automated test rigs and CI/CD-integrated frameworks for Sesame's Cypress wearable AI hardware. Design stress, throughput, long-duration audio, and battery tests; create performance dashboards that gate releases. Requires embedded test automation experience, Bluetooth/wireless expertise, and Python scripting in a fast-moving early-stage environment.
About the job
Responsibilities
- Design, build, and own an automated hardware test rig integrated with CI/CD (build → flash → run → report) for the Cypress wearable AI device.
- Implement throughput/bandwidth and connectivity stress tests (e.g., iPerf, A2DP/AVRCP), including sustained-throughput, connection-stability/range testing, and simulated degraded-connectivity scenarios.
- Build API-level tests covering throughput, sustained load, and crash detection.
- Run long-duration audio session testing (multi-hour, synthetic data) and battery/thermal performance characterization (including full discharge cycling).
- Build and maintain a live performance & stress dashboard with defined safety thresholds and target benchmarks; automatically flag regressions.
- Develop diagnostic tooling and support automated bug triage for hardware/firmware issues.
- Provide daily automation summaries and updates; support ad hoc test runs.
- Partner with firmware and QA teams to define automation scope vs. manual testing.
Requirements
- Hands-on experience building hardware/embedded test automation and integrating it into CI/CD (automated flashing, execution, and reporting).
- Solid wireless/networking fundamentals: Bluetooth audio (A2DP/AVRCP), BLE, and throughput testing (e.g., iPerf).
- Strong scripting/programming (e.g., Python) and ability to build harnesses and dashboards from scratch.
- Experience defining test plans, metrics, and pass/fail thresholds from real data.
- Comfort operating in an early-stage, prototype hardware environment with limited units and evolving specs.
Nice-to-Haves
- Experience owning an automation testbed for a shipping consumer hardware product (wearables, audio devices, smart cameras, IoT).
- Performance instrumentation experience: latency, sustained-throughput, IPC/cycle-count, and thread/core-level tracing on embedded/multi-core platforms.
- Familiarity with Qualcomm chipsets and tooling (e.g., DSP framework, PyDebug).
- Experience automating from a programmable Bluetooth central: Android, iOS, a Pi-based rig, or similar.
- Battery and thermal test methodology.
- Experience with sensor/IMU testing and creative physical test setups for connectivity/range.
