Hardware Test Automation Engineer

Sesame - San Francisco, CA

Hiring: Hardware Test Automation Engineer Company: Sesame Location: San Francisco, CA Job Posted Time: 2026-09-17 11:55:38 Employment Type: Full-time Target Skills & Keywords : Android, CI/CD, Embedded Systems, Firmware, Python, Sanity, iOS About the job Required Skills: •This is a high-ownership, high-visibility role at the firmware/wireless/hardware boundary, on a small team that moves fast. You'll partner closely with the firmware team and our hands-on platform tester, and you'll have visibility and authority across both the firmware and the testbed so the two are built to cooperate. •Stand up an automated test framework driven from a programmable Bluetooth central (Android, iOS, or a Pi-based rig, whatever fits), firmware-first then integration-first; even if early runs are short, get the foundation in place before it scales. •Establish nightly (sanity/stability) and weekly (stress) automated runs, with extended weekend runs for long-duration audio sessions (e.g., 5-hour and 18-hour using synthetic data). •Begin a live performance/stress dashboard: A2DP/throughput, BT link duration, BT latency, battery life, firmware crash counts, and regression flags. •Design, build, and own an automated hardware test rig integrated with CI/CD (build → flash → run → report) for the device. •Implement throughput/bandwidth, connectivity stress tests (e.g., iPerf, A2DP/AVRCP), including sustained-throughput, connection-stability/range testing, and simulated degraded-connectivity scenarios. •Build API-level tests (easier to automate than full end-to-end iOS flows) 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). Qualifications: •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). You understand what to test, not just how to automate. •Strong scripting/programming (e.g., Python) and the ability to build harnesses and dashboards from scratch. •Comfortable operating in an early-stage, prototype-hardware environment with limited units and evolving specs. •Performance instrumentation experience: latency, sustained throughput, IPC/cycle count, and thread- and core-level tracing on embedded/multi-core platforms. •Operational familiarity with Qualcomm chipsets and tooling (e.g., DSP framework, PyDebug) and the realities of vendor bug turnaround. •Battery and thermal test methodology. •Sesame is committed to a workplace where everyone feels valued, respected, and empowered.
