About the role

Hardware Test Automation Engineer at Sesame, responsible for building and owning the automated test framework, test rigs, and live dashboards to validate a wearable AI hardware device across firmware, wireless, and hardware boundaries.

Responsibilities

  • 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 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 for targeted coverage.
  • Partner with firmware and QA coordinator to define automated vs manual scope, API vs integrated, and rig ownership.

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).
  • Strong scripting/programming skills (e.g., Python) and ability to build harnesses and dashboards from scratch.
  • Experience defining test plans, metrics, and pass/fail thresholds from real data.
  • Comfortable operating in an early-stage, prototype-hardware environment with limited units and evolving specs.
