Job summary

Sesame is seeking a dedicated Hardware Test Automation Engineer to own the automated test rig for the Cypress wearable AI device. You’ll drive CI/CD integration, automate flashing, test execution, and reporting across firmware, wireless, and hardware, enabling nightly stability and long‑duration audio runs.

You’ll partner with firmware and QA to define what to automate, build dashboards, and establish pass/fail thresholds, delivering reliable quality metrics to investors and customers from our

Qualifications

• Hands-on experience building hardware/embedded test automation and integrating it into CI/CD.
• Solid wireless/networking fundamentals: Bluetooth audio (A2DP/AVRCP), BLE, and throughput testing (e.g., iPerf).
• Strong scripting/programming (e.g., Python) and the 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.

Responsibilities

• Design, build, and own an automated hardware test rig integrated with CI/CD (build → flash → run → report) for the Cypress 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/cherry‑picked test runs when the team needs targeted coverage.
• Partner with firmware (and the QA coordinator) to define what is automated vs. manual, API vs. integrated, and which platform drives the rig.
