About this role

Sesame is seeking a Hardware Test Automation Engineer to build the automated test infrastructure for Cypress, a wearable AI device. You'll design and own a complete test rig integrated with CI/CD, establish nightly and stress test runs, and create a live performance dashboard that gates releases and informs product quality decisions.

What you'll do

  • Design and own an automated hardware test rig with CI/CD integration (build, flash, run, report)
  • Implement wireless connectivity and throughput tests including A2DP, AVRCP, BLE, and simulated degraded scenarios
  • Build API-level and long-duration audio session tests with battery/thermal characterization
  • Create and maintain a live performance dashboard with regression detection and safety thresholds
  • Develop diagnostic tooling and support automated bug triage for hardware/firmware issues
  • Partner with firmware teams to define automation scope and provide daily summaries and ad hoc test runs

What they're looking for

  • Hardware and embedded test automation with CI/CD integration
  • Bluetooth audio protocols (A2DP, AVRCP, BLE) and wireless networking fundamentals
  • Python or strong scripting/programming for test harnesses and dashboards
  • Test planning, metrics definition, and pass/fail threshold analysis
  • Performance instrumentation (latency, throughput, tracing on embedded systems)
  • Programmable Bluetooth central platforms (Android, iOS, Raspberry Pi)
  • Consumer hardware product testing experience (optional but valued)
  • Qualcomm chipsets and vendor tooling familiarity (optional)
