What You’ll Be Doing

• Own the Io
  T/embedded test strategy — define standards, tooling, and metrics for functional, regression, performance, and stress testing of
  - locker devices.
• Design and implement automated test frameworks (HIL, SIL, network simulators) that integrate with our CI/CD pipeline for every firmware and hardware release.

• Mentor QA and engineering peers, evangelizing best practices and fostering a
  - first culture across the company.

What You’ll Bring To The Table

• 7+ years of
  - on testing experience with embedded or Io
  T products (MCUs, So
  Cs, gateways) in
  - availability environments.
• Proficiency in Python (Py
  Test, Robot, or similar) and at least one systems language (C/C++, Rust, or Go) for
  - level test harnesses.
• Demonstrated success building HIL/SIL frameworks, automated stress rigs, or environmental chambers and integrating them into CI (Git
  Lab/Git
  Hub Actions, Jenkins, etc. ).
• Deep understanding of embedded Linux/RTOS internals, bootloaders, OTA mechanisms, and common Io
  T protocols (MQTT, HTTP, BLE, CAN, Modbus, etc. ).
• Experience with lab instrumentation and measurement tools (oscilloscopes, logic analyzers, power analyzers, network emulators).
• Strong analytical skills — able to turn raw logs, metrics, and telemetry into actionable insights that raise product reliability.
• Fluency in English, both verbal and written.

Nice to Have

• Familiarity with cloud Io
  T platforms (AWS Io
  T Core, Azure Io
  T, GCP) and
  -
  - cloud observability stacks.
