Responsibilities
- Own firmware release quality by defining test criteria, running release qualification, and signing off on firmware releases.
- Partner with firmware developers to define test strategies, close coverage gaps, and provide early feedback.
- Build hardware-in-the-loop test rigs for boards, actuators, and complete robot setups, including fault injection and real-time bus validation.
- Develop automated Python regression suites that run in CI and convert field and fleet issues into regression tests.
- Validate safety-critical and security behaviors, including fault detection, current and thermal limits, safe torque-off, secure boot, and firmware signing.
- Test recovery from interrupted updates, power loss during flashing, corrupted images, and watchdog resets through soak and stress testing.
- Use manual bench testing, custom fixtures, scopes, logic analyzers, and bus analyzers to isolate firmware, hardware, and test-setup issues.
Requirements
- Bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field, or equivalent experience, with 2+ years of firmware or embedded systems testing.
- Experience testing embedded systems at the hardware-software boundary, including timing and fault conditions, and reading embedded C/C++ to design targeted tests.
- Experience building test automation in Python and Bash using Git and CI systems such as GitHub Actions, Jenkins, or Buildkite.
- Experience with CAN, UART, I2C, and SPI communication protocols.
- Hands-on experience with oscilloscopes, logic analyzers, power supplies, electronic loads, and bus analyzers.
- Preferred experience building HIL test systems and automation frameworks such as pytest or Robot Framework.
- Preferred experience testing motor control or power electronics firmware, including BLDC/PMSM drives, battery management systems, power distribution, EtherCAT, or CAN FD.
- Familiarity with IEC 61508, ISO 13849, ISO 26262, IEC 62443, or ISO/SAE 21434 and requirements traceability or verification is preferred.
- Preferred embedded security testing experience involving secure boot, code signing, hardware security modules, TPMs, fuzzing, penetration testing, or fault-injection attacks.
- Familiarity with FreeRTOS, SafeRTOS, or Zephyr and robotics, automotive, or IoT device backgrounds is preferred.
Benefits
- Comprehensive medical, dental, and vision coverage.
- Generous paid time off, company holidays, and parental leave.
- 401(k) plan with company match.
- Flexible Spending Account and Health Savings Account options.
- Commuter benefits for transit and parking.
- Short-term and long-term disability and life insurance.
