Role summary
Owns one core HIL regression pillar so the team stops context-switching across all of them. Builds and maintains automated HIL frameworks, dashboards, and CI so component-, module-, and firmware-level validation on the HILs is fast, reliable, and continuous during the V6 push.
Key responsibilities

• Develop and maintain the HIL test environment combining physical hardware (ECUs, sensors, motor controllers) with simulated dynamics for stress and fault-injection testing.
• Build and maintain automated test frameworks, reporting, dashboards, and the AI analyzer; keep CI jobs on the HILs green.
• Expand the 30+ module self-tests and improve the associated data pipeline; own regression and smoke test coverage.
• Integrate high-speed DAQ and bus tracing (CAN, I2C, Ethernet) for deep hardware and firmware diagnostics.
• Partner with robot SW and Nimble Health to improve the simulation models used on the HILs.
• Lead physical pick/pack testing: evaluate and optimize SKU pickability, grip reliability, and placement accuracy

Qualifications

• BS or MS in Electrical, Computer, or Robotics Engineering.
• 1-3+ years validating embedded systems, control software, or robotics firmware; HIL experience strongly preferred.
• Strong Python (and Rust or C++) for automated test scripts and analysis; CI/CD experience (e.g., Jenkins).
• Understanding of digital/analog I/O and robotics comms (CAN, Ethernet, USB, Serial); MATLAB/Simulink a plus.
• Comfortable with requirements traceability and defect management.

Compensation
The pay range for this position at the start of employment is expected to be between $130,000 and $170,000/year.
