## About the role

We're looking for a Hardware-in-the-Loop (HIL) Test Engineer to own the test station for Mill Commercial's program including hardware, sensor and actuator emulation, and plant models: systems to emulate include safety interlocks, load cells, motor feedback, thermocouples, and heater elements. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 4+ years in test, controls or systems engineering on electromechanical products, with at least 2 years hands-on with HIL or real-time simulation rigs
- Strong Simulink and MATLAB: you've built and tuned plant models (thermal, mechanical or electrical) and deployed them to a real-time target
- Able to read and trace C code: you can follow firmware control logic well enough to understand what a test is exercising and where a failure originates
- Comfortable with signal-level work: thermocouples, strain gauges, hall-effect and discrete inputs, PWM drive lines, and the I/O modules that emulate them
- Practical bench skills: wiring, harness build, oscilloscope and DMM work
- Strong documentation and organization skills
