HIL Test Engineer

Responsibilities

• Build and operate HIL rigs: configure Simulink Real-Time on Speedgoat, map I/O harness, and manage deterministic scheduling;
  Optimize solver settings for ~1 ms steps
• Model the plant: create/maintain Simulink/Simscape Electrical models for PCS/inverter, filters/transformer, battery/BMS;
  Validate model fidelity against bench/site data
• HIL simulation: connect Schneider M580 PLC to Speedgoat via Modbus TCP;
  Verify commands, telemetry, time sync, alarms/events, and fail-safe sequences end-to-end
• Author requirement-based tests: derive MiL/SiL/HIL cases for power/VAR control, ramp-rate, freq/volt response, SoC management, thermal derates, ride-through, startup/shutdown, and fault scenarios
• Automate regression: implement scripted test suites with pass/fail metrics, waveform capture, and auto-reports;
  Integrate with Git and CI workflows
• Defect lifecycle: analyze logs, isolate root causes across controller: PLC, plant model, file issues, verify fixes, and maintain full traceability (requirement: test, result)
• Rig reliability & safety: maintain configs/calibrations/harnesses, implement health checks, and observe lab

• B.S./M.S. in Electrical/Controls/Power/Mechatronics or related field
• 3-7 years in embedded/controls test and validation with HIL
• Strong MATLAB/Simulink skills (Simulink Test, Simulink Real-Time; Simscape Electrical)
• General programming/scripting experience (Python, VBA)
• Hands-on Speedgoat experience at ~1 ms base rates (fixed-step solvers, rate transitions, task partitioning)
• PLC integration experience;
  Schneider M580 familiarity preferred;
  Understanding of IEC 61131-3 concepts
• Protocols:
  Modbus/TCP and DNP3 (command/telemetry, time-stamped events, buffers)
• Version control with Git;
  Comfort with code reviews and branching strategies
• Clear communication, root-cause analysis, and documentation skills
