🌟 Overview of the Role

Join a Fortune 200 clean energy leader to own their Hardware-in-the-Loop (HIL) test platform that validates control software for utility-scale Battery Energy Storage Systems. You'll work at the cutting edge of renewable energy technology, developing real-time plant models and ensuring BESS controllers perform flawlessly before deployment.

💼 Key Responsibilities

• Build and operate HIL rigs: configure Simulink Real-Time on Speedgoat, map I/O harness, and manage deterministic scheduling at ~1 ms base rates
• Create and maintain Simulink/Simscape Electrical models for PCS/inverter, filters/transformer, battery/BMS systems
• Connect Schneider M580 PLC to Speedgoat via Modbus TCP; verify commands, telemetry, time sync, alarms/events, and fail-safe sequences
• Author requirement-based tests for power/VAR control, ramp-rate, frequency/voltage response, SoC management, thermal derates, and fault scenarios
• Implement automated regression test suites with pass/fail metrics, waveform capture, and auto-reports; integrate with Git and CI workflows
• Analyze logs, isolate root causes across controller ↔ PLC ↔ plant model, file issues, verify fixes, and maintain full traceability

✅ Required Skills & Qualifications

Required:

• B.S./M.S. in Electrical, Controls, Power, Mechatronics Engineering or related field
• 3-7+ years in embedded/controls test & validation with HIL experience
• Strong MATLAB/Simulink skills including Simulink Test and Simulink Real-Time
• Hands-on Speedgoat experience at ~1 ms base rates (fixed-step solvers, rate transitions, task partitioning)
• PLC integration experience; Schneider M580 familiarity preferred
• Protocols: Modbus/TCP and DNP3 (command/telemetry, time-stamped events, buffers)
• Version control with Git; comfort with code reviews and branching strategies

Preferred:

• PE certification
• Simscape Electrical modeling experience
• Python and VBA scripting skills
• Experience with utility-scale solar, BESS, or power plant operations
