Senior Engineer – HIL & Simulation

Overview

Senior Engineer – Hardware-in-the-Loop (HIL) & Simulation role owning and scaling HIL and simulation capabilities for utility-scale Battery Energy Storage Systems (BESS), serving as technical anchor for validating BESS controls, Battery Management Systems (BMS), and Power Conversion Systems (PCS).

What you'll do

• Define and execute the strategic roadmap for HIL testing, virtual commissioning, and simulation infrastructure, building real-time simulation test benches for physical controllers and embedded software.
• Develop and validate high-fidelity plant models, including battery cell/stack models, inverters, and power grid networks, using MATLAB/Simulink or RSCAD, alongside Software-in-the-Loop (SIL) test benches.
• Build automated test scripts and frameworks to integrate HIL/SIL testing into CI/CD pipelines, accelerating release cycles while maintaining quality gates.
• Simulate extreme grid disturbance events (such as ride-through and frequency response) and internal battery fault scenarios to verify system protection and control logic safely.
• Partner closely with firmware, controls, and systems engineering teams to analyze simulation data, reproduce field issues, verify bug fixes, and sign off on new software releases.
• Provide technical guidance and best-practice training to junior and mid-level engineers while standardizing workflows across New Product Introduction (NPI) cycles.

What you'll need

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Control Systems, or a related technical field (or equivalent professional experience).
• Minimum of 6 years of engineering experience in power electronics, renewable energy, or grid-tied systems.
• Minimum of 3 years of focused experience in HIL/SIL testing, real-time simulation, and control system validation.

Nice to have

• Hands-on experience with real-time HIL hardware and software platforms (Typhoon HIL, Opal-RT, or National Instruments).
• Strong proficiency in MATLAB/Simulink/Stateflow, PLECS, or C/C++ for model development and auto-code generation.
• Deep understanding of BESS architecture, including BMS, PCS, and Energy Management Systems (EMS).
• Familiarity with grid codes, utility interconnection standards (IEEE 1547, UL 9540), and power system dynamics.
• Experience with GE Mark VIe controllers and automated testing frameworks within CI/CD pipelines.

Details

• Remote position.
• Relocation assistance provided.
• Legally authorized to work in the United States required for this opening.
• Application deadline: January 25, 2027.
