Power Systems Engineer, Hardware in Loop

About Redwood Materials Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling  —  keeping critical minerals in circulation and driving the energy transition. Founded in 2017,  we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have. Responsibilities will include:   Design, develop, and validate power system and inverter control strategies using RTDS/RSCAD to meet project-specific grid requirements, including grid-forming and grid-following operation, ride-through, droop control, and microgrid performance.   Develop and maintain Controller Hardware-in-the-Loop (CHIL) test platforms integrating RTDS with inverter controllers, site controllers, protection relays, metering, and communication interfaces; create test plans, automate test execution, analyze results, and maintain clear technical documentation.   Build and validate real-time power system models of BESS, PV, inverters, transformers, generators, loads, and balance-of-plant equipment for both grid-connected and islanded applications.   Perform dynamic and transient studies to evaluate system stability, black start, load pickup, inverter interactions, fault response, protection performance, and transitions between operating modes.   Identify and resolve control, modeling, communication, and hardware-in-the-loop integration issues using first-principles power system analysis, simulation results, and structured troubleshooting.   Support validation and benchmarking of PSCAD, PSS/E, and other offline simulation models against RTDS/CHIL results and field performance where applicable.   Develop and expand in-house RTDS laboratory capabilities, including model integration, I/O scaling, communication interfaces, test automation, equipment selection, and standardized validation procedures.   Desired Qualifications:   MS or PhD in Electrical Engineering, Power Systems, Controls, or a closely related discipline.   Proven experience developing and supporting integrated hardware and software test environments, including hands-on troubleshooting and debugging.   Ability to develop test automation, scripts, or control functions using Python, C, C++, or a similar programming language.   Strong experience with engineering simulation tools such as PSCAD, MATLAB/Simulink, or comparable platforms.   Solid understanding of electrical engineering fundamentals, circuit behavior, and control theory.   Practical experience with communication networks, laboratory measurement equipment, and real-time simulation platforms such as RTDS, OPAL-RT, Typhoon HIL,    In accordance with California pay transparency laws, the salary range for this position is listed below. Actual compensation may vary based on a variety of factors, including experience, education, and skills.  California Pay Range: $145,200 — $215,000 USD The position is full-time.
