About Redwood Materials
Redwood Materials was founded in 2017 by JB Straubel, co-founder and former CTO of Tesla, on a simple but radical idea: the critical minerals powering the energy transition already exist. They just need to come back. Today Redwood is the largest lithium-ion battery recycler in North America — recovering, refining, and redeploying critical minerals from end-of-life batteries back into the supply chain. On the energy side, Redwood has deployed the largest second-life battery project in the world, delivering power to AI data centers in months rather than years using proprietary energy architecture engineered entirely in-house. The company is profitable, the market it operates in is projected to grow 20 to 50 times over the next decade, and Redwood is the only company with the supply chain, the technology, and the operational scale to lead it.
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,
