About the role
- 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.
- 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.
Responsibilities
- 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.
- 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.
- 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.
Requirements
- 3-5 years of experience as a power systems engineer, with hands-on experience in RTDS/RSCAD, HIL/CHIL testing, or real-time power system simulation.
- Strong experience with engineering simulation tools such as PSCAD, MATLAB/Simulink, or comparable platforms.
- Practical experience with communication networks, laboratory measurement equipment, and real-time simulation platforms such as RTDS, OPAL-RT, Typhoon HIL,
Compensation
- $170,000 - $220,000 USD
- Compensation will be commensurate with experience.
Company info
- 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.
