About the role
- Strong foundation in classical and modern control theory including PID tuning, state-space modeling, small-signal stability analysis, and frequency-domain analysis (Bode plots)
- Solid understanding of synchronous machine dynamics, excitation and governor systems, and system-level stability concepts (frequency stability, voltage stability, weak grid operation).
- 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 plant controller functions for battery energy storage systems including voltage regulation, frequency regulation, P-f and Q-V droop control, active/reactive power control loops, and fast frequency response.
- Build and strengthen in-house modeling capabilities for Redwood Energy's products in PSCAD and PSSE, including model validation against field and controller-hardware-in-the-loop behaviors.
- Work with the product and controls design teams to translate power system requirements into site controller and inverter controller specifications, influencing system and plant-level control architecture.
Requirements
- 3+ years of experience in power system studies, dynamic modeling, inverter-based resources, or grid integration of energy storage and renewable energy systems.
- Expert proficiency in MATLAB/Simulink for control algorithm development and testing.
- Hands-on experience with inverter-based resource modeling including grid-forming and grid-following control, PLL design, virtual inertia, and droop-based power control.
Nice to have
- MS or PhD in Electrical Engineering with specialization in power systems and control systems (PhD preferred).
- Experience with real-time simulation and CHIL environments (RTDS, OPAL-RT, Typhoon HIL) is strongly preferred.
- Experience performing or supporting transmission-level engineering studies such as transient stability, protection coordination, harmonics, and insulation coordination is a plus.
- Familiarity working with utilities, ISOs, or renewable project developers is a plus
Skills
- Skills, Knowledge, and Abilities
- Actual compensation may vary based on a variety of factors, including experience, education, and skills.
Compensation
- $160,000 - $210,000 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.
- 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.
