## Job description

## 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.

Position Summary:

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. 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. The Power Systems Engineer, Energy Storage develops and validates power system models, controls, and interconnection solutions for Redwood’s energy storage systems. The role supports grid-connected and off-grid projects through PSCAD/PSSE modeling, controller and inverter specifications, CHIL testing, and compliance with utility, ISO, and IEEE requirements.

Essential Duties and Responsibilities

- 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.
- 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.
- Ensure control algorithms meet utility, ISO, and IEEE requirements including ERCOT interconnection specifications and IEEE 2800 compliance.
- 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.
- Set up and execute CHIL testing on platforms such as RTDS, OPAL-RT, or Typhoon HIL to validate inverter and site controller performance under grid disturbance and fault scenarios.
- Develop automation tools for PSCAD and PSSE for interconnection studies using Python, C, or C++

Skills, Knowledge, and Abilities

- 3+ years of experience in power system studies, dynamic modeling, inverter-based resources, or grid integration of energy storage and renewable energy systems.
- MS or PhD in Electrical Engineering with specialization in power systems and control systems (PhD preferred).
- Strong foundation in classical and modern control theory including PID tuning, state-space modeling, small-signal stability analysis, and frequency-domain analysis (Bode plots)
- Expert proficiency in MATLAB/Simulink for control algorithm development and testing.
- Experience developing and validating user-defined inverter or plant controller models in PSCAD and/or PSSE.
- Hands-on experience with inverter-based resource modeling including grid-forming and grid-following control, PLL design, virtual inertia, and droop-based power control.
- Solid understanding of synchronous machine dynamics, excitation and governor systems, and system-level stability concepts (frequency stability, voltage stability, weak grid operation).
- Experience with real-time simulation and CHIL environments (RTDS, OPAL-RT, Typhoon HIL) is strongly preferred.
- Programming experience in Python, C, or C++ for model automation, controls integration, or testing workflows.
- 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

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.
