Power Systems Engineer, Energy Storage

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 2019, 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.

Role: Power Systems Engineer ,Energy Storage

Responsibilities will include: 

• Work with the product and controls design teams to translate power system requirements into site controller and inverter controller specifications, influencing6 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++ 

 Desired Qualifications: 

• 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. 

Physical Requirements:  

• Ability to perform the essential job functions consistent safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and/or quantitative productivity standards
• Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other federal, state, and local standards 

Working Conditions:  

• Environment, such as office or outdoors
• Ability to work in challenging working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods of time
• Essential physical requirements, such as climbing, standing, stooping, or typing
• Occasional work weekends, nights, or be on-call as a regular part of the job
• Occasional travel requirements
