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. 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++
