Microgrid Controls 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. S. for the first time, all from batteries we already have.

Responsibilities

will include: Design, develop, and implement plant-level microgrid control algorithms for BESS operating in both grid-following (GFL) and grid-forming (GFM) modes, from concept through validated deployment. Design and architect the site controller to manage GFL inverters in direct P/Q, power factor, and voltage/frequency droop modes, and to process Vref and Fref commands to the GFM inverter. Implement active and reactive power control (P/Q), voltage and frequency control (V/F), and droop-based control strategies to coordinate generating assets operating as GFL with BESS as GFM master.

Design control systems that integrate BESS with other assets including solar PV, gensets, and loads for applications spanning utility-scale power plants, off-grid and islanded microgrids, and data center power. Develop and modify control algorithms in PSCAD and/or MATLAB/Simulink, and verify performance through simulation and HIL environments including RTDS and/or Typhoon HIL. Verify MGC behavior under normal operating conditions and abnormal system events, including fault scenarios, mode transitions, and disturbances, using simulation, HIL, and field testing.

Develop simulations and workflows to test and troubleshoot BESS site controller behavior prior to and during field deployment. Translate validated control designs into clear implementation specifications for production software teams, and support integration and commissioning activities as needed.

Requirements

driven by customer and grid needs.

and grid operations is a plus. Proficiency in Rust and/or C++ for real-time or embedded control applications is a plus. Comfortable collaborating across disciplines and communicating clearly with power systems, firmware, software, and field engineering teams.

Qualifications

: MS or PhD in Electrical Engineering, Power Systems, or Controls Engineering. 3 to 6 years of hands-on experience designing and implementing microgrid or BESS plant controllers, with direct experience taking control designs from Simulink into a real-time site controller platform. Strong foundation in control systems, including linear control theory, PI controllers, low-pass filtering, limiters, and anti-windup techniques.

Solid understanding of GFL and GFM inverter concepts, including frequency and voltage droop for both inverters and synchronous generators. Clear understanding of what a plant or site controller does for BESS in both grid-connected and islanded modes. Demonstrated experience with HIL validation using RTDS and/or Typhoon HIL.

Practical experience with islanded microgrid operation including black start, resynchronization, and mode transitions. Practical understanding of P/Q control and energy management, including SoC-based charge and discharge constraints. Familiarity with microgrid protection concepts and the ability to reason about fault behavior across different operating modes.

Experience supporting commissioning, troubleshooting, or operational validation of BESS or power systems in a lab or field environment.
