The opportunity

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 2017, we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.

What you'll do

  • Software-Defined Power: Design and optimize advanced control algorithms for high-power BESS, focusing on grid-forming, grid-following, and complex multi-asset energy site synchronization

  • High-Power Conversion Architecture: Develop bidirectional DC/DC and AC/DC control schemes for industrial-scale storage, ensuring peak efficiency, thermal stability, and safety across all operating modes

  • Digital Twin Development: Build high-fidelity "Digital Twins" of power stages and grid environments using PLECS and MATLAB/Simulink to predict system behavior under extreme transient and fault conditions

  • Virtual & Hardware Validation: Architect and lead comprehensive Hardware-in-the-Loop (HIL) testing environments (Opal-RT/Typhoon) to rigorously stress-test control firmware before deployment

  • Circular Asset Integration: Collaborate with battery and systems teams to implement control strategies that optimize the performance and longevity of mixed-asset arrays, including the integration of recycled battery chemistries

  • Cross-Functional Leadership: Partner closely with electrical, firmware, and thermal engineers to define the long-term roadmap for modern, resilient energy storage site controllers

What they're looking for

  • Educational Depth: MSc or PhD in Electrical Engineering with a specialization in Power Electronics Control Systems. (MSc requires 3+ years of relevant industry experience; PhD preferred)
  • Topology Mastery: Deep theoretical and practical mastery of high-efficiency power conversion. You are an expert in resonant topologies (LLC, CLLC, DAB) and advanced multi-level architectures, specifically Flying Capacitor (FC) and Active Neutral Point Clamped (ANPC)
  • Control Theory Expertise: Proven ability to design robust closed-loop controllers (Bode, Nyquist, State-Space) and implement them effectively on digital signal processors (DSPs) or microcontrollers
  • Modern Toolchain: Expert-level MATLAB/Simulink and PLECS for modeling and simulation
