Job Summary
About Redwood Materials
Redwood is localizing a global battery supply chain that seamlessly integrates recovery reuse and recyclingkeeping critical minerals in circulation and driving the energy transition. Founded in 2017were 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.
Power Electronics Intern
The Power Electronics Engineering Intern will support the development of next-generation Pack Managers for Energy Storage Systems (ESS)utilizingrecycled batteries specifically for AI Data Centers. You willbe responsible forthe detailed power electronics design prototyping andpreparing forhigh-volume production of efficient cost-effective and technologically leading-edge power converters. Working with high-voltage systems and high-power levelsthis role requires a deep understanding of soft-switching DC-DC convertertopologies to ensure maximum performanceof the product. This is a Summer 2026 position.
Responsibilities Will Include:
- Design and develop high-voltage high-power (1500V 50kW) DC-DC resonant converters for recycled battery integration. Design and develop high-voltage high-power (1500V 50kW) DC-DC resonant converters for recycled battery integration
- Optimize converter to achieve consistent soft-switching ensuring high efficiency across a wide range of battery voltages during both charge and discharge modes. Optimize converter to achieve consistent soft-switching ensuring high efficiency across a wide range of battery voltages during both charge and discharge modes
- Develop high-fidelity transformer models and conduct detailed trade-off analyses between power density thermal constraints and cost
- Prototype andvalidate power stages performing bench testing to verify thermal performance and efficiency targets. validate power stages performing bench testing to verify thermal performance and efficiency targets
Desired Qualifications:
- MS or PhD candidate in Electrical Engineering with a focus on Power Electronics
- Deep theoretical and practical understanding of Resonant DC-DC converter modulation schemes (e.g. frequency modulation phase-shift control)
- Expertise in magnetics design using Ansys Maxwell for transformer modeling including inductance matrix extraction and detailed winding/core loss analysis
- Proficiency in simulation tools such as Simulink and LTspice for transient and steady-state circuit analysis
- Hands-on experience with Altium Designer for multi-layer PCB layout specifically for high-power and high-voltage creepage/clearance requirements
