Job Description
The Power Electronics Engineer at Redwood Materials is responsible for designing, prototyping, and launching high-power, high-voltage power converters for energy storage applications, contributing to the development of efficient, cost-effective, and manufacturable power electronic systems in a fast-paced, innovative environment.
Key Responsibilities
- Design, prototype, and launch high-power, high-voltage power converters for energy storage applications.
- Select and optimize power electronics topologies, control algorithms, semiconductors, and magnetics to meet efficiency, cost, and reliability goals.
- Create accurate time-domain control and thermal models to inform software and mechanical development.
- Perform circuit board layout and supervise PCB design for high-power electronics.
- Select circuit components for manufacturability and electrical performance.
- Conduct detailed schematic capture and layout of high-power electronics using CAD tools like Altium.
- Mentor test technicians in designing tests, interpreting results, and defining part maturity criteria.
Requirements
- Bachelor's, Master's, or PhD degree in Electrical Engineering, with a focus in power electronics.
- At least 7 years of experience in electrical engineering, with a strong focus in power conversion or energy storage products, ideally for mass production of 10,000 units per year or higher.
- Experience in designing high-voltage systems up to 2000VDC and 480VAC.
- Familiarity with techniques for efficiency optimization in power electronics.
- Basic knowledge of control theory and embedded systems.
- Strong analytical problem solving skills.
- Experience in rapid iterations on prototypes based on customer, supplier, and co-worker feedback.
- Deep understanding of power electronics topologies and fundamentals, including AC/DC and DC/DC conversions.
- Experience with semiconductor selections, gate drive, and protection circuit design.
- Proven track record as an electrical engineer with hands-on design, prototyping, and launch experience in medium-to-high volume production.
- Ability to select circuit components for manufacturability as well as electrical function.
- Ability to perform detailed schematic capture in Altium or related CAD software.
- Ability to supervise and occasionally perform detailed layout of high-power electronics PCBs in Altium or related CAD software.
- Ability to create highly accurate time-domain control and thermal models of circuits to inform software and mechanical development.
- Understanding of electrical insulation and thermal interface considerations.
- Willingness to perform critical parts of powertrain layout and circuit board layout yourself.
- Physical ability to perform essential job functions safely and successfully, including climbing, standing, stooping, and typing, consistent with ADA, FMLA, and other standards.
- Ability to maintain regular, punctual attendance.
- Ability to work in challenging conditions that may include exposure to noise, dust, chemicals, and temperature extremes while protected by PPE.
- Willingness to work occasional weekends, nights, or be on-call as a regular part of the job.
- Willingness to undertake occasional travel as required.
