Job Description
The Power Electronics Controls 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 electronics 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 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 oversee prototype testing and validation.
Requirements
- Experience in high-voltage power electronics design up to 2000VDC and 480VAC, including familiarity with techniques for efficiency optimization.
- 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.
- Proven track record as an electrical engineer with hands-on experience in detailed circuit design, prototyping, and launching products into medium-to-high volume production.
- Ability to create highly accurate time-domain control and thermal models of circuits to inform software and mechanical development.
- Knowledge of high-power circuitry design, including understanding of both hard- and soft-switched topologies.
- Experience in selecting 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.
- Experience with semiconductor selections, gate drive, and protection circuit design.
- Strong analytical problem-solving skills related to power electronics and energy storage systems.
- Experience in rapid iterations on prototypes based on customer, supplier, and co-worker feedback.
- Familiarity with techniques for efficiency optimization in power electronics.
- Basic knowledge of control theory and embedded systems.
- Skilled in working with basic EE tools such as oscilloscopes, network analyzers, and signal generators.
- Ability to mentor test technicians to design tests, interpret test results, and define part maturity criteria.
- Understanding of power electronics topologies and fundamentals including AC/DC and DC/DC conversions.
- Physical ability to perform essential job functions safely and successfully, including climbing, standing, stooping, and typing, consistent with ADA, FMLA, and other standards.
- Willingness to work in challenging conditions that may include exposure to noise, dust, chemicals, and temperature extremes while protected by PPE.
- Availability to work occasional weekends, nights, or be on-call as part of the job, and occasional travel as required.
