Responsibilities
You will be an early member of a product design team, responsible for the detailed power electronics design, prototype, and launch into high-volume production of an efficient, cost effective, highly manufacturable, and technologically leading-edge power converter
Familiar with high voltage (up to ~1,000 – 2,000VDC and 480VAC) and high power (~10 – 200kW) power converters, you can quantitatively compare and select topologies, control algorithms, semiconductors, and magnetics while respecting engineering constraints (efficiency, cost, reliability, simplicity, etc)
You understand both hard- and soft-switched topologies
Responsibilities include:
You can create highly accurate time-domain control and thermal models of your circuits to inform software and mechanical development, and while your core specialty is high-power circuitry design, you have a working understanding of microprocessor selection, electrical insulation, and thermal interface
Knowing how important circuit board layout is in high-power conversion, you’re willing to jump in and do the most critical parts of the powertrain layout yourself
The ideal candidate is highly self-driven, adaptable to a startup environment, and eager to take on technical challenges
You’re a doer, excited about working in a dynamic, fast-paced setting, and want to shape the electrical engineering function within a new department at Redwood
Qualification
Required
BS, MS, or PhD in Electrical Engineering, with a focus in power electronics

Strong understanding of power electronics topologies and fundamentals (AC/DC, DC/DC)
Experience with semiconductor selections, gate drive, and protection circuit design
Skilled in mentoring test technicians to design tests, interpret test results, and define part maturity criteria
Skilled at working with basic EE tools like oscilloscopes, network analyzers, signal Generators, etc
Proven track record as a electrical engineer, with hands-on design, prototyping, and launch experience in medium-to-high volume production (10,000 units/yr or higher)
Able to select circuit components for manufacturability as well as electrical function
Able to perform detailed schematic capture in Altium or related CAD software
Able to supervise (and occasionally perform) detailed layout of high-power electronics PCBs in Altium or related CAD software
Ability to perform the essential job functions consistent safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and/or quantitative productivity standards
Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other federal, state, and local standards
Ability to work in challenging working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods of time
Essential physical requirements, such as climbing, standing, stooping, or typing
Occasional work weekends, nights, or be on-call as a regular part of the job
Occasional travel requirements
