Power Electronics Engineer, Energy Storage

Overview

Power Electronics Engineer, Energy Storage

— Redwood Materials. Join to apply for the

Power Electronics Engineer, Energy Storage

role at

Redwood Materials .

About Redwood Materials:

we're 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.

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.

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.

If necessary, we will adjust the job level to suit your experience and responsibilities. The qualifications below are just that – desired – if you feel you're highly qualified for this role but are missing a few of the below line items, we encourage you to apply anyway.

Qualifications

BS, MS, or PhD in Electrical Engineering, with a focus in power electronics

7+ years of experience in electrical engineering, with a strong focus in power conversion or energy storage products, ideally for mass production

Experience in high-voltage (up to 2000VDC, and 480VAC) design

Intimately familiar with techniques for efficiency optimization

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

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

Physical Requirements

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

Working Conditions

Environment, such as office or outdoors

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

California Pay Range: $145,500—$196,500 USD

The position is full-time. Compensation will be commensurate with experience.
