ME - Power Electronics Design

JOB TITLE Mechanical Engineer, Power Electronics (Contract)

LOCATION:

Berkeley, CA (onsite)
TYPE: 6-month contract to hire ABOUT

THE ROLE Our client is a venture-backed energy storage company building grid-scale battery systems. They're moving from their first customer sites into high-volume production, and they need mechanical engineers who can design the power path and get it ready to build thousands of times a year.

You'll own the hardware that carries current from the battery cells out to the grid connection: busbars, harnesses, conductors and the enclosures and panels around them. This is a design seat, not a parts selection seat. You'll be designing the components, not picking them out of a catalog.

WHAT YOU'LL DO
- Design and size busbars, harnesses and conductors for high-current power paths
- Run thermal hand calcs and build Excel tools to size components for heat generated and dissipated
- Package electrical components inside large enclosures
- Design sheet metal panels and enclosure parts for production
- Rework existing designs to cut cost and assemble reliably on a production line
- Work with suppliers and contract manufacturers to get parts right the first timeWHAT YOU NEED- BS in Mechanical Engineering- 2+ years in power electronics mechanical design (EV, battery packs, energy storage, high voltage equipment or similar)- Hands-on experience designing busbars, harnesses or other conductors
- Solid thermal fundamentals: energy balance, heat generation and dissipation, component sizing
- At least one product taken from concept through production
- Real DFM experience on production parts (machined, sheet metal, plastic or copper), not just prototypes
- Able to work onsite in Berkeley, CANICE TO HAVE
- High voltage DC systems experience
- Low to mid volume manufacturing ramp experience
- Experience working directly with contract manufacturers- CAD and GD&T (Solid Works, Creo, NX or similar)
WHY THIS ONEGrid storage is one of the fastest growing corners of energy, and this team is past the science project stage and into real production. You'll do hands-on design work that ships, on a product that's still being figured out. It's not another iteration of a well-defined box.
