Power Electronics Mechanical Design Engineer — High-Current Production

Technical Talent Group; Berkeley (CA); On-site; USD 100,000 - 140,000; Full time

Job summary

100Hires, Inc. seeks a Mechanical Engineer specializing in power electronics to own the hardware path from battery cells to grid connections in a Berkeley onsite role. You will design busbars, harnesses, conductors and the enclosures and panels around them.

This design seat emphasizes creating components, not selecting off-the-shelf parts. You will perform thermal hand calcs, size components for heat, and work with contract manufacturers to scale production to thousands of units.

Qualifications

• 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.

Responsibilities

• 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 time.
