Job description

Staff Power Electronics Engineer | Energy Storage

San Francisco Bay Area, CA | 100% Onsite

$210,000-$230,000 Base Salary (depending on experience)

I'm partnering with an innovative US-based energy technology company to recruit an experienced Staff Power Electronics Engineer to help develop the next generation of high-power energy storage and power conversion systems.

This is a hands-on technical leadership opportunity for an engineer who enjoys taking complex power electronics hardware from initial concept through design, prototyping, validation and production.

The Opportunity

You'll be responsible for designing and developing high-voltage, high-power AC/DC and DC/DC converter systems, working on applications ranging from 10kW to 500kW.

The work involves challenging power conversion applications, with system voltages spanning approximately 800V to 25kV DC, depending on the architecture.

You'll work closely with multidisciplinary engineering teams to develop efficient, reliable and manufacturable hardware while providing technical guidance to other engineers.

What We're Looking For

• 8+ years of relevant power electronics engineering experience, ideally with an MS or PhD in Electrical Engineering.
• Proven hands‑on experience designing high-power inverter or converter hardware, not just controls, integration or testing.
• Strong understanding of AC/DC and DC/DC converter topologies and power-stage architecture.
• Experience with SiC, IGBT or other high-power semiconductor devices, including gate drivers and protection circuitry.
• Practical knowledge of magnetic components, transformers, inductors, thermal management and EMI/EMC.
• Experience with schematic capture, PCB design and hardware development tools such as Altium.
• Demonstrated ability to independently develop, prototype, troubleshoot and validate power electronics hardware.
• Ability to lead complex technical projects and mentor other engineers.

Relevant Industry Backgrounds

We're particularly interested in engineers with experience in:

• Battery energy storage systems (BESS)
• Grid-connected inverters and renewable energy
• EV traction inverters and onboard charging
• DC fast charging infrastructure
• Industrial motor drives and high-power supplies
• Aerospace and other advanced power conversion applications

You don't necessarily need energy storage experience. Engineers with strong high-power converter design experience from adjacent industries are encouraged to apply.

Why Consider This Opportunity?

You’ll have the opportunity to take ownership of technically challenging hardware development, influence power conversion architecture and work on technology supporting the future of energy storage.

This is a senior individual contributor position with meaningful technical ownership, rather than a people-management role.
