Electrical Engineer – Power Electronics Hardware

About the role

We’re a venture-backed hardware startup in San Francisco building high-performance power conversion systems for modern electrified machines.

We’re looking for a hands-on Electrical Engineer to support product development from early design through production. This is a broad hardware engineering role—not a narrow specialist position. You’ll work across schematics, PCB reviews, power electronics simulations, wiring harnesses, test setups, lab debugging, manufacturing equipment, technical documentation, vendors, and production support.

We value sound engineering judgment, curiosity, ownership, and the ability to turn ideas into reliable working hardware. The bar is high. When you encounter a difficult problem, we expect you to investigate it, test solutions, and find a path forward.

What you’ll do

• Run complex power electronics simulations and analyze system performance
• Perform parasitic PCB extraction and evaluate layout-related behavior
• Review schematics, PCB layouts, component selections, and design tradeoffs
• Design, assemble, test, and bring up production hardware
• Develop and bring up hardware for manufacturing and test lines
• Create test setups and execute hardware validation plans
• Debug real-world problems involving EMI, grounding, thermal performance, signal integrity, and manufacturing defects
• Support wiring harnesses, connectors, sensors, and system-level integration
• Work closely with firmware, mechanical, manufacturing, and test engineers
• Coordinate with component suppliers and manufacturing vendors
• Create clear engineering documentation, test procedures, and design records
• Support products as they move from prototype to production

What we’re looking for

• Hands-on experience designing and debugging electronic hardware
• Moderate experience with schematic design, PCB development, and board bring-up
• Understanding of fundamental electrical engineering principles
• Familiarity with power electronics, switching systems, or high-power hardware
• Experience using common laboratory equipment such as oscilloscopes, power supplies, electronic loads, and multimeters
• Ability to analyze unfamiliar technical problems and learn quickly
• Strong engineering judgment and attention to detail
• Resilience when working through difficult or ambiguous hardware problems
• Ability to take ownership and execute with limited supervision
• Clear written and verbal communication skills

Nice to have

• Experience with high-power or high-voltage electronics
• Experience with power conversion systems, motor drives, inverters, or DC-DC converters
• Familiarity with SPICE or other power electronics simulation tools
• Experience with PCB parasitic extraction
• Knowledge of EMI/EMC, grounding, thermal design, and signal integrity
• Experience developing manufacturing fixtures or automated hardware test systems
• Experience supporting hardware from prototype through production
• Experience working in a fast-moving startup environment

Why join us?

You’ll work directly on hardware that pushes the limits of power density and performance. You’ll have broad ownership, significant technical responsibility, and the opportunity to influence products from their earliest designs through manufacturing and deployment.

This position is based in San Francisco and involves substantial hands-on laboratory work.
