Power Electronics Engineer

Location: San Bruno, California, United States. U.S. work authorization is required within the first 3 days of employment.

Salary: $130,000–$180,000 annually, plus early-stage equity and company-sponsored benefits.

Company

hirify.global designs and manufactures power products for the U.S. military and its allies, enabling power generation to be decoupled from consumption in austere and resource-constrained environments.

What you will do

• Own the full-cycle design of DC/DC and DC/AC converters, protection circuits, isolation systems, and power distribution units across low- and high-voltage systems.
• Develop GaN and SiC inverter systems with advanced power-control schemes and design for low conducted and radiated emissions.
• Create schematics and oversee PCB layouts using Altium or equivalent, optimizing power density, thermal management, and EMI mitigation.
• Plan and execute hardware bring-up, verification, validation, environmental, and qualification testing using laboratory power and thermal measurement equipment.
• Collaborate with mechanical, firmware, and software engineers on enclosure integration, connectors, harnesses, thermal paths, and power-management specifications.
• Travel to military and non-military test sites, exercises, and global supplier engagements to support hardware evaluation in real conditions.

Requirements

• B.S. in Electrical Engineering; an M.S. is a plus.
• 2–5 years of power electronics hardware design experience, including at least 2 years with low- and high-voltage power conversion and management.
• End-to-end ownership of power electronics hardware from topology architecture and schematics through production.
• Experience with protection circuits, high-voltage isolation, DC/DC and DC/AC converter topologies, and analog or digital control-loop compensation.
• Experience with EMI/EMC requirements, filtering, layout practices, and conducted and radiated emissions; MIL-STD-461 familiarity is strongly preferred.
• Hands-on bench skills with oscilloscopes, power analyzers, thermal cameras, electronic loads, test fixtures, and mechanical or thermal constraints.

Nice to have

• Experience with GaN and SiC semiconductors, AC power conversion, transformers, or pulsed-load power delivery.
• Familiarity with UN 38.3, UL 2580, IEC 62133, MIL-STD-810, or MIL-STD-461 qualification requirements.
• Embedded firmware experience or collaboration with firmware teams on BMS and power management.
• Experience with LTspice, SIMPLIS, MATLAB/Simulink, or COMSOL.

Culture & Benefits

• High-ownership role as one of the first power electronics hires, with direct influence over products across multiple platforms and sectors.
• Prototype-to-production work on hardware supporting military and defense applications.
• Early-stage equity and access to company-sponsored benefit plans.
• Close interdisciplinary collaboration and opportunities to work with global suppliers and field-test hardware.
