Senior Electrical Hardware Test Engineer, Energy Storage

Location: San Francisco, California, United States

Salary: $145,000–$192,000 USD annually

Company

hirify.global recovers, refines, and redeploys critical minerals from end-of-life lithium-ion batteries and develops proprietary energy storage systems.

What you will do

• Design, set up, and execute validation tests for high-voltage power electronics components and assemblies operating at 400–2000VDC and 480–800VAC.
• Analyze schematics, Altium layouts, and datasheets to understand circuit behavior and inform test design.
• Debug hardware at the bench, probe circuits, isolate faults, and investigate root causes to the component level.
• Design, fabricate, and source custom PCBAs for component-level characterization.
• Build electrical-focused test infrastructure spanning electrical, mechanical, and software domains.
• Develop Python-based test automation and data analysis tools, collaborate on FMEAs and test plans, and drive design and process improvements.

Requirements

• Master’s degree in Electrical Engineering, Mechatronics, or a related field.
• 5+ years of technical experience in test engineering, hardware validation, or power electronics development.
• Hands-on experience with high-voltage systems operating at 400–2000VDC and 480–800VAC.
• Proficiency with Altium or similar EDA tools and fluency reading schematics, layouts, and component datasheets.
• Hands-on experience with oscilloscopes, probes, and general laboratory instrumentation.
• Working knowledge of power conversion, including switching topologies, gate drive, isolation, protection, and thermal behavior.
• Demonstrated root-cause and failure-analysis experience, tracing failures to components or mechanisms rather than only documenting symptoms.
• Proficiency in object-oriented programming; Python is preferred.
• Excellent communication and interpersonal skills, including the ability to engage stakeholders at all organizational levels, including executives.
• A get-it-done attitude and willingness to handle both large and small tasks.

Culture & Benefits

• Full-time employment with compensation commensurate with experience.
• Work focused on energy storage systems and high-voltage power electronics.
• Cross-functional collaboration with design, reliability, and abuse engineering teams.
