Senior Electrical Hardware Test Engineer, Energy Storage

The role

You will design and execute validation tests on high-voltage power electronics components and assemblies. You will debug hardware, design custom PCBAs, and develop Python tools for test automation and data analysis.

What you will do

• Design, set up, and execute validation tests on high-voltage power electronics components and assemblies
• Read and work directly from schematics, Altium layouts, and datasheets
• Debug and diagnose hardware hands-on
• Design, fabricate, and source custom PCBAs
• Specify and build supporting test infrastructure
• Develop and maintain test automation and data analysis tools using Python
• Collaborate with cross-functional teams to generate FMEAs and test plans
• Analyze complex test data and drive design and process enhancements

Required qualifications

• 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 (400–2000VDC and 480–800VAC)
• Proficiency with Altium or similar EDA tools
• Fluency reading schematics, layouts, and component datasheets
• Comfort at the bench with oscilloscopes, probes, and general lab instrumentation
• Working knowledge of power conversion — switching topologies, gate drive, isolation, protection, and thermals
• Demonstrated experience with root cause and failure analysis
• Proficiency in object-oriented programming
• Excellent communication and interpersonal skills

Nice to have

• Python preferred
