Mechanical Test Engineer, Battery and Power Electronics

The role

You will develop validation systems and test infrastructure to ensure battery and power electronics hardware is safe, reliable, and manufacturable. This involves designing, building, automating, and operating systems that validate products throughout development, qualification, manufacturing, and field support.

What you will do

• Design and build mechanical, electrical, and software-integrated test equipment.
• Develop validation strategies for functional, environmental, vibration, thermal, abuse, reliability, and durability testing.
• Design custom fixtures, instrumentation, wiring harnesses, and data acquisition hardware.
• Develop automated test sequences, data collection, and analysis workflows.
• Plan and execute battery characterization, vibration, thermal cycling, shock, crash, and electrical validation campaigns.
• Own test readiness reviews, equipment qualification, and laboratory safety documentation.
• Analyze failures using instrumentation, teardown inspections, and root cause analysis.
• Partner with cross-functional teams to translate engineering questions into validation plans.
• Develop scalable test infrastructure for engineering, manufacturing, and supplier qualification.
• Support supplier qualification and failure investigations for externally manufactured hardware.

Required qualifications

• Experience developing validation systems, production test equipment, or engineering test infrastructure for complex electromechanical products.
• Experience designing and building custom test equipment, fixtures, instrumentation, or automated validation systems.
• Strong mechanical design skills using NX, SolidWorks, or equivalent CAD software.
