Senior Electrical Test Engineer - Energy Products

Job Description

Job Responsibilities

• Design, build, and maintain scalable automated test frameworks (Python/Pytest, Robot Framework, LabVIEW/TestStand) for high-voltage power electronics systems  
• Own end-to-end Automated Test Equipment development — from instrument driver abstraction to test orchestration, data capture, and report generation  
• Design reusable, modular test libraries for hardware bench testing and production line screening — enabling teams to spin up new test coverage quickly  
• Develop firmware and embedded test code for custom test fixtures and HIL setups — microcontroller programming (STM32, ESP32, or similar) in C/C++ for sensor sampling, relay control, safety interlocks, and real-time data streaming back to the host framework 
• Design and build custom electrical test fixtures — schematic capture and PCB layout (Altium/Cadence) for breakout boards, signal conditioning, load banks, and HV switching matrices; specify connectors, contactors, and wiring harnesses for repeatable bench and production interfaces 
• Integrate test suites into CI/CD pipelines (Jenkins, GitHub Actions) so every firmware or hardware revision is automatically validated against a reliability baseline before it reaches review, and automate HALT, ALT, and burn-in sequences — sequencing climate/vibration chambers, power supplies, and measurement instruments as a single orchestrated system  
• Build automated data acquisition pipelines feeding directly into reliability dashboards to expedite lifetime reliability estimates, degradation trends, and pass/fail analytics refreshed in real time  
• Apply ML-assisted anomaly detection to identify unit outliers during production screening and predict failure signatures before they reach the field  
• Continuously drive design risk burndown to ensure product reliability and durability; perform reliability testing for industrial and residential energy power converters  
• Determine component and system-level test solutions that optimize product reliability and durability through DFMEA-based risk mitigations, resource planning, and program scheduling; facilitate failure analysis to understand root causes and drive resolution for failures originating in testing  

Job Requirements

• Degree in Electrical Engineering, or a related engineering discipline, or equivalent experience
• 3-10 years of hands-on experience in power electronics hardware design, design validation, hardware testing, mechanical system reliability, and durability testing 
• Knowledge of programming in scripting languages for test automation and data analysis/post-processing 
• Hands-on firmware development experience in C/C++ on bare-metal or RTOS microcontrollers (STM32, NXP, TI, ESP32, or similar) 
• Experience designing custom test fixtures and PCBs — schematic capture, layout, and bring-up of breakout boards, signal conditioning, and switching hardware 
• Experience working safely with high voltage equipment. Working knowledge of HV test instrumentation — hipot, IR, partial discharge, programmable AC/DC sources and loads, power analyzers 
• Experience specifying sensors for test instrumentation and utilizing data acquisition systems 
• Experience pro-actively owning and delivering test engineering projects within accelerated validation timelines 
• Proven ability to develop reliability and durability test setups, including environmental, mechanical, and electrical stress testing, highly preferred 
• Preferred to have experience of common automotive communication protocols (CAN, Ethernet)
