onsemi is seeking a Reliability Lab Engineer to support reliability testing, device qualification, and lab operations for cutting-edge Wide Bandgap semiconductor technologies, specifically Gallium Nitride (GaN) and Silicon Carbide (SiC). This is a hands-on engineering role focused on accelerating the adoption of high-efficiency power semiconductors in automotive and industrial applications.
In this position, you will design custom test circuits, load boards, and hardware test platforms tailored for GaN and SiC device reliability testing. You will operate, maintain, and troubleshoot reliability lab stress tools including HTOL (High Temperature Operating Life), ELFR, HAST (Highly Accelerated Stress Test), and high-voltage/high-temperature testing equipment. Your responsibilities include executing rigorous stress test protocols to evaluate device reliability, ruggedness, and long-term electrical stability, then collecting, cleaning, and analyzing test data using statistical analysis tools to identify failure mechanisms and degradation trends.
You will collaborate cross-functionally with Product Development Engineering (PDE), design, process, and quality teams to support root-cause analysis and corrective actions. You will maintain precise documentation of test setups, run logs, calibration records, and equipment maintenance while ensuring compliance with JEDEC, AEC-Q101, and AQG industry standards.
