Job description

Develop cost-effective and high-efficiency test solutions for GaN and Silicon device families.

Create, debug, and release test programs on discrete testers and mixed signal ATE platforms. Lead the transitionof legacy platforms to new technology nodes.

Hardware Design & Requirements

Lead the design reviews and acceptance of high-performance test interface hardware provided by external vendors.

Design test hardware including load boards, probe heads, and sockets.

Define test hardware requirements based on device specifications and characterization data

Execution & Sustaining

Support New Product Introduction (NPI) through validation, release, and yield ramp activities.

Provide sustaining support for production products and test platforms.

Lead platform conversions and drive efficiency improvements across multiple ATE systems.

Technical Expertise

Apply knowledge of wide bandgap semiconductors, power devices, and analog measurement techniques.

Perform high-voltage and high-current testing safely and efficiently.

Use lab tools such as oscilloscopes, DMMs, spectrum analyzers, and ATE debugging utilities.

Cross-functional Collaboration

Partner with design, product, reliability, test, and operations teams to ensure smooth project execution.

Organize technical data and present findings for engineering and management teams.

Qualifications
