Principal Test Engineer – Manufacturing Test Operations

Job Overview

This is a senior leadership opportunity to drive manufacturing test operations for next-generation semiconductor products across high-performance segments including Cloud, Infrastructure, and Automotive.

As a Principal Engineer, you will lead the definition and execution of test strategy for complex, high-performance SoCs while remaining highly hands-on with Advantest V93K (93K EXA Scale) platforms and SmarTest (SMT7/SMT8) environments.

A key aspect of this role is end-to-end ownership of manufacturing test, including lab bring-up and infrastructure development from scratch, enabling characterization and production readiness. You will work closely with OSAT partners to ensure smooth production ramp, yield optimization, and operational excellence.
