Senior Product/Test Engineer

Senior Test Engineer - NPI Test & DFT Methodology

Role Summary

We are looking for a Senior Test Engineer to join our Automotive MCU NPI Test Engineering organization.

In this role, you will be responsible for defining and delivering robust manufacturing test solutions from product concept through production ramp. You will lead test strategy development, DFT engagement, ATPG integration, silicon bring-up, characterization, qualification, and production release for complex automotive MCU products.

As the DFT and test methodology subject matter expert, you will work closely with Design, DFT, Product Engineering, Validation, Reliability and Manufacturing teams to ensure optimal test coverage, quality, test cost, and time-to-market.

The successful candidate is expected to provide technical solution across multiple concurrent NPI programs while mentoring engineers and driving best-in-class test methodologies.
