Team Lead Principal Test Engineer (f/m/div)

As a Team Lead and Principal Test Engineer, you will head a team of Test Development Engineers, driving complex test challenges from concept through NPI release to high-volume manufacturing for industrial analog and mixed-signal ICs. You will collaborate with other related Product and Test Engineering teams as well as cross-functional teams. Lead and develop the team by setting a clear vision and priorities, conducting regular 1:1s, building capabilities, and fostering an inclusive, high-trust culture Own test strategy and execution: Test concept definition, Design for Test (DfT) guidelines, bring-up, characterization, correlation, qualification, and release to production Guide cost- and resource‑efficient development of automated test solutions for complex analog/mixed‑signal circuits on Advantest V93000 and Teradyne Eagle ETS‑800,88 Drive test program implementation for power‑related functions (e.g., Protection-ICs, gate drivers, SMPS, ADC/DACs), ensuring safe and robust measurement methods Oversee test hardware development, including loadboards and probe cards Define test specification, in close collaboration with Concept, Design, and Product Engineering, ensuring traceability from requirements to test coverage Ensure test packages are delivered on time and at quality by managing resources, risks and gates, and drive structured problem solving (e.g. 8D) for test-related issues Promote the practical use of AI tools and methodologies in daily work You are team and results oriented, able to set clear priorities across multiple projects and stay focused on long term goals. You communicate openly, handle pressure constructively, and cultivate a quality mindset—sharing information comprehensively and effectively.
