Embark on a journey with us, where you can innovate for a future that we want to make smarter and greener, in a responsible and sustainable way. Our technology starts with you.

YOUR ROLE

• Define, develop, and standardize test platforms for Silicon Photonics and optical semiconductor devices within the ST test system ecosystem.
• Focus on test platform definition, characterization, benchmarking, and standardization activities rather than direct device development.
• Drive the selection, qualification, and deployment of test equipment, fixtures, interfaces, and supporting software used for optical semiconductor test flows.
• Establish robust and repeatable test methodologies to support device characterization, validation, production readiness, and long-term test consistency.
• Work closely with design, product engineering, manufacturing test, and quality teams to ensure test platform requirements are aligned with technical and operational needs.
• Support the harmonization of test approaches across sites, labs, and product lines to improve reuse, comparability, and scalability.
• Contribute to the definition of test specifications, measurement procedures, data formats, and reporting standards within the ST test system ecosystem.
• Analyze test data and measurement results to assess system performance, repeatability, accuracy, and correlation across platforms.
• Identify opportunities to improve test efficiency, reduce variation, and enhance automation and standardization.
• Support new technology introduction by defining test needs for emerging Silicon Photonics and optical semiconductor products.

Key Job Accountabilities
