• Perform real-time root-cause analysis on mechanical, electrical, and process issues directly at the factory.

• Participate in factory bring-up activities, including line readiness checks, equipment calibration, and process validation.

• Tune assembly parameters, test limits, and tooling configurations in collaboration with manufacturing engineers.

• Work closely with line operators and technicians to gather feedback, identify pain points, and implement process improvements.

• Execute hands-on experiments on the production line, including DOEs, process trials, and characterization builds.

• Collect on-line production data and analyze results to drive engineering decisions.

• Participate directly in bring-up, debugging, and maintenance coordination for automation, test stations, and AOI systems.

• Collaborate with equipment vendors during installation and troubleshooting.

• Perform physical teardowns, support failure analysis, and prepare reliability samples directly in the factory.
