Introduction to the job
The Manufacturing – YieldStar (YS) Technical Support Engineer (Optics) plays a critical role in ensuring stable and efficient production performance of YieldStar systems in Linkou. This position acts as a technical problem owner within defined scope, responsible for driving structured troubleshooting, restoring system performance, and supporting continuous improvement in a high-pressure manufacturing environment.
Unlike domain-specific roles, this position focuses on broad system-level understanding, including optics, sensors, control systems, and mechatronics interactions within YieldStar platforms. The engineer is expected to bridge execution and technical analysis, working closely with Manufacturing, Production Engineering, and Development & Engineering teams to drive effective problem resolution.
In addition to resolving operational disturbances, this role contributes to system understanding, problem prevention, and capability building, serving as a key talent pipeline toward advanced technical roles within YieldStar manufacturing.
Candidates with optics-related backgrounds will have strong opportunities to leverage their expertise in optical diagnostics, calibration, measurement performance analysis, and optical behavior troubleshooting, while further developing broader system-level knowledge across YieldStar platforms.
