Introduction to the job 

The Manufacturing – Technical Support Senior Competency Engineer (Optics) plays a critical technical leadership role within YieldStar (YS) manufacturing operations in Linkou, with a primary focus on optical systems, optical modules, and optical sensing behavior. This role serves as the key technical authority for optics-related system behavior, troubleshooting strategy, and technical decision-making across mature ASML product portfolios, including YieldStar, PAS5500, Reticle Handler (RH), and XT. 

The position focuses on system-level optical performance, optical sensing, calibration robustness, optical alignment sensitivity, and optical module behavior that directly impact factory output, quality, and delivery performance. 

Acting as a technical control tower, this role integrates inputs from Development & Engineering (D&E), Manufacturing, and Technical Support teams to drive structured problem-solving, manage high-impact and recurring disturbances, and deliver clear, management-ready technical conclusions. 

This role does not manage direct reports, but carries strong technical ownership, influence, and decision responsibility in complex, cross-functional, and escalation-driven environments. 

Role and responsibilities 

Technical Leadership & Optics-Focused System Decision-Making

• Lead optics-related technical assessments during daily passdown, DRB (Disturbance Review Board), and escalation meetings. 

• Serve as the technical decision owner for complex optics-related issues, including imaging behavior, illumination stability, sensor accuracy, and calibration performance. 

• Consolidate technical findings, risks, and recommendations into clear conclusions to support management alignment and operational prioritization. 

Issue Ownership & Troubleshooting Management 

• Own high-impact, recurring, and long-duration optics-related disturbances across YieldStar manufacturing lines. 

• Coordinate cross-functional resources including D&E (Optics, Mechatronics, Software & Control), Manufacturing Engineering, Technical Support Engineers, and Production Engineers. 

• Identify escalation triggers, risk exposure, and containment actions to minimize machine downtime and prevent issue recurrence. 

Structural Analysis & BKM Deployment (Optics) 

• Perform structural analysis to identify systemic gaps in optical design, calibration methods, diagnostics, or manufacturing execution. 

• Drive the development, validation, and deployment of Best-Known Methods (BKM) related to optical alignment, calibration, sensing, and diagnostics across product lines. 

• Ensure optics-related improvements are standardized and sustainably implemented.

Technical Coaching & Competence Development 

• Provide technical guidance and coaching on optics-related troubleshooting methodology and system-level behavior understanding. 

• Act as a technical reference for optics topics, supporting peers and management teams in complex decision scenarios.

• Strengthen cross-line optics competence through knowledge sharing and structured problem-solving practices.

Operational Alignment & Technical Communication 

• Deliver concise, management-ready technical reports, escalation packages, and decision summaries focused on optics-related risks and impacts. 

• Represent manufacturing optics expertise in English-based escalation and alignment meetings with global stakeholders. 

• Ensure transparent, professional communication across production, engineering, and support organizations.

Cross-Line Integration & Factory Target Support 

• Leverage optics insights from YieldStar manufacturing lines to prevent repeated disturbances across systems and factories. 

• Respond rapidly to customer feedback, quality notifications, and urgent optics-related production issues. 

• Ensure all technical decisions align with factory strategy, quality standards, and long-term system robustness. 

Required Qualifications 

Education 

• Bachelor’s degree or above in Engineering, with strong relevance to: 

• Optics / Optical Engineering 

• Applied Physics (optics-focused) 

• Photonics / Electro-Optical Engineering 

• Electrical Engineering with strong optics exposure

Experience 

• 5~8+ years of experience in semiconductor, electronics, or precision equipment industries. 

• Strong background in one or more of the following optics-related domains: 

• Optical module integration, alignment, or calibration. 

• Optical sensing, imaging systems, illumination paths, or interferometric principles. 

• Troubleshooting optics-related system behavior in production or development environments 

• Experience acting as a technical focal point, project lead, or senior technical contributor responsible for cross-team alignment and technical decision-making.

Skills & Competencies 

• Strong system-level understanding of optical behavior and its interaction with mechanical, electrical, and control systems. 

• Proven ability to structure complex problems, assess risk, and drive technical decisions under production pressure. 

• Excellent English communication skills for escalation meetings, technical reporting, and stakeholder alignment. 

• Data-driven mindset with experience analyzing production or system data (specific tools not mandatory). 

• Proactive, ownership-driven, detail-oriented, open-minded, with strong logical reasoning capability.

Preferred Qualifications 

• Experience with YieldStar, PAS5500, Reticle Handler, XT, or similar semiconductor equipment platforms. 

• Background in D&E optics roles or experience bridging R&D and manufacturing environments. 

• Familiarity with optical calibration methods, sensor characterization, or optical diagnostic workflows. 

• Exposure to structured RCA, engineering change processes (ECN), or reliability improvement initiatives. 

• Experience mentoring or coaching engineers in technical problem-solving. 

• Lean / Kaizen mindset and experience driving continuous improvement.
