Introduction to the jobTheManufacturing –Technical Support Senior CompetencyEngineer (Optics) plays a critical technical leadership role withinYieldStar(YS) manufacturing operations inLinkou, with a primary focus on optical systems, optical modules, and optical sensingbehavior.This role serves as the key technical authority for optics-related system behavior, troubleshooting strategy, and technical decision-making across mature ASML product portfolios, includingYieldStar, PAS5500, ReticleHandler (RH), andXT.The position focuses on system-level optical performance, optical sensing, calibration robustness, optical alignment sensitivity, and optical module behavior that directlyimpactfactory output, quality, and deliveryperformance.Acting as a technical control tower, this role integrates inputs from Development Engineering (DE), Manufacturing, and Technical Support teams to drive structured problem-solving, manage high-impact and recurring disturbances, and deliver clear, management-ready technicalconclusions.This role does not manage direct reports, but carries strong technical ownership, influence, and decision responsibility in complex, cross-functional, and escalation-drivenenvironments.Role and responsibilitiesTechnical Leadership Optics-Focused System Decision-MakingLead 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 ManagementOwn high-impact, recurring, and long-duration optics-related disturbances acrossYieldStarmanufacturing lines.Coordinate cross-functional resources including DE (Optics, Mechatronics, Software Control), ManufacturingEngineering, Technical Support Engineers, and Production Engineers.Identifyescalation triggers, risk exposure, and containment actions to minimize machine downtime and preventissuerecurrence.Structural Analysis BKMDeployment (Optics)Perform structural analysis toidentifysystemic gaps in optical design, calibration methods, diagnostics, or manufacturing execution.Drive the development, validation, and deployment ofBest-KnownMethods (BKM) related to optical alignment, calibration, sensing, and diagnostics across product lines.Ensure optics-related improvements are standardized and sustainablyimplemented.Technical Coaching Competence DevelopmentProvide technical guidance and coaching on optics-related troubleshootingmethodologyand 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 CommunicationDeliver concise, management-ready technical reports, escalation packages, and decision summaries focused on optics-related risks and impacts.Represent manufacturing opticsexpertisein English-based escalation and alignment meetings with global stakeholders.Ensure transparent, professional communication across production, engineering, and supportorganizations.Cross-LineIntegration Factory Target SupportLeverage optics insights fromYieldStarmanufacturing 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 systemrobustness.Required QualificationsEducationBachelor’s degree or above in Engineering, with strong relevance to:Optics / Optical EngineeringApplied Physics (optics-focused)Photonics / Electro-Optical EngineeringElectrical Engineering with strong optics exposureExperience5~8+ 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 environmentsExperience acting as a technical focal point, project lead, or senior technical contributor responsible for cross-team alignment and technical decision-making.Skills CompetenciesStrong 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 QualificationsExperience with YieldStar, PAS5500, Reticle Handler, XT, or similar semiconductor equipment platforms.Background in DE optics roles or experience bridging RD 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.Other InformationShift work:This role supports multiple manufacturing teams with different shift patterns.During the interview process, both teams will participate in the
