Technical Lead (Sustaining Engineer)

Join the Singapore-based Sustaining Engineering team as thetechnical projectowner for in-fab repair activity across KLAs China customer base. Partner with field engineers to diagnose complex tool issues define root cause and deliver engineering solutions including plans of action (POAs) bills of materials (BOMs) and repair procedures that enable efficient first-time-right repairs in the fab. Effectively manage and prioritize multiple concurrent escalations across customers and tools.

Key Responsibilities

• OwnEscalation projectsfrom field in-fab repair teams in China; drive issues to closure with clear technical ownership.

• Manage multiple escalations and sites in parallel:Triage prioritize and sequence concurrent escalations across multiple customer sites based on customer impact tool downtime and business urgency for both own workload and the field in-fab repair teams activities.

• Project management:Plan and track escalation milestones dependencies and deliverables; coordinate cross-functional stakeholders (field HQ engineering logistics supply chain) to keep repair projects on schedule.

• Root-cause analysis:Investigate failure modes using tool logs repair history engineering data and field input; isolate mechanical electrical optical or software root causes.

• Direct field troubleshooting:Guide in-fab repair engineers step-by-step through diagnostics and corrective actions; provide real-time remote technical direction during live repair events.

• Author engineering deliverables:

• Plans of Action (POAs)outlining repair sequence risks and contingencies.

• Bills of Materials (BOMs)specifying parts tooling and consumables.

• Repair procedures and work instructionsvalidated for fab execution.

• Sustaining ownership:Partner with Design Engineering Reliability and Product Support to develop permanent fixes and engineering change orders for recurring field issues; drive continuous improvement of installed-base tool reliability.

• Knowledge capture:Document root causes solutions and lessons learned into the knowledge base so field teams can self-serve on recurring signatures.

• Cross-region coordination:Bridge between China field teams and HQ engineering translate field symptoms into engineering language and engineering solutions into field-executable steps.

• Travel:Certain travel required to customer sites in China and to HQ/engineering teams in the US to support escalations engineering reviews and knowledge transfer.

• Bachelors or Masters degree inElectrical Engineering Electronics Engineering Opto-Mechanical Engineering or related discipline.

• 5 years of sustaining engineering support engineering or senior field service experience on semiconductor capital equipment (inspection metrology or similar precision tools preferred).

• Hands-on troubleshooting experience at the board level ability to debug PCBAs using schematics oscilloscopes logic analyzers DMMs and signal-integrity tools; diagnose down to component level (power rails clocks digital/analog interfaces FPGA/DSP signals).

• Hands-on troubleshooting experience with opto-mechanical assemblies alignment calibration and repair of precision optical paths laser sources sensors/detectors mirrors stages and motion subsystems.

• Strong project management skills demonstrated ability to run multiple concurrent escalations/projects prioritize effectively under pressure set clear next steps for self and field teams and communicate status to stakeholders at all levels.

• Demonstrated ability to lead L4 escalations from triage through root cause to permanent corrective action.

• Strong working knowledge ofboard level troubleshooting precision motion control vacuum high-voltage and complex electromechanical subsystems.

• Proven ability to author clear POAs BOMs and repair procedures suitable for field execution in a cleanroom environment.

• Fluent written and spoken English; working proficiency in Mandarin strongly preferred for direct collaboration with China field teams.

• Prior experience supporting customers and field teams in China.

• Experience collaborating with Design Engineering on ECOs and reliability/sustaining improvement programs.

What Success Looks Like (First 12 Months)

• Owns the L4 queue for China in-fab repairs end-to-end; measurable reduction in escalation cycle time and repeat escalations.

• Concurrent escalations are clearly prioritized and tracked; field in-fab repair team receives unambiguous direction on what to work on next.

• POAs BOMs and procedures are consistently adopted by field teams with minimal rework.

• Trusted point of contact for both China field leadership and HQ engineering on in-fab repair matters.

• Measurable improvement in first-time-fix rate and MTTR on tools supported by the role.
