Job Description/Preferred Qualifications
Join the Singapore-based Sustaining Engineering team as thetechnical projectowner for in-fab repair activity across KLA's 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.
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 team's 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.
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.
Minimum Qualifications
- Bachelor's or Master's 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.
Strong working knowledge ofboard level troubleshooting, precision motion control, vacuum, high-voltage, and complex electromechanical subsystems.
