There is never a dull moment with us.The KLA Services team headquartered in Milpitas, CA is our service organization that consists of Service Sales and Marketing, Spares Supply Chain management, Field Operations, Engineering, Product Training, and Technical Support. The KLA Services organization partners with our field teams and customers in all business sectors to maintain the high performance and productivity of our products through a flexible portfolio of services.We are looking for a highly skilled hands-on engineer with experience supporting and troubleshooting complex semiconductor capital equipment in a fab environment. This role is ideal for someone who enjoys working directly with tools in the field, diagnosing issues at the system and component level, and driving solutions that keep production running.As a Customer Support Engineer, you will be the technical expert on-site—partnering closely with customers to resolve equipment issues, optimize performance, and minimize downtime in a cleanroom manufacturing environment.What You'll DoTroubleshoot and repair advanced semiconductor equipment at customer sites, including both system-level and board/component-level diagnosticsPerform root cause analysis on complex electro-mechanical, vacuum, chemical, and process-related issuesWork hands-on to restore tool performance quickly and safely, minimizing fab downtimeEvaluate equipment behavior and identify issues that may stem from process conditions (e.g., contamination, leaks, or environmental factors)Make critical decisions in the field, including recommending tool shutdowns for safety or yield protection when neededSupport installations, upgrades, and modifications of equipment in partnership with installation teamsDocument service activity, recurring issues, and corrective actions to support continuous improvementManage spare parts inventory and support service-related administrative tasks (reports, quotes, etc.)Collaborate with engineering teams to share knowledge and improve service strategiesProvide technical guidance to peers and assist with cross-training as neededWhat This Role Looks LikeSignificant time working on the factory floor or in cleanroom environments (50%+ travel/on-site)Independent, field-based role requiring strong problem-solving and ownership mindsetDaily communication with internal teams during critical situations (especially tool-down events)Work that goes beyond scripts or standard procedures—requiring real-time troubleshooting, technical judgment, and hands-on expertiseWhat We're Looking For5+ years of experience supporting semiconductor capital equipment (or similarly complex manufacturing equipment)Proven ability in hands-on troubleshooting of electro-mechanical systems (not IT/software support)Experience working in cleanroom/fab environments strongly preferredStrong understanding of system-level diagnostics, not just component swapsAbility to work independently under pressure and solve complex, non-routine problemsWhy This Role Stands OutThis is not an IT support or help desk role. It's a true field engineering position where you'll apply your technical expertise to solve complex equipment challenges, work directly on advanced tools, and play a critical role in keeping semiconductor manufacturing running.Minimum QualificationsMaster's Level Degree and related work experience of 3 years; Bachelor's Level Degree and related work experience of 5 years (or equivalent hands-on experience)KLA is proud to be an Equal Opportunity Employer.
