About The Position

KLA is seeking a hands-on Customer Support Engineer to support and troubleshoot complex semiconductor capital equipment in fab environments. The engineer serves as the technical expert on-site, partnering with customers to resolve equipment issues, optimize performance, and minimize downtime in cleanroom manufacturing settings. The role involves diagnosing issues at the system and component level, performing root cause analysis, and using technical judgment to restore equipment safely and efficiently. This is an independent, field-based position with significant time on factory floors or in cleanrooms and 50% or more travel/on-site work. The engineer communicates frequently with internal teams during critical situations, including tool-down events, and handles challenges that require real-time troubleshooting beyond standard scripts or procedures.
