Company Overview

Calling the adventurers ready to join a company that's pushing the limits of nanotechnology to keep the digital revolution rolling. At KLA, we're making technology advancements that are bigger—and tinier—than the world has ever seen.

Who are we?  We research, develop, and manufacture the world's most advanced inspection and measurement equipment for the semiconductor and nanoelectronics industries. We enable the digital age by pushing the boundaries of technology, creating tools capable of finding defects smaller than a wavelength of visible light. We create smarter processes so that technology leaders can manufacture high-performance chips—the kind in that phone in your pocket, the tablet on your desk and nearly every electronic device you own—faster and better. We're passionate about creating solutions that drive progress and help people do what wouldn't be possible without us.  The future is calling. Will you answer?


The Global Service Support Organization (GSS) 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 GSS 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. Our comprehensive services include: proactive management of tools to identify and improve performance; expertise in optics, image processing and motion control with worldwide service engineers, 24/7 technical support teams and knowledge management systems; and an extensive parts network to ensure worldwide availability of parts.

With over 40 years of semiconductor process control experience, chipmakers around the globe rely on KLA to ensure that their fabs ramp next-generation devices to volume production quickly and cost-effectively. Enabling the movement towards advanced chip design, KLA's Global Products Group (GPG), which is responsible for creating all of KLA’s metrology and inspection products, is looking for the best and the brightest research scientist, software engineers, application development engineers, and senior product technology process engineers.

The Surfscan group includes a team of engineers, technology development, apps engineers and product marketing focused on technology that enables wafer, IC and equipment manufacturers to develop, qualify and monitor their process tools. Defects and process non-uniformities detected on Surfscan equipment allow for early identification of yield excursions.

The flagship Surfscan products include the SPx platforms for wafer surface quality and wafer defect inspection tools and systems for inspection of polished wafers, epi wafers and engineered substrates during the wafer fabrication process.



Primary Responsibilities:

Tech Support Engineers (TSE) independently respond to issues where first-line product support has been unable fix problems in malfunctioning equipment. Work on more difficult problems requiring in-depth system knowledge and understanding of operating principles. Exercise judgment within broadly defined practices and policies in selecting methods, and techniques for achieving results. If the depth of technical understanding requires, consults with other engineering teams, and hosts meetings with multiple teams to discuss the technical issues and figure out the best course of action. Clearly document troubleshooting processes and technical findings to generate service reports.

Provide highly visible customer support through the performance of on-site installation, as well as leading all aspects of any vital diagnoses, troubleshooting, service, and repair of complex equipment and systems. Checks out and approves operational quality of system equipment. Responsible for tool customization, testing & qualification prior to shipment customer acceptance testing and obtain customer or account shipment approval.

Additional responsibilities may include:

Reporting design, reliability and maintenance problems to the appropriate engineering or manufacturing organization. Detailing system problems and working with Service Organization Sustaining Engineering on Continuous Improvement Project (CIP) opportunities. Training of KLA and non KLA personnel. Develop and document new troubleshooting procedures and Best Known Methods (BKMs). Develop written procedures and training material. Act as Technical Support representative for new product development. Backfill or over support for Field Service Engineers.
