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?


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 scientists, software & hardware engineers, application development engineers, and senior product technology process engineers.

KLA is ramping its fastest-growing new research & development center in Ann Arbor, MI, and we're hiring the best talent for it.  In Ann Arbor we're developing product equipment, test centers, and the software and AI algorithms that power the cutting-edge capabilities KLA is recognized for. 

Central Engineering is KLA's largest engineering organization comprised of 9 Centers-of-Excellence (CoE) in various disciplines applied across all product groups in the company, and across all global regions. These CoE include Handling & Automation, Precision Motion Control, Sensors & Image Acquisition, Platform Design, and Packaging Engineering, among others. Talent includes over 1,000 engineers across global centers in Israel, China, India, and the US. Each CoE contributes not just talent and deliverables per discipline toward product programs, but also subject matter expertise, best practices, roadmaps, specialized facilities, apparatus, models, and analytics. These differentiate KLA not only in WHAT we do, but also in HOW we do it. 


In this role successful candidates will be responsible for:

  • Design, modeling, analysis and tolerancing of complex optical systems with specific characteristics to fit requirements within specified physical limits of precision optical instruments using state-of-the-art software tools including sequential and non-sequential ray tracing software (Zemax, CODEV), MATLAB, LightTools (or equivalent).

  • Design and/or specify state-of-the-art components and modules, such as lasers, LEDs, optical fibers, cameras, detectors, anamorphic beam shaping sub-systems, lens systems, telescopes, acousto-optical devices
  • Alignment and optimization of optical modules & systems
  • Trouble shooting and failure analysis of optical modules & systems
  • Design of inspection instruments to test and qualify optical components, modules and system
  • Work efficiently in cross-function teams to integrate optical system in overall final product
  • Collaborate with vendors to develop customized optical components and modules
  • Documentation, alignment and trouble-shooting of optical systems to transfer product to manufacturing and field service
  • Work on multiple projects in parallel


  • Education and experience in optical module & system design
  • Background in designing, tolerancing and testing of optical systems and modules incl. straylight analysis
  • Experience in assembly and alignment of optical systems and modules
  • Basic knowledge of manufacturing of optical components
  • Be able to work in a multi-discipline and multi-culture global organization
  • Be flexible and adaptive to adjust project focus based on changes of business priorities
  • Excellent verbal and written communication skills
  • Must be self-driven and a strong team player
