KLA Careers

Lead Research Scientist - Computational Physics

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?


KLA has always had a close relationship with physics and data.  Our optical and electron beam inspection and measurement tools use cutting edge physics models, both for hardware design and as part of their algorithms.  AI, including several traditional machine learning techniques and deep learning are routinely used to process this data to meet application requirements.


  • Research and innovate next-generation electromagnetic solvers and algorithms for semiconductor device and thin film metrology
  • Develop numerical models and algorithms using Matlab
  • Understand when the models and algorithms break down and develop testing procedures to validate assumptions in the models
  • Work with Advanced Development and Applications teams to confirm the feasibility of the new algorithms
  • Productize the new algorithms in C++/CUDA and integrate it into a C#-based software solution
  • Document the theory and implementation of the new algorithms, and give presentations both internally and externally regarding the work
  • Provide technical support during alpha and beta testing
  • Maintain new and existing algorithms and software solutions throughout the life-cycle of our tools
