KLA Careers

Staff Sensor Characterization Engineer

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 Office of the Chief Technology Officer (CTO) plays a critical role in developing advanced long-range technology in collaboration with product divisions and strategic marketing, working on future technology like light sources, lasers, and sensors. We are engaged in the research and development process, and once the technology is mature, we partner with product engineering groups who then build products based on the technology we’ve developed.

The Office of the CTO also provides technical input into KLA’s strategic planning process, program reviews and Product Life Cycle (PLC) phases. We provide our broad technology expertise and cross-division experience to ensure we leverage the collective knowledge within our company.



As a talented electrical design engineer, this candidate will be responsible for developing novel, low-noise, high-speed UV image sensors and the associated sensor characterization solutions. The ideal candidate would be a highly motivated individual contributor that has the vision and initiative to provide technical leadership on the assigned sensor development projects.
