About The Position

The Broadband Plasma (BBP) division is the market-leading optical inspection system used by logic, foundry, and memory customers to detect critical defects at advanced nodes. These tools combine broadband plasma technology with unmatched sensitivity and speed to support high-volume manufacturing. In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise. We are seeking a highly experienced Senior eBeam Systems Design Engineer to lead the design, modeling, optimization, and performance improvement of advanced electron beam systems used in next-generation semiconductor inspection and metrology platforms. This role requires a unique combination of deep theoretical expertise in electron optics, strong systems engineering capability, and hands-on experience working directly with complex eBeam columns and subsystems. The successful candidate will serve as both a designer and practical problem solver, leveraging simulation tools and real-world system observations to improve performance, reliability, and imaging capability. As a technical leader, you will independently drive high-impact projects, collaborate across multidisciplinary teams, and communicate complex technical concepts to engineers, scientists, and leadership stakeholders.
