Senior Engineer/Scientist – X-ray Source Development

ZEISS Group•Dublin, CA

51d•$140,000 - $175,000

About The Position

With over 175 years of innovation, ZEISS is a global leader shaping the future of science and technology. From medical technology to semiconductor manufacturing and advanced research, our work drives real-world impact. Role Overview: We are seeking an accomplished engineer or scientist to lead the development of next-generation X-ray sources with a specialized focus on high voltage (HV) electronics, precision power delivery, and closed loop control systems. In this high-impact role, you will drive advanced electron optics and X-ray source design from simulation and research through prototyping and system integration, working cross-functionally to deliver breakthrough imaging performance and shape the future of X-ray technology.

Requirements

PhD or Master’s degree in Physics, Electrical Engineering, Materials Science, or a related field with specialization in electron optics, charged‑particle systems, vacuum devices, or radiation physics.
Demonstrated experience designing or modeling electron guns, electron‑optical lenses, or charged‑particle transport systems.
Hands‑on prototype development, experimental setup design, and quantitative characterization experience.
Strong communication skills and ability to collaborate across mechanical, electrical, software, manufacturing, and marketing teams.
Fluency in English is required, including technical terminology.
Ability to work with and understand the work product of team members from all R&D‑related departments, as well as Manufacturing and Marketing.
Exceptional communication skills to resolve technical challenges between mechanical, electrical, and software engineering; advanced development; manufacturing; and marketing.

Nice To Haves

Experience with X‑ray generation, X‑ray targets, high‑vacuum systems, or miniaturized radiation sources strongly preferred.
Experience in X‑ray tomography systems preferred.

Responsibilities

Design advanced electron gun architectures (thermionic, field emission) and high-performance lens systems to deliver a stable, high-brightness electron beam. Use state-of-the-art simulation tools to optimize beam quality and focus.
Analyze electron–target interactions to enhance X-ray output and efficiency. Develop novel target designs (e.g. rotating anodes, liquid metal, multi-layer) and cooling strategies to maximize flux and source longevity.
Lead prototyping of X-ray sources, including assembly and iterative testing of electron-optical assemblies and targets. Characterize performance (beam properties, spectra, flux, stability, thermal) to refine designs.
Collaborate with cross-functional teams to integrate X-ray sources into imaging systems, meeting resolution, contrast, and throughput requirements. Solve integration challenges (vacuum interfaces, alignment, high-voltage power, control systems) to ensure stable, long-term operation.
Drive projects from concept to completion with clear technical direction and milestone management. Mentor junior engineers and foster innovation to keep our X-ray source technology at the cutting edge.
