Staff Electrical Engineer

Staff Electrical Engineer - Accelerator & Photon Systems Location: Hybrid - Newport News, VA or Naperville, IL About xLight xLight is building the world's most powerful laser to revolutionize semiconductor lithography, metrology, and for other critical applications. Our approach harnesses the power of free-electron lasers, building on accelerator technology in use globally at scientific user facilities. Extending this technology, we are developing industrial‑grade light sources, engineered for continuous operation, to meet the sophisticated demands of next‑generation patterning, metrology, and inspection applications. Join us in this new revolution. We hire exceptional talent — and exceptional means more than a strong résumé. How we achieve results is just as important as the results themselves, which is why attitude and character matter as much as technical skill. We believe great talent is widely distributed, not confined to a particular school or background. We seek individuals who demonstrate ownership, a spirit of collaboration, technical curiosity, and a genuine willingness to learn and grow — guided by our core values of Respect, Integrity, Creativity, and Engineering Excellence. We don't just hire for what someone can do today. We hire for who they are and who they are becoming. What We Need — and Why It Matters We are seeking an experienced Electrical Engineer to lead the design and optimization of complex electrical and control systems for electron accelerator components and photon transport systems. You will drive technical development of accelerator magnets, RF systems, cryogenic controls, detector electronics, and beamline instrumentation, collaborating with accelerator physicists and RF engineers on world‑class scientific facilities. This role offers the opportunity to work on cutting‑edge technology in a hybrid environment with flexibility across our Newport News, VA and Naperville, IL offices. What You’ll Do Lead design and development of electrical systems for electron guns, RF systems, and accelerating structures Design magnet power supplies, pulse systems, and high‑voltage distribution for accelerator components Develop control electronics for RF cavities, cryogenic systems, and beam diagnostics Perform electrical analysis and simulation (SPICE, ANSYS) for accelerator systems and photon diagnostics Design radiation‑hardened detector electronics and front‑end circuits for photon beamline diagnostics Develop specifications for beam position monitors, loss monitors, and photon diagnostics Ensure all designs meet accelerator safety standards, radiation requirements, and operational specifications Lead integration testing and troubleshooting of complex accelerator electrical subsystems Mentor junior engineers and provide technical guidance on accelerator projects What We Are Looking For Bachelor's degree in Electrical Engineering or Physics 8+ years of professional experience in accelerator or scientific instrument electrical engineering Deep expertise in magnet power supplies, RF control systems, and high‑voltage electronics Strong knowledge of particle accelerator systems, electron beam physics, and photon production Proficiency with electrical simulation tools (SPICE, MATLAB, ANSYS) and CAD software Experience with detector electronics, signal processing, and radiation tolerance requirements Strong problem‑solving and systems‑level thinking skills And If You Bring This — Even Better Master's or Ph.D. in Electrical Engineering or Physics Professional Engineer (PE) license or professional standing Experience with LCLS, SLAC, Fermilab, or comparable national laboratory accelerator projects Knowledge of cryogenic control systems and superconducting RF technology Experience with EPICS, LLRF systems, and accelerator control architecture Track record of leading technical teams and managing complex accelerator projects What You Can Expect from Us 100% Company‑funded health insurance for employee Company funded Life Insurance and disability insurance 401k contribution. 100% up to 3% of compensation, plus 50% match between 3% and 5%.
