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.

At xLight, 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.

We are seeking a Senior Structural Engineer to serve as the structural subject matter expert on a large-scale, technically complex campus infrastructure and accelerator facility program. Seismic design and accelerator equipment mounting and anchorage are critical elements of this project — the right candidate brings deep expertise in both and can independently evaluate structural designs for precision scientific equipment installations. This is a hands‑on engineering role requiring the ability to critically review designs, evaluate field conditions, and provide authoritative technical guidance to the design and construction teams.

• Lead structural design reviews at all milestones (30%, 60%, 90%, IFC) including foundations, framing, shielding walls, and equipment support structures
• Review and resolve structural submittals, RFIs, and change order requests with technical rigor
• Evaluate seismic design for the facility and all major equipment — seismic anchorage, bracing, and restraint of accelerator components, cryogenic systems, and precision instrumentation
• Review accelerator equipment mounting and support structures for compliance with vibration, tolerance, and alignment requirements
• Assess in‑house equipment mounting designs and anchorage details for scientific and accelerator hardware
• Review heavy equipment foundations, crane runway structures, and overhead lifting systems
• Evaluate vibration and settlement criteria for precision equipment and accelerator beamline systems
• Assess shielding wall and radiation vault structural design for compliance with requirements
• Evaluate contractor work‑in‑place for conformance with structural contract documents
• Identify structural design gaps, coordination conflicts, and specification deficiencies

• Support concept‑level structural assessments and feasibility studies
• Assist with development and tracking of owner structural requirements
• Identify and elevate structural risks in a timely manner

• Attend design and construction progress meetings as structural representative
• Maintain structural submittal logs and RFI registers
• Coordinate with geotechnical, civil, and MEP disciplines on interface requirements
• Represent the owner in structural‑related contractor and consultant meetings

• Reporting and stakeholder communication on structural matters

• Minimum BS in Structural or Civil Engineering required
• 8+ years of progressive structural engineering experience on complex facilities
• Experience on research facilities, industrial, or mission‑critical infrastructure programs
• Deep expertise in seismic design, equipment anchorage, and restraint systems per IBC, ASCE 7, and applicable standards
• Expe…
