xLight is building the next-generation light source for semiconductor manufacturing — harnessing free-electron laser technology to deliver an industrial-grade, continuously operating light source for advanced patterning, metrology, and inspection.

About the Role

We're growing our team and looking for a Mechanical Engineer with Control Account Management (CAM/EVMS) experience to lead accelerator component designs and own cost/schedule performance on our accelerator program.

Responsibilities

• Contribute to the mechanical design of accelerator components taking concepts from feasibility through commissioning.
• This includes CAD, GD&T, FEA/CFD analysis, prototype testing, and cross-functional collaboration across mechanical, optics, electrical, physics, and systems teams.
• As a Control Account Manager, you'll own discrete work packages within our EVMS framework (ANSI/EIA-748 / DOE Order 413.3B), including:
• Developing and baselining Control Account Plans (CAPs)
• Tracking and reporting monthly EV metrics (BCWS, BCWP, ACWP, SPI, CPI)
• Preparing Variance Analysis Reports (VARs) with root cause and corrective actions
• Developing ETCs and EACs; managing budget and schedule baselines
• Participating in IBRs, Monthly Performance Reviews, and DOE project audits
• Coordinating change control through the project BCCB

Qualifications

• Staff Engineer – P4: BS + 8 yrs or MS + 6 yrs in Mechanical Engineering or related field
• Cross-functional technical leadership experience
• Familiarity with EVMS on DOE or major capital projects
• Senior Staff Engineer – P5: BS + 15 yrs or MS + 13 yrs in Mechanical Engineering or related field
• Substantial CAM experience on DOE projects (e.g., LCLS-II, APS-U, ALS-U, FRIB, SNS)
• Direct experience interfacing with DOE project offices and Federal Project Directors

Required Skills

• Synchrotron beamline or scientific instrumentation experience
• Semiconductor capital equipment background
• Primavera P6 proficiency
• AACE (EVP, CCP, PSP) or PMP / PMI-SP certification
• Cryomodule assembly and commissioning at a national lab

Pay range and compensation package

• Competitive compensation + equity (stock options)
• Full benefits: medical, dental, vision, life insurance
• 401(k) with company matching
• Flexible work: hybrid and remote options supported
• The chance to build something genuinely new in photon science and semiconductor manufacturing
