Design, analyze, procure, assemble, align, and test precision opto-mechanical hardware for deep-UV, high-energy laser systems. Develop CAD models, GD&T drawings, tolerance stack-ups, FEA analyses, interface documents, and test plans. Collaborate across optical, controls, and systems engineering, support manufacturing and integration, and troubleshoot hardware in labs, cleanrooms, and manufacturing environments. Senior engineers lead subsystem designs, manage interfaces, and mentor junior engineers. The summary above was generated by AI Xcimer Energy builds on decades of research in Inertial Fusion Energy (IFE), combined with a groundbreaking new laser architecture, to accelerate the deployment of fusion power plants. Our mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. Xcimer has assembled a world-class team spanning tough tech, fusion science, and advanced manufacturing, with a proven track record of rapid execution. Supported by leading investors, Xcimer is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. Join us in powering a better world with inertial fusion! This is a full-time, onsite role based at our headquarters in Denver, CO. Every mirror, window, lens, and diagnostic in Xcimer's deep-UV laser system depends on mechanical hardware that holds it precisely, keeps it stable, and lets us align and maintain it. We are looking for mechanical engineers with sound design fundamentals and an interest in opto-mechanics to design, build, and test that hardware. You will work across the full lifecycle: requirements, concept, analysis, drawings, procurement, assembly, alignment, and test. This is a hands-on role where you will spend time in the optics labs, cleanrooms and manufacturing floors. We are hiring at multiple levels, from engineers with a few years of solid design experience who want to deepen their opto-mechanics expertise, to senior engineers who can lead subsystem designs and mentor others. Qualifications Design mirror mounts, window and lens mounts, opto-mechanical assemblies, optical benches, and structural supports for deep-UV, high-energy laser beam transport and diagnostics. Develop requirements with optical, controls, and systems engineers; run trade studies and document design decisions. Analyze designs with hand calculations and FEA (static, modal, thermal) to understand how mount stress, thermal gradients, gravity, and vibration affect optical surface figure and alignment. Produce detailed models in

NX, GD&T

drawings per ASME Y14.5, and complete drawing packages; release and control them through engineering change. Specify materials, finishes, and purchased components (stages, actuators, flexures, fasteners, vacuum hardware); work with machining and fabrication suppliers, and inspect and qualify hardware on receipt. Build tolerance stack-ups and connect mechanical tolerances to optical sensitivity budgets. Create and maintain interface control documents between optical mounts and adjacent mechanical structures. Assemble, align, and test opto-mechanical hardware in the lab and cleanroom, including bonding of optics and implementation of alignment references; develop and execute test plans. Support integration and troubleshooting on the laser system floor and feed lessons learned back into the design. Present work at design reviews and maintain clear technical documentation.

At the senior level:

lead the design of subsystems end to end, own interfaces with other disciplines, and mentor junior engineers.

Qualifications Education :

B.S. in Mechanical Engineering or a related field.

Experience :

4+ years of professional mechanical design experience with hardware you have designed built and put into use.

Sound mechanical design fundamentals:

statics, strength of materials, stiffness and deflection, thermal expansion, and materials selection. Proficiency in 3D CAD (NX preferred; SolidWorks or Creo acceptable) and in creating manufacturing drawings using GD&T per

ASME Y14.5.

Ability to build tolerance stack-ups and to verify designs with hand calculations. Familiarity with machining, sheet metal, and welding processes and with design for manufacturability and assembly.

Hands-on aptitude:

comfortable assembling, measuring, and testing hardware, and eager to spend time in the lab. Hands-on experience designing precision opto-mechanical hardware: kinematic or flexure mounts, optical benches, or alignment mechanisms. Solid FEA skills (static, modal, thermal) and experience using analysis to drive design decisions and validate them against test. Experience creating and maintaining interface control documents. Experience specifying and managing hardware through suppliers, and guiding or mentoring other engineers. Strong written and verbal communication, attention to detail, and the ability to work in a fast-paced, multidisciplinary team. Desired M.S. in Mechanical Engineering, Optical Engineering, or a related field. Experience with STOP (structural-thermal-optical performance) analysis and with modeling tools such as Ansys, Abaqus, or Nastran. Experience with cleanroom procedures, high-vacuum hardware, or high-voltage environments. Experience with active mount pointing and alignment recovery, including slow and fast steering mirrors. Experience with high-energy laser systems, particularly in the deep UV. Familiarity with thermal management of optical assemblies. Experience with laser, telescope, lithography, or precision instrument opto-mechanics.
