Mechanical Engineer / Senior Mechanical Engineer, Xcimer

• 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
• 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

Desirable

• 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
• 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
