Mechanical Engineer / Senior Mechanical Engineer, Opto-Mechanics

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.
