Senior Opto-Mechanical Engineer (Large Optics Structures)

Join our team as a Senior Opto-Mechanical Engineer, where you will be responsible for developing mounting and support methodologies for large, segmented, and lightweight mirrors used in deep-UV, high-energy laser beam transport. You will lead the design and analysis of the supporting structures, perform structural-thermal-optical performance analysis, and define vibration isolation and damping strategies. This is a hands-on role that requires a strong background in opto-mechanical engineering and experience with large optics.

• Développer des méthodologies de montage et de support pour de grands miroirs segmentés et légers utilisés dans le transport de faisceaux laser.
• Architecturer et concevoir les structures de support, optimiser la rigidité, la stabilité thermique et la résistance aux vibrations.
• Effectuer des analyses de performance structurelle-thermique-optique, définir des stratégies d'isolation et de damping.

• Ability to build tolerance stack-ups for optical sensitivity analysis and a clear understanding of how mechanical tolerances translate into optical tolerances
• Experience: 10+ years of opto-mechanical engineering experience, including full lifecycle ownership (concept, analysis, procurement, assembly, test) of precision optical hardware
• Education: B.S. in Mechanical Engineering, Optical Engineering, or a related field
• Demonstrated experience designing mounts and support structures for large optics (meter-class apertures), including truss or weldment structures for support and adjustment
• Understanding of gravity-induced sag and print-through and the mount strategies used to control them
• Practical knowledge of machining, welding, and fabrication processes and design for manufacturability for large precision structures
• Comfort working in cleanroom, high-vacuum, and high-voltage environments
• Experience designing and characterizing optical mounts in the presence of PSD-defined base and external vibration, including quantifying resonant modes and harmonics and correlating FEA to modal test data
• Experience implementing alignment references and integrating optical subsystems containing flat, powered, and off-axis mirrors
• Fluency in 3D CAD (NX preferred; SolidWorks or Creo acceptable) and in creating drawings using GD&T per ASME Y14.5
• Strong written and verbal communication and a track record of clear technical documentation
• Experience creating and maintaining interface control documents
• Strong FEA skills (static, modal, random vibration, thermal) in standard tools such as Ansys, Abaqus, or Nastran, and the ability to fit and decompose deformed optical surfaces (e.g., Zernike or rigid-body fits) into figure and pointing errors
• Working knowledge of athermal design: CTE matching, thermal gradient and soak effects on figure and alignment, and low-expansion material selection
• M.S. or Ph.D. in Mechanical Engineering, Optical Engineering, or a related field
• Experience with segmented mirror arrays or large-format mirrors greater than 1 m, including multi-DOF mounts and array-level alignment
• Design, fabrication, or optimization of lightweight mirror substrates
• Active mount pointing and alignment recovery, including slow and fast steering mirrors
• Experience with high-energy laser systems, particularly in the deep UV, and with laser-induced damage considerations for coated optics
• Hands-on experience with optical fabrication and assembly techniques, including adhesive bonding of optics
• Background in large telescope, lithography, or high-energy laser facility opto-mechanics
• Experience with vibration isolation systems and facility or slab dynamic characterization
