The impact you will make

As Optomechanical Engineer, you will design and deliver precision optical-mechanical assemblies for high-power laser facilities, with particular emphasis on beam transport and vacuum-compatible systems.

You will take ownership from concept and mechanical analysis through drawings, manufacturing, assembly, alignment, integration and commissioning, working closely with laser, optics, vacuum and controls specialists.

Your responsibilities

• Design precision optomechanical assemblies including mirror mounts, positioning stages, optical supports and beam transport structures for high-power laser systems.
• Develop vacuum-compatible mechanical designs, selecting suitable materials, seals, feedthroughs and motion mechanisms while considering cleanliness, outgassing and thermal performance.
• Produce 3D CAD models, detailed manufacturing drawings, GD&T, tolerance analyses, bills of materials and controlled engineering documentation.
• Perform or coordinate structural, modal, vibration and thermal analyses to ensure optical alignment, mechanical stability and positioning accuracy.
• Coordinate fabrication and supplier activities; support precision assembly, optical alignment, installation, integration, troubleshooting and commissioning.
  
  

What you bring

• Bachelor's or Master's degree in Mechanical Engineering, Optomechanics, Precision Engineering, Mechatronics or a related field.
• Proven experience designing precision optomechanical devices and mechanisms, ideally for high-power lasers or scientific instrumentation.
• Practical experience with vacuum-compatible mechanical systems and beam transport assemblies, including mechanical interfaces and alignment concepts.
• Strong skills in 3D CAD, manufacturing drawings, GD&T, material selection, precision machining and mechanical tolerance management.
• Hands-on experience with manufacturing follow-up, assembly, alignment, testing and commissioning in multidisciplinary technical environments.
  
  

What sets you apart

• Experience with high-energy laser beamlines, large optics, laser compressors or complex scientific facilities.
• Knowledge of high-vacuum or ultra-high-vacuum practices, vacuum cleanliness, motion feedthroughs and pumping-system interfaces.
• Experience with structural and thermal FEA, modal analysis, vibration isolation and stability-sensitive optical systems.
• Familiarity with motorized positioning stages, actuators, encoders and precision alignment methods.
• Independent problem-solving, practical engineering judgment and effective collaboration with optics, laser, vacuum and controls teams.
