## About the role

We are looking for a highly capable Mechanical/ Optomechanical Engineer to join our team and take the lead in designing and optimizing large, ultra-stable optical mounts for high-energy, ultra-short-pulse laser systems. This role requires expertise in mechanical design, vibration and thermal analysis and precision kinematics. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Proven experience designing large, stable optical mounts or optomechanical assemblies for high-energy laser systems
- Strong understanding of precision mechanical design and kinematics, including spatial and angular degrees of freedom, stiffness, backlash, repeatability, and alignment
- Experience with thermal and thermo-mechanical simulation, including temperature gradients, thermal expansion, heat transfer, cooling concepts, and resulting structural deformation
- Good understanding of engineering materials and their relevant properties, including CTE, stiffness, thermal conductivity, dimensional stability, and vacuum compatibility
- Proficiency in CAD and mechanical modeling (e.g. SolidWorks, Inventor or similar), including thermal and vibrational analysis techniques
- Ability to translate optical requirements into mechanical, thermal, positioning, and stability requirements and work effectively with optical engineers, physicists, controls engineers, and manufacturing teams
