- Create and maintain 3D CAD models, manufacturing and assembly drawings, bills of materials and documentation, including GD&T and tolerance analyses
Materials & Suppliers
- Choose materials, components, processes and suppliers, with attention to precision, cleanliness, vacuum compatibility, thermal stability and vibration
- Coordinate manufacturing and procurement, review supplier drawings and quotes, solve fabrication issues and inspect delivered parts
Assembly & Commissioning
- Plan and carry out mechanical assembly, alignment, integration and functional testing in laboratories and experimental facilities
- Support on-site installation, commissioning, troubleshooting and design improvements with scientists, electrical engineers and controls teams
- Keep configuration control, design revisions, verification records and clear handover documents
Qualifications
Education
- Bachelor’s or Master’s degree in mechanical engineering, mechatronics, precision engineering or a related field
Experience & Skills
- Practical experience designing and delivering precision mechanical devices, instruments or optomechanical assemblies
- 3D CAD and production drawings, preferably Autodesk Inventor or SolidWorks, including GD&T, tolerance stack-ups and design for manufacturing and assembly
- Understanding of machining, fabrication, materials, fasteners, bearings, alignment methods and metrology
- Hands-on support of manufacturing, assembly, testing, installation or commissioning
- Able to coordinate with suppliers and multidisciplinary teams
What Sets You Apart
- Experience with scientific diagnostics, optical instruments, laser facilities, beamlines or experimental physics equipment
- Design for high vacuum, cleanrooms, low vibration, thermal stability or micron-level alignment
- Knowledge of motion stages, actuators, kinematic mounts, FEA and acceptance testing
