Senior Opto-Mechanical Engineer

About the role

We are seeking a highly motivated Opto-Mechanical Engineer to join our Photonics Systems engineering team. In this role you will design, develop, analyse and qualify precision optomechanical systems for optical interconnects, photonic devices and next-generation optical technologies.

Key responsibilities

• Design and develop precision optomechanical components, fixtures and assemblies, creating detailed 3D CAD models and mechanical drawings.
• Define and manage critical mechanical tolerances, alignment features and assembly interfaces to ensure robust optical performance.
• Perform tolerance stack-up analyses, mechanical, thermal, vibration and structural analyses, and establish manufacturing requirements for high-precision assemblies.
• Collaborate with optical engineers to develop packaging and integration solutions for lasers, detectors, optical fibres, micro-optics and photonic integrated circuits.
• Support prototype builds, verification testing, reliability testing and product qualification activities.
• Drive design-for-manufacturing and design-for-assembly improvements and work with suppliers to meet dimensional, cosmetic and performance specifications.

Required profile

• Bachelor’s, Master’s or Ph.D. in Mechanical Engineering, Optomechanical Engineering, Physics or a related discipline.
• Proven experience designing precision mechanical or optomechanical systems with micron-level accuracy and tight geometric tolerances.
• Strong understanding of GD&T, tolerance analysis and precision alignment features.
• Ability to manage multiple priorities in a fast-paced technology environment.

Required skills

• Proficiency with CAD tools such as SolidWorks, Creo or NX.
• Experience with precision manufacturing processes – CNC machining, micro-machining, injection molding, stamping.
• Familiarity with finite element analysis (FEA) and mechanical validation methods.
• Knowledge of GD&T and tolerance analysis techniques.

What we offer

• Pension scheme.
• Private medical and dental insurance.
• 28 days’ holiday plus bank holidays.
• Relocation support and visa assistance.
