Department: Engineering

Employment Type: Full Time

Location: Oxford

Description

We are seeking a highly motivated Opto-Mechanical Engineer to join our Photonics Systems engineering team. In this role, you will be responsible for the design, development, analysis, and qualification of precision optomechanical systems used in optical interconnects, photonic devices, and next-generation optical technologies.

Key Responsibilities

• Design and develop precision optomechanical components, fixtures, and assemblies for photonic and optical systems. 
• Create detailed 3D CAD models, mechanical drawings, and documentation using industry-standard CAD tools. 
• Define and manage critical mechanical tolerances, alignment features, and assembly interfaces to ensure robust optical performance. 
• Perform tolerance stack-up analyses and establish manufacturing requirements for high-precision assemblies. 
• Collaborate with optical and photonics engineers to develop packaging and integration solutions for lasers, detectors, optical fibers, micro-optics, and photonic integrated circuits. 
• Evaluate and select manufacturing processes and materials capable of achieving demanding dimensional and stability requirements. 
• Perform mechanical, thermal, vibration, and structural analyses to validate designs. 
• Support prototype builds, verification testing, reliability testing, and product qualification activities. 
• Drive design-for-manufacturing (DFM) and design-for-assembly (DFA) improvements for both low-volume and high-volume production. 
• Work with suppliers and manufacturing partners to ensure components meet critical dimensional, cosmetic, and performance specifications. 
• Investigate and resolve design, manufacturing, and reliability issues through structured root-cause analysis. 

Skills, Knowledge and Expertise

• Bachelor's, Master's, or Ph.D. in Mechanical Engineering, Optomechanical Engineering, Physics, or a related discipline. 
• Experience designing precision mechanical or optomechanical systems with tight dimensional and geometric tolerances. 
• Strong understanding of GD&T, tolerance analysis, precision alignment features, and manufacturing variation. 
• Demonstrated experience working with components and assemblies requiring micron-level accuracy and repeatability. 
• Proficiency with CAD software such as SolidWorks, Creo, NX, or equivalent. 
• Experience with precision manufacturing processes including CNC machining, micro-machining, injection molding, stamping, or related technologies. 
• Familiarity with finite element analysis (FEA) and mechanical validation methods. 
• Strong analytical and problem-solving skills. 
• Proactive and self-motivated, with a strong sense of ownership.  
• Delivery-focused and capable of managing multiple priorities.  
• Collaborative team player with strong communication skills.  
• Adaptable and eager to learn in a fast-paced technology environment 
• A proven track record of delivering optical products into production would be an advantage.  

Advantage  

• Experience in optical interconnects, optical transceivers, silicon photonics, photonic integrated circuits (PICs), optical packaging, or related photonics technologies. 
• Experience with active or passive optical alignment systems. 
• Familiarity with automated assembly and precision manufacturing environments. 
• Experience working with optical fibers, micro-optics, lasers, or detector integration. 

Benefits

• Pension scheme 
• Private medical & dental insurance 
• 28 days’ holiday + bank holidays  
• Relocation support 
• Visa support available
