No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
This is a senior position in an experienced department that is growing to support the company’s expansion plans. You will work alongside technicians, engineers and scientists on system builds, maintenance and upgrades, and the quality of the assembly work is what the rest of the machine depends on. The role is based in Oxford and is five days a week on site, because the work is hands on in the laboratory and the workshop.
Key Responsibilities
- Build and commission optical and laser assemblies.
- Support system maintenance and upgrades with engineers and scientists.
- Handle high precision and delicate components, using microscopes where required.
- Follow mechanical and electrical drawings and work instructions, document the work and test equipment before shipment.
- Maintain a safe laboratory and workshop environment when working with lasers and optics.
What You'll Need
- Practical laboratory experience with lasers and optics, precision assembly, free space optical alignment and fibre coupling.
- Comfortable taking responsibility for tasks with minimal supervision.
- Experience testing high technology equipment before shipment.
- A Bachelors or Masters in an optics related discipline, an Advanced or Modern Apprenticeship at Level 3 in Engineering, and an HNC at Level 4 in Engineering are all useful routes in, and an equivalent combination of education and practical experience is just as welcome.
