Mechanical Design Engineer

The Department of Physics at the University of Oxford is seeking a Mechanical Design Engineer to join the Mechanical Design Group within the Oxford Physics Technical Excellence Centre (OPTEC). This role offers the opportunity to contribute directly to world-leading experimental physics projects, delivering precision-engineered solutions that support cutting-edge scientific research.

This post is fixed term for 3 years with a possible extension subject to funding.

You will design, analyse and deliver high-precision mechanical components and experimental equipment, much of which operates in Ultra-High and Extreme-High Vacuum environments. A growing focus of the role is the design and analysis of lightweight composite structures, particularly ultralight carbon-fibre systems for advanced physics experiments.

Working closely with academics, engineers, technicians and international collaborators, you will take projects from concept through detailed design, manufacture, testing and commissioning. The role combines hands-on engineering with technical leadership, design review and close interaction with in-house workshops and global research partners.

You will hold a degree in Mechanical Engineering, or equivalent professional experience, and have demonstrable experience in the design and analysis of precision scientific instrumentation. You will be highly proficient in 3D CAD (ideally CATIA V6 / 3DEXPERIENCE), with strong understanding of structural behaviour, low-temperature design and manufacturing best practice.

You will have practical experience with composite materials, including material selection, tooling and lay-up processes, and be comfortable applying FEA to validate complex designs. Strong communication skills are essential, with the ability to present technical information clearly to international collaborators and contribute to technical reports and publications.

Experience managing projects from concept to installation, mentoring junior engineers, and working in multidisciplinary research environments is required. Knowledge of UHV/XHV systems, vibration analysis or advanced composite design would be advantageous. Willingness to travel internationally for project work is essential.

This is a rare opportunity to see your engineering work directly enable globally significant scientific discoveries. You will work in a world-class technical environment with outstanding facilities, collaborating with leading researchers on projects that push the limits of science and engineering.

The closing date for applications is 12 noon on 9th January 2026. Please upload a CV and supporting statement as part of your online application.
