Job description

Turn cutting-edge physics into defence technology

This high-growth startup in the defence and security sector is seeking an experimental physicist to work on infrared detection systems. You will build and operate their experimental systems working on all aspects of the design from sensor selection and optical design through to signal processing and data analysis. Your work will directly translate to the technologies and products of the company, and your insights will shape their future research direction.

Requirements

• Strong hands‑on skills building and troubleshooting optical and electronic systems using infrared sensors or detectors. Specific experience with thermal imaging or Long-wave / Medium-Wave / Short-Wave IR would be beneficial but is not required.
• Good knowledge of signal processing and data analysis methods in the context of imaging processing and object detection.
• PhD in Physics (or equivalent commercial experience) supported by a top undergraduate degree in Physics (Oxford, Cambridge, Imperial or equivalent).
• UK national or previous UK security clearance. This is a defence company, and this role requires applicants to be eligible for UK security clearance.

This is a great opportunity to further your career working on technically challenging problems with real-world impact. You'll be working alongside other scientists and engineers developing cutting‑edge technologies in a stimulating research environment.
