Experimental Physicist

An innovative technology company based in the Greater Cambridge area is seeking a talented and motivated Experimental Physicist to join a growing research and development team focused on infrared detection and characterisation technologies.

You will design, build, and operate experimental systems for infrared detection, working across the full development pipeline — from sensor selection and optical design through to signal processing and data analysis. The role offers the opportunity to contribute to cutting-edge research and help shape the direction of future development programmes.

You will collaborate closely with a multidisciplinary team of scientists and engineers to develop and refine advanced detection techniques for real-world applications.

• Degree in Physics, Applied Physics, or a closely related discipline
• (PhD preferred, but not essential depending on experience)
• Hands-on experience with infrared sensors, detectors, or imaging systems
• Strong experimental and laboratory skills, including building and troubleshooting optical and electronic systems
• Familiarity with signal processing and data analysis, ideally within a detection or imaging environment
• Practical, methodical problem-solving approach with strong attention to detail
• Good communication skills and ability to work effectively within a collaborative team

• Radiometry and photometry
• Thermal imaging or LWIR/MWIR/SWIR systems
• Optical modelling and simulation
• Experience within defence, security, industrial sensing, or related sectors

• A technically stimulating and research-focused environment
• Competitive salary and benefits package
• Opportunity to work on challenging projects with meaningful real-world impact
• Career development within a high-growth technology organisation
