The projects we work on are highly diverse and you will combine your existing skills and knowledge with an appetite to rapidly identify and assimilate whatever new information is necessary to solve the problem at hand. Examples of recent work undertaken for our clients include:  

• Development of a novel imaging system based on multi-wavelength holography  
• Design, simulation and manufacture of custom ultrasonic measurement system  
• Development of a miniaturised magnetic positioning system for a high-volume consumer product  
• Teardown and reverse engineering of complex high-power laser instrument for industrial application  
• Technical analysis of superconducting power distribution system  

You will work alongside a project team who is delivering one of our ongoing projects for an external customer where you will and solve a variety of challenges which support the development of a novel system. This is likely to include both practical laboratory experimentation as well as and simulation and physical modelling. The focus of this work will be optical physics and/or integrated photonics. 

You will have access to our extensive in-house laboratory and prototyping facilities, and work with engineers and scientists from a range of disciplines, including AI/algorithms, mechanical engineering and electronic engineering. You will be supported and guided by members of our Applied Science team. 

• Strong academic credentials, with a solid foundation in physics 
• Interest in working in the lab, as well as conducting desk-based analysis  
• A collaborative approach 
• An interest in optical/photonic systems 
• The ability to gain UK security clearance 

Most importantly, you must be willing to take on new challenges, learn on the job, and grow your capabilities. 

Some projects at Cambridge Consultants are subject to security restrictions. This role requires you to obtain a Security Check level security clearance ( https://www.gov.uk/guidance/united-kingdom-security-vetting-applicant ). You must be able to work in the UK without restrictions in accordance with UK National Law and be prepared to successfully undertake an appropriate level of UK National Security Vetting according to UK Government National Security Vetting criteria.

Please ensure your CV includes your A Level (or equivalent) subjects and grades, as well as any relevant university modules.
