Firmware Engineer - Electronics Hardware Integration - Defence - Cambridge We have an important Firmware Engineer role for a growing Defence Sector organisation, aimed at contributing to the development of new technologies that will enhance the defence of the UK and other allied nations, with a focus on defensive technologies rather than offensive. Ideally, we are looking for someone with an electronics engineering background who can leverage their Firmware Engineering experience along with knowledge of electronics hardware integration. It's preferable if you have a proven track record of successfully completing complex projects resulting in launched devices. Some of the project you will be involved in will be focus on the advancing new technologies, pushing boundaries, and doing things that no one has done before. This means you won't get bored in this role and will continue to develop your careers and skills. While prior experience in the Defence sector is ideal, we are open to consider candidates from other complex fields. You will need to hold a degree in a software or electronics field that led you into a Firmware Engineer career.

In addition to career development and interesting projects, you will also receive an excellent starting salary (dependant on experience level), bonuses, a pension, free lunches, healthcare, on site gym access and other excellent benefits typically associated with larger organisations.
