Develop embedded software solutions for cutting-edge UK defence technology

to £80,000 DoE + Benefits

This company is growing strongly with projects in various areas of national defence and are seeking a skilled Embedded Software Engineer to join the team. These projects are all specifically related to UK defence and so interested candidates will need to be British Citizens to be considered for this role. Whilst the exact nature of these projects is kept secret, they utilise advanced technologies and often require the development of brand-new techniques to solve very challenging problems.

Whilst growing they are still a small team with a start-up atmosphere where roles aren’t rigidly defined and hierarchy is minimal. New ideas and project directions are welcomed from anyone, and everyone is empowered to represent the business at customer meetings and conferences. You should expect to put your skills to use on a wide array of different projects with varying requirements. Some will be early-stage feasibility studies which may not include any programming while others will run through to the production of prototypes or demonstrator units.

Requirements:

* Demonstrable commercial-grade experience in embedded software development with a proven track record of designing and implementing solutions to real-world problems.

* Strong proficiency with Linux and programming in C, plus at least one other relevant language such as C#, C++ or MATLAB.

* Knowledge in areas such as bare metal and RTOS software development, embedded software debugging methods, high-level software architecture, electronics development, or scripting for test would be highly advantageous.

* Relevant degree demonstrating strong academic foundations including top A Level grades or equivalent.

* British Citizen eligible for UK security clearance.

Remuneration package is strong with good base salary and excellent benefits. For security reasons this is an in-office only role, no forms of hybrid or remote working are possible.
