    Job Description

    Developing clever embedded C and C++ software to support national security applications

    Based in Tewksbury, this established consultancy provides broad technical expertise in disciplines such as algorithm development, signal processing, RF systems design, FPGA development, and software development for data capture and hardware control. Their clients are typically the UK Government or small companies needing specialist knowledge to complete their own projects. The work is varied and cross-disciplinary in nature. Software is typically developed in C or C++ under Linux, with HTML and TypeScript/JavaScript being used for user interfaces.

    As a senior consultant, you will be involved throughout the project lifecycle with a high degree of client contact and autonomy over your work. This role would likely suit an experienced C++ developer from the defence sector seeking interesting work without a big-company corporate culture or drawn out project time frames. This role is a great opportunity to build experience and learn new skills while working as part of a supportive and collaborative team.

    You will need:

    • A 1st or 2.1 in a numerate STEM discipline and strong pre-university grades (A or A at A-levels, or equivalent). A relevant Master's or PhD would be advantageous

    • Excellent communications skills: being confident discussing complex technical concepts with clients and colleagues and proficiency in authoring technical documentation

    • Software engineering skills in C or C++ and Linux. Familiarity with common software engineering tools and best practice are essential. Front end development skills in TypeScript/JavaScript and HTML would be useful.

    • Full right to work in the UK and ability to obtain a higher level UK security clearance. Typically this will require you to have British nationality and to have been resident in the UK for 10 years This role is fully office-based due to the nature of projects, but there is some flexibility on working hours to allow for employees circumstances. A highly competitive salary is on offer to the successful candidate and the benefits package includes a performance-based bonus and an excellent pension scheme.
