I am working on behalf of a National Security client based out of Cheltenham who are looking for THREE Senior C++ Engineers to join them on a Permanent basis.

We're looking for a C++ Engineer who has led end-end projects and enjoys solving complex technical problems in areas like software defined radio. The role would suit someone open to some pythons for tooling, automation, or testing alongside core C++ development. If you are currently working in Security, Defence or Financial Services this would be a big bonus for the client.

The client is really looking to just hire the right Engineers for this one so are happy to wait, so even if you have a 3 Month notice period that's not as issue. Again, this role will be based out of Cheltenham 4-5 Days per week and you must be SC Cleared or SC Clearable to be considered.

If you're interested, please do respond with your updated CV as I will be calling through applicants in order of receipt
