£600 to £650 Inside IR35
6 to 12 Month Contract
I am working on behalf of a National Security client based out of Cheltenham who are looking for a Senior C++ Engineer to join them on a Contract 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 Python 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.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
