Principal Systems Engineer – Networks (Contract)
Basildon | Hybrid (3-5 days on-site) | Defence Programme
I'm currently supporting a major UK defence organisation as they expand their secure networking capability and are looking for an experienced Principal Systems Engineer with a strong networking background.
This role focuses on the design, implementation, and support of secure enterprise network environments, working across network architecture, lab infrastructure, and integration activities.
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.
