SC Cleared Software Support Engineer

£600-£650 per day - Inside IR35 - 6-month contract - Onsite in Stratford - Willing to go through DV Clearance

iO Associates are looking for an experienced Application & Infrastructure Engineer to join a specialist team supporting highly sensitive, business-critical systems within a national operational environment.

This is a broad technical role covering application support, infrastructure, development and incident management, offering plenty of variety and the opportunity to work across a constantly evolving technology landscape.

What you'll be doing:

  • Build, enhance and support critical bespoke applications, contributing to application design, development and ongoing maintenance.
  • Manage Linux and Windows infrastructure, including databases, virtualised environments and system health monitoring.
  • Investigate and resolve application and infrastructure issues, ensuring system stability, performance and availability.

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.
