iO Associates are currently looking for an SC Cleared Offensive Security Engineer for an initial 6‑month contract role (OUTSIDE IR35) based in London. Day rates will be based on level of experience.

You must hold active SC or DV Clearance for this position and the client would need someone onsite in London 2‑3 days a week.

• Deep SME‑level expertise in offensive security to design, develop, and shape technical cyber solutions.
• Involves working closely on complex projects and contributing directly to product creation and delivery.
• Role supports Defence and Secure Government clients, so active security clearance is required.

We would like someone to start ASAP but can accommodate longer notice periods if needed for the right candidate.
