Managing Security Architect

Do you want to help shape the future of our SOC?

This is your chance to take ownership of the end‑to‑end SOC architecture, guiding how our platforms, detections and controls evolve to meet client, regulatory and business needs. You’ll influence how our services grow, introduce new technologies and strengthen a security‑by‑design culture.

You’ll join a team operating at the heart of National Security, working in an environment where you’ll be trusted to innovate, contribute ideas and help us stay ahead of emerging threats. We’re a supportive group who share knowledge, mentor colleagues and take pride in delivering high‑quality services to our customers.

This is a hybrid role, and you’ll spend two days a week in either Hemel Hempstead or Farnborough – giving you the balance of collaboration time with the team and the flexibility to work from home for the rest of the week.

You do need to be eligible for SC and DV Clearance.

What you'll be doing:

• Owning the SOC architecture to ensure designs, integrations and operating models meet regulatory and assurance requirements.
• Documenting high and low‑level security control designs and defining testing needs.
• Setting and governing standards for detection content, including rules, use cases and correlation logic.
• Acting as the technical authority for client security designs and technology roadmaps.
• Leading SOC maturity work to support CREST accreditation.
• Identifying and introducing technologies that enhance analyst effectiveness, including automation and AI.

What you’ll bring:

• Experience designing or owning security architectures within SOC, MSSP or complex security environments.
• Strong understanding of detection and SOC operations.
• Ability to oversee security platforms and integrations holistically.
• Knowledge of governance, compliance and accreditation requirements such as CREST.
• Experience assuring technical architectures using secure design principles.

If you’re interested in this role but not sure if your skills and experience are exactly what we’re looking for, please do apply, we’d love to hear from you!
