Job Description

Security Architect – Consultant

UK Wide | Hybrid | Permanent | £55,000–£65,000 | Security Clearance

I’m working with a leading National Security and Defence organisation that is looking for a Security Architect to join at Consultant level.

This is an opportunity to work across complex technology environments, helping organisations build security into their architecture rather than treating it as an afterthought.

The Role

You’ll help shape secure technology solutions from the early design stages through to implementation. You’ll assess existing environments, identify security considerations and work with engineering and architecture teams to make sure solutions are designed with appropriate security controls and principles in place.

The role will involve working closely with clients and technical stakeholders, so you’ll need to be comfortable explaining security decisions, challenging designs where required and contributing to wider architecture discussions.

What’s on offer?

  • £55,000–£65,000
  • UK-wide opportunities with hybrid working
  • Consultant-level career opportunity
  • Exposure to complex National Security and Defence programmes
  • Client-facing consulting environment
  • Opportunity to work across infrastructure, applications and wider technology environments
  • Technical development and progression opportunities

What We’re Looking For

  • Experience working in Security Architecture or a closely related technical security role
  • Strong understanding of secure system and technology design
  • Experience assessing architecture and identifying security risks or weaknesses
  • Ability to develop and communicate security architecture principles and patterns
  • Experience working across infrastructure, applications or complex integrated environments
  • Comfortable producing and presenting architecture documentation and design recommendations
  • Strong communication skills with the ability to work with both technical teams and senior stakeholders
  • Consultancy or client-facing experience would be beneficial

Relevant certifications such as CISSP, CISM, SABSA, TOGAF or equivalent are advantageous but not essential where strong practical experience is demonstrated.

Security clearance is required, with higher levels of national security vetting applicable depending on the programme.
