Overview
Security Architect | Public Sector & Defence Consulting
Clearance needed (SC or DV considered)
Ncounter is supporting a specialist UK consultancy at the forefront of national security, defence, and public sector transformation. They are looking to add an experienced Security Architect who enjoys operating as a trusted advisor, shaping secure solutions for complex, high-impact programmes rather than sitting in a purely delivery or compliance role.
This position suits someone who has moved beyond single-project architecture and is comfortable engaging senior stakeholders, influencing design decisions, and embedding security across delivery teams. You will work across a varied portfolio of assignments, advising on risk, architecture, and secure delivery for nationally critical systems.
Responsibilities
* Engaging directly with client teams to understand threat landscape, risk appetite, and delivery constraints
* Defining and documenting proportionate security architectures aligned to business outcomes
* Leading threat modelling and security design reviews across digital programmes
* Selecting and allocating security controls across cloud, application, identity, and network components
* Providing architectural assurance and constructive challenge to delivery teams
* Supporting the development of security policy, standards, and reusable patterns
* Advising on secure procurement and evaluating technical options
Qualifications
* A strong background in security architecture within public sector or defence environments
* Experience operating across Secure by Design, NIST, SABSA, Zero Trust, or similar frameworks
* Hands-on exposure to cloud platforms, modern SDLCs, and CI/CD pipelines
* Confidence working across multiple classifications and complex stakeholder groups
* A consulting mindset, comfortable balancing strategic oversight with practical guidance
Benefits
The consultancy offers long-term career development, varied client exposure, and the opportunity to shape security outcomes that genuinely matter. Hybrid working is standard, with client-site collaboration when required.
