About the Organisation

My client is a major UK organisation whose work has a direct and tangible impact on everyday life across the country.

Their IT function is the trusted digital partner across a large and complex estate, with around 1,000 technology professionals. The organisation is on a long-term digital and cyber transformation journey and is investing in senior architectural leadership to significantly mature its enterprise security capability.

The Opportunity

My client is seeking a Principal Enterprise Cyber Architect to lead and shape enterprise-wide cyber security strategy across a complex, hybrid technology environment.

This is a strategic, enterprise-level role, rather than a hands-on delivery position. You will define architectural direction, principles, and guardrails that enable teams to build secure, resilient services at scale.

Zero Trust and Secure by Design are already in place; your role will be to mature, embed, and scale these approaches, improving consistency, assurance, and adoption across both cloud and on-premise environments.

Candidates must be comfortable working across AWS and/or Azure alongside significant on-premise estates, selecting the right solution for the organisation rather than advocating a single cloud platform.

Key Responsibilities

• Own and evolve enterprise cyber security architecture strategy, standards, and patterns
• Act as a technical design authority, influencing major decisions, investment cases, and long-term roadmaps
• Define pragmatic security guardrails that support delivery at pace
• Lead threat modelling, resilience, and risk-based design at enterprise scale
• Mature Zero Trust, Secure by Design, and cloud security capabilities
• Partner with senior technology and business stakeholders to align security with organisational priorities
• Anticipate emerging threats and regulatory change, translating them into actionable architectural direction
• Provide architectural leadership across internal teams and suppliers

This role has no direct line management but carries significant enterprise-wide influence.

About You

Essential:

• Strong enterprise architecture background with deep cyber security architecture expertise
• Experience defining enterprise-level security strategy and design
• Strong understanding of cyber security principles, patterns, and threat-based design
• Experience across hybrid estates (cloud and on-premise)
• Confident acting as a senior design authority and advisor
• Experience setting standards and guardrails at scale

Desirable:

• Experience maturing security capability in evolving environments
• Familiarity with industry frameworks (used pragmatically)
• Background in large, complex, or regulated organisations

Security & Eligibility

• SC clearance required (sponsored on offer)
• UK residency for the last 5 years
• No visa sponsorship available

Why Join?

• Shape cyber security at true enterprise scale
• Focus on long-term strategy rather than firefighting
• Flexible working and strong work-life balance
• Market-leading 29% pension contribution
• Opportunity to leave a lasting architectural legacy
