Overview:

We are seeking an expert Enterprise Security Architect with extensive experience in SABSA methodology to join a high-profile public sector project. This is a critical role requiring hands-on experience applying the SABSA framework for top-down security design, and a solid track record of working within a government context. In addition, you must hold valid SC clearance until at least 2028, and it must be continuous - lapsed SC clearance will not be accepted.

• Apply the SABSA methodology to design security frameworks that align business objectives with top-down security governance, ensuring enterprise-wide security integration.
• Expertly implement security standards and frameworks such as NIST, HMG, and SABSA, delivering compliance-driven and scalable security solutions.
• Collaborate with senior stakeholders to define security policies, controls, and risk management strategies, ensuring that security designs align with long-term strategic goals and business objectives.
• Provide technical leadership in the integration of security solutions across diverse IT ecosystems, including multi-cloud environments and critical infrastructure.
• Conduct comprehensive security assessments, identifying vulnerabilities and risks, and develop proactive security strategies that mitigate these challenges.
• Stay ahead of emerging security threats, vulnerabilities, and industry best practices, continuously enhancing the security posture of the organization.
• Serve as a trusted security advisor to stakeholders at all levels, providing expert insights that drive continuous security improvement and operational resilience.

Key Requirements:

• Active SC clearance until at least 2028 (valid, non-lapsed). This is an absolute requirement for this role.
• Hands-on experience with SABSA methodology, specifically in designing and implementing top-down enterprise security architectures - this is non-negotiable.
• Proven expertise in critical security domains, including Identity and Access Management (IAM), cloud security, and vulnerability management.
• Strong experience with NIST, HMG, and other recognized security frameworks, demonstrating the ability to implement secure, compliance-aligned solutions.
• Deep understanding of risk management principles, IT security best practices, and compliance protocols specific to the public sector environment.
• Excellent communication skills, with the ability to influence and engage with both senior leadership and technical teams.
• Strong ability to work both independently and as part of a collaborative team, solving complex security challenges and delivering under tight timelines.
• Experience on government projects within the last 12 months is essential.
