We are seeking an experienced Principal Enterprise Security Architect to lead the secure design and development of solutions across Legal & General. This role is critical in shaping and maintaining a robust enterprise security architecture by leveraging the collective expertise of the L&G security architecture community.

The successful candidate will be responsible for defining and embedding enterprise-level security processes and artefacts, ensuring that all solutions align with our strategic security objectives and industry best practices.

What you’ll be doing:

• Bringing together the security architecture community across the group by chairing the Security Architecture Community Forum and interfacing with other governance forums to represent collective insights
• Developing tailored artefacts and methodologies for Legal & General, adapting frameworks such as NATO Architecture Framework, Zachman, and SABSA to suit organisational needs
• Maintaining an Enterprise Security Reference Architecture that illustrates how our architecture addresses cyber risks, including documenting accepted risks and associated design patterns
• Collaborating with the Security Policy and Standards team to define and maintain architecture requirements that embed security into solutions and services, ensuring consistency, quality, and strategic alignment
• Leading the transition towards pattern-based design and working with workflow product teams to establish processes for workflow-enabled assurance, identifying what can and cannot be assured through this method
• Producing development roadmaps for central security capabilities in partnership with technology and security teams, shaping priorities to meet future needs and participating in relevant committees
• Ensuring that business and system changes follow best practices and comply with the IT Change Management Standard and approved methodologies

Who we’re looking for:

• Holding a certification in Information Security or IT (e.g. CISSP, CISM, CCP) is preferred but not essential
• Demonstrating applied knowledge of security architecture methodologies such as NATO Architecture Framework, Zachman, or SABSA
• Applying threat modelling techniques to assess and mitigate risks effectively
• Understanding pattern-based design and workflow-enabled assurance; experience with ServiceNow implementation is advantageous
• Possessing strong expertise in enterprise architecture, roadmap design, and defining system requirements
• Bringing practical experience in designing and delivering enterprise solutions from concept to production
• Communicating complex security and architecture concerns credibly with senior IT and business stakeholders
• Influencing strategic direction through thought leadership, with experience in Critical National Infrastructure or Government environments considered beneficial

• The opportunity to participate in our annual, performance -related bonus plan and valuable share schemes
