Principal Security Architect (SPaR)

Reference: by93btorgq4qmdy4nv16

We are seeking an experienced Principal Security Architect to provide strategic leadership across security architecture, risk management and secure technology delivery. In this senior role, you will define and maintain security architecture principles, standards and patterns, ensuring that business strategies, technology roadmaps and transformation programmes are aligned with robust security outcomes. You will work closely with senior stakeholders, engineering and delivery teams to embed security by design across applications, infrastructure, cloud services, data and emerging technologies.

Your responsibilities will include assessing current and future security capabilities, identifying architectural risks and recommending proportionate mitigations. You will lead the production and review of security architecture documentation, threat models, design decisions and technical assurance reports, while supporting governance forums and investment planning. You will provide expert advice on complex initiatives, challenge proposed designs where necessary and help teams translate security requirements into practical, deliverable solutions. The role will also involve contributing to security strategy, policies and reference architectures, supporting risk acceptance processes and promoting consistent approaches across a diverse technology estate. You will act as a trusted adviser during major incidents, technology change and supplier engagements, helping to ensure that security controls remain effective and appropriate.

Applicants should have substantial experience in security architecture, cyber security or a closely related discipline, together with a strong understanding of enterprise architecture and modern technology environments. You will need practical knowledge of cloud security, identity and access management, network security, application security, data protection, secure development and risk assessment. Experience of recognised security frameworks, architectural methods and regulatory or compliance requirements would be highly beneficial. Professional security or architecture certifications are desirable, although equivalent experience will be considered. Strong communication and influencing skills are essential, as is the ability to explain complex issues clearly to technical and non-technical audiences. We are looking for someone who can operate strategically while remaining sufficiently hands-on to guide delivery teams and achieve measurable improvements in security maturity.
