We are expanding our Security Architecture capability and seeking experienced Principal Security Architects who can shape, assure, and enable delivery of secure, cloud-native services at scale. You will be comfortable working across the full systems lifecycle, from discovery and architecture through delivery and transition to live, serving as a trusted "customer friend". You'll partner with engineering, product, and senior leadership to embed Secure by Design, de-risk complex change, and simplify security for decision-makers. A strong grasp of how contemporary cloud-native services (containers, Kubernetes, microservices/serverless, identity, secrets, and zero trust patterns) are designed and implemented is essential to success in this role. Our consultants lead parallel workstreams spanning security engineering and assurance, maintain day-to-day client engagement, and contribute to presales and bid activity when needed. What you'll do * Conduct and iterate threat models for new features and integrations; translate findings into actionable design and control decisions. * Advise on secure architecture for modern platforms (segmentation, identity/access, encryption, data protection, secrets, and resilience). * Recommend and review controls for containerised and serverless workloads; guide teams on secure coding and code review practices. * Support incident response planning and playbook development; foster a culture of continuous assurance. Your experience will include: * Leading the development of security architecture and design for complex IT requirements, ensuring smooth transition from design to live service. Managing trade-offs based on stakeholder needs and constraints while championing and driving transformation through a clear vision and architecture to lead the delivery journey. * Enabling delivery through the definition of methodologies, approach, team structure, and supporting technologies that enable successful transformation across an engineering lifecycle. * Shaping policies, principles and standards, aligning IT transformation to these in an organisational/enterprise context, in order to deliver efficiently. * Ensuring full lifecycle traceability of stakeholder requirements, supporting project planning with accurate assumptions, and simplifying complexity for senior stakeholders. * Familiarity with TOGAF and Archimate or similar. Employment is subject to satisfactory BPSS and SC security clearance, which requires 5 years' continuous UK address history at the point of application.
