5. Microservices Architecture: Oversee microservices development, focusing on Java-based backend services.
6. Technical Leadership: Mentor teams through complex technical challenges and architectural decisions.
7. Security & Compliance: Ensure architectures comply with regulations (GDPR, HIPAA) and security policies.
8. CI/CD & Automation: Promote CI/CD pipelines, infrastructure as code (Terraform, CloudFormation), and automation.
9. Collaboration: Work with DevOps, engineering, product management, and stakeholders to align strategies.
10. Performance & Cost Optimization: Drive performance tuning and cloud cost management.
11. Risk Management: Identify and mitigate technical risks.
12. Documentation & Best Practices: Maintain architectural standards and documentation.

• Cloud security architecture (IAM, network security, encryption)
• Containerisation with Docker and Kubernetes
• Event-driven architectures with Kafka
• Java-based microservices development

• Understanding of TOGAF architectural standards

Applicants must be British citizens, have lived in the UK for the last 5 years, and be able to obtain high-level security clearance.
