About the Role:

We are looking for a highly skilled Lead Technical Architect with expertise in cloud architectures to design, implement, and oversee cloud infrastructure solutions for mission-critical systems. The role involves using your knowledge of security architecture on cloud platforms to lead in building scalable, secure, and resilient cloud-native systems based on AWS, Kubernetes, Kafka, microservices, Java, and event-driven design.

Key Responsibilities:

1. Cloud Architecture Design: Lead design of cloud-based systems using AWS, microservices, event-driven architectures, and serverless computing to meet business needs.
2. Cloud Security: Develop and implement security architectures, ensuring data protection, compliance, and best practices (AWS IAM, encryption, VPC, monitoring, auditing).
3. Containerisation & Orchestration: Architect and oversee Kubernetes environments for high availability and scalability.
4. Event-Driven Systems: Lead architecture of systems using Kafka for real-time data processing across microservices.
5. Microservices Architecture: Design and oversee microservices-based systems, focusing on Java backend services.
6. Technical Leadership: Provide mentorship and guidance to teams on complex technical challenges.
7. Security & Compliance: Ensure architectures comply with regulations (GDPR, HIPAA) and security policies.
8. CI/CD & Automation: Promote 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 cost management strategies.
11. Risk Management: Identify and mitigate technical risks.
12. Documentation & Standards: Maintain architectural standards, design patterns, and documentation.

The Fit:

Ideal candidate has experience in large-scale cloud systems with AWS, security architecture, containerisation (Docker, Kubernetes), Kafka, Java, CI/CD, IaC (Terraform, CloudFormation), monitoring tools, serverless (Lambda), and holds relevant AWS certifications. Understanding of TOGAF is a plus. Must be a British citizen with at least 5 years UK residence for security clearance.
