• Drive cloud migration programmes end-to-end, including application assessment, readiness analysis, refactoring strategies, and transition planning
• Shape and deliver platform roadmaps, enabling scalable, resilient, and cost-efficient cloud operations
• Champion automation-first engineering, using Infrastructure-as-Code (Terraform, Ansible) and GitLab-based CI/CD pipelines to improve consistency and speed
• Ensure platform reliability, security, and compliance, embedding engineering standards, architectural patterns, and governance controls across all workloads
• Enable hybrid-cloud integration, supporting selective adoption of Azure services where required
• Collaborate across architecture, security, and operations teams to enforce platform guardrails and guidelines
• Lead and develop engineering teams, encouraging a culture of ownership, learning, and continuous improvement
• Coordinate sprint planning, prioritisation, and delivery execution across multiple engineering streams
• Represent Cloud & Platform Engineering in governance, architecture, and programme forums
• Act as the focal point for complex cloud and Kubernetes challenges, making informed technical and operational decisions

Requirements

• Deep expertise in AWS services, including EKS, IAM, networking, compute, observability, and security
• Strong hands-on experience with Kubernetes and container platforms, including cluster operations and workload optimisation
• Proven experience with Infrastructure-as-Code, CI/CD pipelines, and DevOps tooling
• Solid understanding of hybrid cloud architectures, networking, identity, and security controls
• Experience applying SRE principles, observability frameworks, and managing distributed systems at scale
• Demonstrated success leading cloud transformation and migration programmes

Leadership & Collaboration

• Proven ability to lead and inspire engineering teams, delivering complex cloud initiatives
• Strong customer management skills, with the ability to influence technical direction across diverse teams
• Ability to translate complex technical concepts into clear insights for both technical and non-technical audiences
• Comfortable operating in fast-paced, enterprise-scale environments with multiple priorities

Qualifications

• A Degree or equivalent in Computer Science, Engineering, or equivalent practical experience
• AWS certifications (e.g., Solutions Architect, DevOps Engineer) preferred
• Kubernetes certifications (CKA/CKAD) and DevOps/SRE certifications beneficial
• Azure certifications advantageous but not required
