• Automate and modernise our platform: build automation with AWS CLI, Boto3, Terraform, Cloud Formation; deploy containerised workloads with Docker & Kubernetes.
• Strengthen cloud security: implement IAM least‑privilege access; use Security Hub, Guard Duty, Macie, WAF and Network Firewall; lead encryption and secrets through KMS & Secrets Manager.
• Enable data movement & platform performance: support secure transfers with AWS Data Sync and AWS Transfer Family (SFTP); lead monitoring and observability with Cloud Watch, Dynatrace and Splunk; drive incident response, root‑cause analysis and service improvement.

• Hands‑on experience with AWS infrastructure, automation and observability tooling.
• Strong understanding of DNS, SSL/TLS, TCP/IP and core networking principles.
• Familiarity with cloud cost optimisation and multi‑cloud environments.

You'll work with modern AWS services, collaborate with dedicated engineering teams and help shape secure and scalable cloud solutions used across the Group. You'll be part of a community driving innovation, learning and best‑practice engineering.

We're committed to building an organisation that reflects modern society and celebrates diversity in all its forms. We want all our people to feel they belong, can be their authentic selves and reach their full potential.
