• Ensure patching and major environment changes are tested, approved, communicated and fully evidenced.
• Build and enhance Infrastructure as Code using Terraform and/or CloudFormation.
• Standardise provisioning through reusable modules and reduce configuration drift and operational toil.
• Integrate smoke tests, health checks and post‑deployment validation into CI/CD pipelines.
• Improve monitoring, alerting, dashboards, logging and operational readiness using actionable, SRE‑aligned practices.
• Identify and remediate security, compliance, configuration and platform risks.
• Lead root‑cause analysis and implement preventative automation to improve resilience and recovery readiness.
• Manage, mentor and guide DevOps and environment engineering teams.
• Partner with Engineering, Product, Security, Infrastructure and Operations teams on releases, changes and risk reduction.

• Practical experience with Docker, Kubernetes and Amazon EKS.
• Experience with monitoring, logging and alerting tools such as CloudWatch, Prometheus, Grafana, Geneos, ELK or OpenSearch.
