Implement zero downtime deployment strategies (blue/green, rolling, canary) with automated rollback and recovery.

Drive infrastructure improvements, reducing single points of failure and enhancing autoscaling, high availability, and managed service utilisation.

Collaborate with SRE, Security, and Engineering teams to improve observability, monitoring, and alerting using tools such as Prometheus, Grafana, and CloudWatch.

Work closely with Security to embed best practices for IAM, secrets management, WAF, and governance.

Optimise performance and cloud spend through automation and cost visibility tooling.

Participate in on call rotations, incident reviews, and ongoing reliability enhancements.

Requirements

Proven experience designing, automating, and maintaining AWS infrastructure (EKS, RDS, EC2, CloudFront, VPC, IAM, Security Hub).

Hands on experience building IaC pipelines using Terraform and integrating with CI/CD tools (GitHub Actions, GitLab CI, Jenkins, AWS CodePipeline, etc.).

Strong understanding of Kubernetes operations on AWS, including scaling, deployment automation, and monitoring.

Solid background in Linux systems administration, networking, and cloud security.

Familiarity with observability tools such as Prometheus, Grafana, and Loki, and structured alerting practices.

Experience with database migrations, high availability configurations, backups, and disaster recovery.

Strong scripting and automation skills (Terraform, Python, Bash, or similar).

Excellent communication and collaboration abilities, with a drive to improve engineering efficiency through automation and standardisation.
