• Design, deploy, and maintain scalable cloud infrastructure on AWS, ensuring high availability, performance, and security across all environments. • Own and evolve Kubernetes cluster management — including bare-metal deployments — and ensure reliable containerised workloads using Docker and Helm. • Build and maintain CI/CD pipelines using GitLab CI, incorporating GitOps principles with FluxCD or ArgoCD to streamline and automate delivery workflows. • Define and manage Infrastructure as Code using Terraform, ensuring all infrastructure changes are version-controlled, repeatable, and reviewed. • Lead monitoring and observability initiatives: implement and maintain dashboards, alerting, and log pipelines using VictoriaMetrics/Prometheus, Grafana, and the ELK stack. • Operate and optimize Apache Kafka ecosystems, including Strimzi, Kafka Connect, and MirrorMaker, to support real-time data pipelines. • Drive incident response, root cause analysis, and post-mortem culture to continuously improve system reliability. • Collaborate closely with Engineering, Security, and Product teams to embed DevOps best practices across the organisation. • Mentor and guide junior engineers, raising the overall engineering bar for infrastructure reliability and automation.
