• 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.

• Solid Linux administration skills with deep understanding of system internals.
• Deep expertise in Kubernetes, including bare-metal cluster deployment and day-2 operations. Proficiency with Docker and Helm.
• Hands-on experience with Terraform as a primary Infrastructure as Code tool — writing, reviewing, and maintaining production-grade modules.
• Proven experience with GitLab CI for building and maintaining CI/CD pipelines; familiarity with GitOps practices using FluxCD or ArgoCD.
• Strong background in monitoring and observability: VictoriaMetrics or Prometheus, Grafana, and the ELK stack; solid understanding of log collection and processing with Fluentbit, Fluentd, and Logstash.
• Experience operating and managing Apache Kafka ecosystems, including Strimzi, Kafka Connect, and MirrorMaker.
• Experience with Ansible for configuration management; experience with AWX is a plus.
