• Support the availability, capacity and reliability of on premises Kubernetes infrastructure and systems.
• Provide Level 2 and Level 3 operational support, leading incident response activities, contributing to root cause analysis, and implementing preventative improvements that enhance system resilience.
• Develop and maintain monitoring, alerting and logging capabilities, using meaningful service metrics, SLOs and SLIs to drive performance insights and continuous improvement.
• Enhance automation, infrastructure-as-code and CI/CD practices across the environment, partnering with development and platform teams to enable consistent, secure and reliable deployments.

About You

You are someone who enjoys solving complex operational challenges and takes a thoughtful, collaborative approach to improving system reliability. You bring a combination of infrastructure expertise, automation capability and a continuous improvement mindset, enabling you to contribute effectively within high-availability environments supporting critical business outcomes.

Essential

• Experience in Linux/UNIX administration, including troubleshooting, performance analysis and operational support within enterprise environments.
• Capability in developing automation using Python, Go, Bash or similar scripting languages to improve operational efficiency and reduce manual effort.
• Experience implementing and maintaining Infrastructure as Code and configuration management solutions using tools such as Ansible, Terraform, Puppet or Chef.
• Knowledge of monitoring, logging and observability practices, with the ability to use service metrics and operational data to improve reliability and performance.
• Experience supporting virtualised and/or cloud-based environments, including technologies such as VMware, AWS, Azure or GCP.
• Experience working with CI/CD pipelines and deployment automation tools such as Jenkins, GitLab CI or similar platforms.
• Ability to investigate complex incidents, contribute to root cause analysis and implement sustainable corrective actions.

Advantageous

• Experience supporting systems within Defence, National Security or other highly regulated environments.
• Familiarity with fault-tolerant, large-scale production systems and high-availability infrastructure architectures.
• Knowledge of secure systems administration practices, compliance requirements and operational governance frameworks.
• Exposure to DevOps, platform engineering or site reliability practices within mission-critical environments.
