• Experience designing, deploying, and managing solutions on AWS
• Deep knowledge of Linux or Windows OS administration in enterprise environments
• Skilled in IPv4 networking, including design, deployment, and troubleshooting
• Proficiency in Infrastructure as Code (IaC) using tools such as AWS CDK, CloudFormation, or Terraform
• Experience with Docker/Kubernetes for virtualised or containerised systems
• Familiarity with high-security or complex operational environments

Desirable Skills

• Experience implementing CI/CD pipelines in a DevOps context
• Familiarity with Git-based workflows and agile release practices
• Understanding of secure network architecture and configuration of routers/firewalls
• Use of configuration management tools like Ansible or Puppet
• Comfortable working with agile tools (e.g. Jira, Confluence) and frameworks (e.g. Scrum, SAFe)
• Knowledge of ITIL service management principles
