• Strong Linux engineering expertise, particularly in Ubuntu 22/24 and RHEL, including SOE development and management.

• Ability to independently design infrastructure solutions, solve complex problems, and drive continuous improvement.
• Experience in secure, regulated, or mission-critical environments with a focus on stability, compliance, and operational excellence.
• Strong stakeholder engagement and collaboration skills across infrastructure, security, and application teams.
• Strong experience with automation and Infrastructure as Code (IaC) tools, including Ansible (Must Have), Terraform, Bash, Python, and GitLab CI/CD.
• Government or Federal project experience is a plus
