• Monitor system and pipeline performance and implement improvements to ensure reliability and availability
• Ensure security, compliance, and configuration baselines are implemented and maintained across environments
• Work with identity and credential management tools (e.g., credential managers, service accounts) to support secure automation and access control

• Must have active, in-scope U.S. Government Secret security clearance at the time of application (required to start)
• Ability and willingness to travel up to 10% to support business needs
• Experience with containerization and container runtime technologies (Docker, Podman, or similar)
• Experience with automated testing and software development pipelines/factories (e.g., unit, integration, or acceptance tests in CI/CD)
• Experience deploying applications in containerized environments
• Experience with CI/CD and related tools such as the Atlassian tool suite, Jira, GitHub, GitLab, SonarQube, Checkmarx, Coverity, or Jenkins
• Hands-on experience with Unix/Linux operating systems

Preferred Qualifications

• Strong experience with Linux administration, shell scripting, and operations in production-like environments
• Experience implementing and maintaining automated software testing and analysis within CI/CD pipelines
• Familiarity with hypervisors, virtualized medium- and high-trust environments (e.g., experience working with hypervisors on medium trust environments)
• Experience working with credential and identity management solutions (e.g., credential managers, service accounts, Keycloak or similar technologies) to securely manage non-interactive access
• Exposure to Kubernetes or infrastructure-as-code tools (e.g., Terraform, Ansible) is a plus
