We are seeking a Junior DevSecOps / CI/CD Engineer to support the development, automation, and maintenance of secure software delivery pipelines for a mission-critical enterprise platform supporting an Intelligence Community customer. The platform provides developers and mission teams with a standardized environment across multiple classified enclaves, leveraging a zero trust, hub-and-spoke architecture.

In this role, you will help maintain and improve the automated processes that move software from development through testing and deployment. You will work alongside experienced DevSecOps engineers, platform engineers, cybersecurity professionals, and integration and test teams to support reliable software delivery, integrate security into development workflows, and maintain the pipeline documentation and evidence needed to support continuous authorization.

This is an opportunity to apply your technical skills in a collaborative environment while developing your expertise in secure software delivery, containerized platforms, and DevSecOps practices supporting national security missions.

Pipeline Development and Maintenance

• Maintain, troubleshoot, and enhance existing CI/CD pipelines using tools such as GitLab CI, Jenkins, GitHub Actions, Argo CD, or similar technologies.

• Support automated software builds, packaging, artifact management, testing, and deployments to containerized environments.

• Use Git for source control, branching strategies, version management, and collaboration across development teams.

• Maintain and extend reusable pipeline templates and automation scripts under the guidance of senior engineers.

• Assist with pipeline configuration and deployment automation using tools such as Terraform, Ansible, Helm, or similar technologies.

Security Integration and Compliance

• Configure and maintain automated security scanning within CI/CD pipelines, including static and dynamic application security testing, software composition analysis, container image scanning, and secrets detection.

• Assist with maintaining hardened container base images and approved artifact repositories.

• Generate, collect, and maintain software bills of materials (SBOMs), scan results, and pipeline evidence supporting Risk Management Framework (RMF) authorization and continuous Authorization to Operate (cATO).

• Follow established security procedures for artifact promotion and deployment across environments, including classified environments where applicable.

• Support cybersecurity and compliance teams in documenting pipeline controls and resolving identified findings.

Operations and Continuous Improvement
