DevSecOps Engineer - Intelligent Platforms & Agents

Leidos is advancing mission-critical platforms that simulate and interact with complex technical and business environments. The DevSecOps Engineer will be responsible for building and automating the delivery infrastructure, maintaining CI/CD pipelines, and ensuring security compliance while collaborating closely with software engineers and systems engineers.

Responsibilities:

• Design, implement, and maintain automated CI/CD pipelines that carry code from development through security scanning, compliance validation, and deployment into Navy and DoD environments
• Build and maintain hardened Kubernetes environments aligned to DISA STIG requirements across cloud and restricted network deployment contexts
• Automate security artifact generation including SBOM production, CVE scanning, and continuous compliance validation
• Drive adoption of Infrastructure as Code, GitOps practices, and controls-as-code across the team
• Leverage AI tooling to accelerate pipeline development, vulnerability triage, compliance remediation, and operational documentation
• Partner closely with software engineers, systems engineers, and ISSEs to embed security and compliance requirements from the start of development
• Maintain and evolve deployment infrastructure across multiple secure environments, including cloud and air-gapped or intermittently connected contexts
• Support ATO processes through automated evidence generation, documentation as code, and direct collaboration with the security team
• Establish and promote standards for pipeline design, container security, secrets management, and deployment consistency
• Contribute to feature development when team capacity requires, applying security-first development practices to application code
• Maintain operational documentation including runbooks, deployment guides, and architecture diagrams as version-controlled artifacts

Requirements:

• Must have and maintain a Secret security clearance
• BS degree and 4+ years of professional DevSecOps or DevOps engineering experience, 8+ years of total relevant experience
• Hands-on experience designing and maintaining CI/CD pipelines using GitLab CI; experience with additional pipeline tools a plus
• Experience with Kubernetes administration and hardening in DoD or compliance-driven environments - RKE2 or K3S experience strongly preferred
• Experience implementing DISA STIG compliance in containerized and Linux environments (RHEL or Rocky Linux)
• Proficiency with Infrastructure as Code tooling, particularly Terraform
• Experience with Helm chart authoring and Kubernetes deployment management
• Experience with automated security scanning, SBOM generation, and CVE triage and remediation
• Scripting proficiency in Python or Bash for pipeline and operational automation
• Demonstrated use of AI tooling to accelerate engineering workflows
• Background contributing to application feature development alongside infrastructure work
• Ability to operate independently and manage workload across competing priorities in a small, fast-moving team
• Experience operating in air-gapped or disconnected network environments
• Experience supporting ATO through automation, documentation, and technical leadership
• Active Security+ certification or equivalent IAT Level II certification
• Experience with secrets management tooling such as Vault, Sealed Secrets, or SOPS
• Familiarity with observability and monitoring tools such as Prometheus or Grafana
• Certified Kubernetes Administrator (CKA) or willingness to obtain upon onboarding
• Experience applying 'as code' approaches beyond infrastructure (e.g., configuration-as-code, policy-as-code, workflows-as-code, documentation-as-code)
