DevSecOps Engineer - Kubernetes

ClearanceJobs is actively seeking a DevSecOps Engineer for our client located in Herndon, VA. ClearanceJobs is the largest career network for professionals with federal government security clearances, connecting cleared talent with the opportunities that matter most. We are committed to matching top-tier candidates with clients who depend on mission-focused professionals to support national security, defense, and intelligence community initiatives. Our team works closely with hiring managers to understand their needs and deliver candidates who are not only technically qualified but cleared and ready to contribute from day one.

The ideal candidate must have experience to join the platform engineering team supporting a mission-critical geospatial intelligence system used across the U.S. military and intelligence community. This role is focused on building and operating the infrastructure that keeps a high-availability, enterprise-scale platform running - CI/CD pipelines, containerized workloads, security-embedded delivery, and automated environment management.

You will work embedded within an Agile delivery organization, partnering with software development Scrum teams to ensure reliable, repeatable deployments and a hardened platform that meets the security and performance demands of a national security mission. If you thrive in a pipeline-and-platform role and want long-term stability on a meaningful IC program, this is that opportunity.

Responsibilities will include, but not limited to:

• Design, build, and operate CI/CD pipelines for containerized workloads across development, test, and production environments.
• Administer and maintain Kubernetes clusters - including RBAC, networking, ingress controllers, secrets management, autoscaling, and lifecycle upgrades.
• Package and deploy services using Helm and Kustomize with repeatable, versioned release strategies aligned to GitOps standards.
• Automate environment provisioning using Infrastructure as Code tooling, embedding security controls and compliance checks at every stage of the pipeline.
• Implement and enforce DevSecOps practices including automated security scanning, policy-as-code, and audit-ready pipeline documentation.
• Partner with development Scrum teams during Agile ceremonies to support deployment planning, environment readiness, and release coordination.
• Contribute to platform observability - monitoring, alerting, and incident response - to sustain operational uptime as the program’s primary mandate.
