Sytems Administrator/Tester

About the role

Responsible for the administration, operation, troubleshooting, and security of IT infrastructure supporting containerized applications. This includes container runtimes, orchestration platforms, cluster networking, persistent storage, and related security controls. Uses systems analysis techniques to diagnose and resolve issues affecting containerized workloads, nodes, storage, and connectivity, ensuring availability, performance, and integrity of the environment. Applies security patches, OS and Kubernetes upgrades, and container image updates. Supports new container‑platform infrastructure projects and maintains accurate configuration documentation for assigned systems.

Time Type: Full time | Minimum Clearance Required: TS/SCI | Travel Required: None

Responsibilities

• Identify problems in the container environment, perform root‑cause diagnosis (pod/node failures, resource constraints, CNI/overlay networking issues, persistent volume problems, control‑plane issues), and develop corrective action plans.
• Corrective maintenance: isolate and restore failed containerized services, nodes, or cluster components.
• Perfective maintenance: optimize cluster performance, resource allocation, autoscaling, and observability.
• Adaptive maintenance: update configurations, perform version upgrades, adapt to new security or infrastructure requirements, and support platform changes while preserving workload functionality.
• Manage container lifecycle operations (image management, deployments, rollouts, scaling) and the underlying container‑runtime infrastructure.
• Create and maintain as‑is documentation, including high‑level architecture diagrams of the containerized environment (clusters, namespaces, workloads, services, ingress, storage classes, networking, integration points) and associated system requirements.
• Support maintenance of active security authorizations (A&A) and Body of Evidence artifacts (POAMs, control implementations, test plans).
• Implement applicable STIGs, CIS Kubernetes Benchmarks, vendor hardening guides, and ensure timely patching of nodes, container images, and related components.
• Integrate with enterprise security services and use required tools (XACTA 360, Service+, CPT, SWAP, etc.).
• Support build, test, and deployment of container images, Helm charts, manifests, and infrastructure configurations via enterprise, government‑managed CI/CD pipelines (where applicable).
• Focus on platform operations, image/registry management, and orchestration—not application code development.

Qualifications

• Bachelor’s degree in Computer Science, Information Systems, Engineering, or a related technical/scientific discipline.
• Minimum of six (6) years of system administration experience.
• Experience with container technologies (Docker, Kubernetes) and preferably AWS (EKS or equivalent) or comparable cloud/on‑premises container platforms.
• CompTIA Security+ certification or ability to obtain within 90 days.
• Active/current TS/SCI clearance with the ability to obtain and maintain a Polygraph.
• Desired: Experience with Helm or similar packaging tools.
• Desired: Container security knowledge (image scanning, network policies, runtime protection, CIS benchmarks).
• Desired: GitOps experience and CI/CD pipelines for container deployments.
• Desired: Prior experience in classified DoD/IC environments supporting A&A processes.

Benefits

• Culture of integrity, innovation, and a high‑performing team dedicated to mission success.
• Environment of trust with a flexible time‑off benefit.
• Robust learning resources to support personal and professional growth.
• Opportunities for continuous career advancement.
• Competitive compensation.
• Comprehensive benefits package including healthcare, wellness, financial, retirement, family support, continuing education, and additional time‑off benefits.
