Job summary

Energy Jobline ZR is seeking a Senior Infrastructure/Platform Engineer to join our defense-technology team in a hybrid role based near Suitland, MD. You will partner with a small core infra group, bringing IaC into classified air-gapped environments and deploying self-hosted tools for secure development.

The role emphasizes hands-on work with Kubernetes, Docker, Pulumi or Terraform, AWS, and SSO platforms, plus CI/CD and observability.

Qualifications

• Active TS/SCI clearance required.
• Hands-on experience self-hosting applications with on-prem or bare-metal infrastructure.
• Deep Kubernetes and Docker experience.
• Experience with IaC using Pulumi or Terraform.
• Strong AWS experience, building environments from the ground up.
• Experience with management and SSO (Keycloak, Authentik).
• Experience with package/artifact management (Artifactory, Nexus).
• CI/CD experience, ideally GitHub Actions.
• Strong Linux and networking fundamentals.
• Ability to code in TypeScript and/or Go.

Responsibilities

• Bring existing infrastructure-as-code into classified and air-gapped environments, deploy it, troubleshoot it and get it working.
• Write new code when an environment behaves differently than expected; about 60% adapting existing code and 40% writing new code.
• Commit your changes back to the main codebase as a full contributor, not just someone who reports what broke.
• Self-host and maintain tools a secure developer environment needs, such as Git hosting, artifact repositories, /SSO and package management.
• Deploy and run services on Kubernetes without relying on managed services.
• Help with CI/CD, DevSecOps pipelines, secrets and configuration management, and observability.
• Work across codebases outside your own when needed; the team is small, so there are no narrow lanes.
