SRE – Security Infrastructure – C2C – TS/SCI FSP

  • Virginia, Virginia, United States

Site Reliability Engineer Security Infrastructure

Washington, DC | Secret Security Clearance Required

Own, Build, and Secure Mission-Critical Infrastructure

This is not a traditional SRE role:

We are looking for an elite hands-on systems engineer who thrives in high-stakes, complex environments. This role requires deep expertise in Kubernetes, Linux, cloud infrastructure, and automation. Expect to own, build, and secure massive-scale infrastructure, writing the code and deploying the systems that defend against advanced threats.

The Work:

  • Build Kubernetes from the ground up, operating large-scale clusters across cloud and air-gapped environments.
  • Engineer and automate enterprise cloud infrastructure, designing resilient, high-performance security platforms.
  • Write and optimize Linux scripts, Python automation, and infrastructure as code (IaC) to streamline operations.
  • Develop and manage massive security data pipelines, handling terabytes of real-time telemetry.
  • Dig into system internals, troubleshoot performance at the OS level, and optimize distributed security systems.
  • Work independently at a high level, making critical architectural decisions while staying hands-on with implementation.

What You Bring:

  • 5+ years of hardcore systems engineering experience, with expertise in Kubernetes, cloud infrastructure (AWS, GCP, Azure), and automation.
  • Fluency in Linux, Python, and shell scripting. Comfortable writing code that controls, monitors, and secures enterprise infrastructure.
  • Deep networking and security knowledge, understanding system internals, monitoring, and threat response.
  • A self-directed, execution-driven mindset, capable of operating as a high-value independent contributor.
  • Active TS/SCI Fullscope Poly Clearance required.
  • Corp to Corp structure.

Why This Role?

  • Total ownership: design, build, and operate security infrastructure at global scale.
  • Deep technical work: get your hands into system internals, Kubernetes internals, and large-scale cloud environments.
  • Mission-critical impact: defend against nation-state threats in an elite engineering environment.
