Job Level

Tech Stack

About the role

  • Architect the compliance engine.
  • Design and build the policy-as-code infrastructure that sits at the heart of the platform: the enforcement points, evidence pipeline, continuous compliance dashboards, and attestation framework that make "approved to deploy" a machine-verifiable fact, not a permission you wait on.
  • Own the platform ATO strategy. Chart the path from where we are to a platform-level ATO that programs can inherit.
  • Navigate RMF, NIST 800-53, NIST 800-171, NIST 800-160, and DoD IL4/IL5 requirements alongside the realities of working with internal security reviewers and external auditors (3PAOs, DCMA).
  • Be the enterprise security team's most important technical partner. Attend the meetings. Build the trust. Co-author the policies.
  • Build the agentic AI security model.
  • Own security architecture across the developer platform. Threat model the full stack—CI/CD pipelines, developer portal, container runtimes, and workstation environments.
  • Lead the supply chain security effort. SBOM generation, dependency management, container image provenance, vulnerability scanning- you design the enterprise pattern, build the tooling, and make it automatic.
  • Drive ATO process re-architecture.

Requirements

  • Masters degree in Computer Science, Information Security, Software Engineering, or related technical field.
  • 15+ years of experience in security architecture, DevSecOps, platform security, or related disciplines—with significant hands-on work, not just advisory roles.
  • Deep expertise in policy-as-code tooling: Open Policy Agent (OPA), Kyverno, Rego, Sentinel, or equivalent.
  • Strong working knowledge of compliance frameworks: NIST 800-53, NIST 800-171, NIST 800-160, FedRAMP, DoD IL4/IL5/6, RMF, CMMC.
  • Hands-on experience with container and Kubernetes security: admission controllers, image scanning, network policies, runtime security, and hardened base images.
  • Experience with CI/CD pipeline security: SAST/DAST, SCA, container scanning, IaC scanning, secrets management, hardened images/libraries, and how to integrate these into developer workflows without crushing velocity.
  • Familiarity with software supply chain security: supply chain integrity frameworks (SLSA, in-toto), SBOM standards (CycloneDX, SPDX), signed commits, and provenance tooling.
  • Experience designing security for AI-assisted development environments, including agent tooling, MCP server governance, LLM-integrated development pipelines, or equivalent emerging threat surfaces (or demonstrated ability to reason credibly about novel security architectures).
  • Proven ability to engage effectively with security and compliance stakeholders—not just technically, but organizationally.
  • Excellent communication skills—you can explain a Kubernetes admission webhook to a CISO and a FedRAMP control to a platform engineer, and make both conversations productive.
  • U.S. citizenship required; ability to obtain and maintain a security clearance.
