Job Description
Chief Security Architect – Developer Experience
Leidos
• 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.
Job 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.
