  • Deep hands-on experience authoring and maintaining System Security Plans (SSPs) aligned to NIST 800-171 and NIST 800-53 is required.
  • Demonstrated experience supporting systems through ATO efforts, formal security assessments, or CMMC readiness activities is required.
  • Experience managing POA&Ms, coordinating remediation tracking, and running structured evidence collection cycles is required.
  • A strong background serving as a primary point of contact for auditors, assessors, and compliance stakeholders is required.
  • Proven ability to build and maintain policy libraries, standards, and standard operating procedures aligned to a formal control framework is required.
  • Ability to read and interpret architecture diagrams, infrastructure-as-code, and technical documentation well enough to validate that control narratives reflect implemented reality is required.
  • Working knowledge of AWS and cloud-native environments, including EKS, IAM, logging, encryption, and cloud security controls, is required.
  • Exceptional attention to detail and the ability to identify vague, conflicting, or incomplete documentation and drive clarity are required.

  • Manage POA&Ms, including documenting gaps, tracking remediation progress, and maintaining visibility into open items.
  • Coordinate and run evidence collection cycles in support of internal reviews, external assessments, and audit activities.
  • Serve as the primary compliance point of contact for internal auditors, external assessors, and compliance stakeholders.
  • Partner with platform, cloud, and security engineers to validate that documented control narratives accurately reflect implemented infrastructure and operational practices.
  • Review architecture diagrams, infrastructure-as-code, technical diagrams, and engineering documentation to ensure compliance materials remain accurate and defensible.
  • Ensure consistency, traceability, and quality across compliance documentation and supporting artifacts.
  • Identify documentation gaps, policy inconsistencies, or control narrative issues early and drive them to resolution.
  • Support the maturation of repeatable compliance processes that strengthen audit readiness over time.

Desired Qualifications

  • Experience supporting CMMC Level 2 preparation, assessment, or sustainment activities.
  • Background contributing to FedRAMP or DoD ATO packages.
  • Experience working in highly technical cloud or platform environments where security controls must be mapped directly to operational systems.
  • Familiarity with evidence management, control traceability, and structured documentation practices in regulated environments.

  • Ability to operate effectively in an environment where compliance maturity is actively being built and refined.

About the Company

Peraton

Runs and secures technology for federal agencies

Peraton builds and runs secure technology for American defense, intelligence, space, and civilian agencies, from military networks to satellite ground stations. In 2025, the Federal Aviation Administration chose it to manage the overhaul of the nation's air traffic control system, replacing copper wiring with fiber and upgrading radar and radios. Its engineers, many holding security clearances, run and defend agency networks and data centers, write mission software, and operate space and communications systems, and agencies pay for this work through multiyear contracts. Peraton was formed in 2017, when private-equity firm Veritas Capital bought Harris Corporation's government IT business, and is based in Reston, Virginia.
