What You Will Do:

The Security Assessor supports security and privacy control assessments for public‑sector systems by evaluating control effectiveness, validating evidence, and contributing to formal assessment documentation under the direction of a Senior Security Assessor.

This role is primarily focused on assessment execution and documentation; however, it also provides exposure to more technical aspects of system architecture and control implementation. Candidates should demonstrate curiosity and interest in expanding their skillset toward security engineering, automation, and emerging AI‑enabled approaches to compliance and assessment activities. 

This role focuses on assessment execution and documentation, not system engineering or operational security responsibilities.

Key job responsibilities include the following:

  • Perform security and privacy control assessments in accordance with established assessment plans

  • Review security documentation and technical evidence

  • Validate control implementation through:

    • Evidence inspection

    • Architecture and system documentation review

    • Interviews with system owners and technical staff

  • Contribute to assessment artifacts, including:

    • SSP updates

    • SARs

    • ISRAs

    • POA&Ms

  • Document assessment results and clearly articulate control gaps and risks

  • Maintain assessment independence and objectivity

  • Identify opportunities to improve assessment efficiency through standardization, tooling, or automation of evidence collection and validation 

  • Support the use of data-driven or AI-assisted techniques to enhance analysis, traceability, and reporting over time 


What You Will Need:

  • Minimum of THREE (3) years of overall work experience ideally in supporting security control assessments, audits, or authorization activities

  • Bachelors Degree from an accredited university

  • US Citizenship is contractually required

  • Hands‑on experience contributing to formal security assessment documentation (SSPs, SARs, POA&Ms, or equivalents)

  • Working knowledge of NIST SP 800‑53 security and privacy controls

  • Understanding of risk‑based assessment concepts

  • Ability to analyze assessment evidence and clearly document findings


What Would Be Nice To Have:

  • Experience supporting government or other regulated environments

  • Exposure to CMS, healthcare, or public‑sector security compliance frameworks

  • Familiarity with A&A, RMF, or Security Control Assessment processes

  • Relevant certifications (CISA, CISSP, CISM, Security+, or similar)

  • Prior background in or exposure to security engineering, cloud security, or system implementation 

  • Familiarity with modern architectures (cloud platforms, IAM, logging/monitoring, APIs) and how controls are implemented in those environments 

  • Exposure to automation tools, scripting, or GRC platforms supporting assessment or compliance activities 

  • Interest in applying AI/automation to improve audit readiness, evidence analysis, or continuous monitoring processes


What We Offer:

Benefits include:
