• Assess and verify implementation of NIST SP 800-53 Rev. 5 security controls.
• Perform security-control testing within key NIST control families, including:

o Access Control (AC) o Configuration Management (CM) o Identification and Authentication (IA) o System and Communications Protection (SC) o System and Information Integrity (SI)

• Develop detailed security test procedures, test cases, test scripts, expected results, and supporting documentation.
• Execute security verification testing in integrated system and lab environments.
• Validate user access, authentication, authorization, account management, privilege restrictions, configuration controls, communications protections, and system-integrity mechanisms.
• Analyze test results and identify security-control deficiencies, unexpected system behavior, and potential vulnerabilities.
• Document defects and security findings with clear supporting evidence and reproducible test steps.
• Work closely with systems engineering, software, network, cybersecurity, and test teams to troubleshoot and resolve issues.
• Perform regression testing following security-related changes, patches, configuration updates, or defect remediation.
• Support formal test events, customer demonstrations, acceptance testing, and technical reviews.
• Maintain traceability between security requirements, NIST controls, test procedures, results, and identified deficiencies.

• Bachelor’s degree in Computer Science, Cybersecurity, Electrical/Computer Engineering, Information Technology, or related technical discipline, or equivalent relevant experience.
• Hands-on system test experience involving advanced networking, VoIP, radio control equipment, and/or Air Traffic Management systems.
• Practical experience assessing or verifying NIST SP 800-53 Rev. 5 security controls.
• Experience with AC, CM, IA, SC, and SI control families.
• Strong understanding of networking concepts and protocols, including TCP/IP and secure network communications.
• Experience developing and executing formal test procedures and documenting results.
• Strong troubleshooting and root-cause-analysis skills.
• Ability to work across hardware, software, networking, and cybersecurity teams.
• Strong technical documentation and communication skills.

Preferred Qualifications Experience with FAA or other safety/mission-critical systems, Linux and Windows environments, network-analysis tools such as Wireshark, vulnerability/security testing tools, requirements traceability, Jira or similar defect-management systems, and formal FAT/SAT or customer acceptance testing would be highly desirable.

Our client offers highly competitive compensation packages, comprehensive benefits, and a collaborative, people-first culture that promotes innovation, professional growth, and long-term career development. We are committed to creating an environment where employees are empowered to make an impact, work alongside highly talented teams, and contribute to meaningful, mission-critical initiatives in a supportive and forward-thinking workplace.
