System Security Test Engineer

We are seeking a System Security Test Engineer to support the verification and validation of complex, mission‑critical systems, including advanced networking, Voice over IP (VoIP), radio control, and Air Traffic Management systems.

This role will focus on hands‑on system security testing and the assessment and verification of security controls against NIST SP 800-53 Revision 5 requirements. The ideal candidate combines a strong systems‑testing background with practical cybersecurity knowledge and experience validating security controls in integrated hardware, software, and network environments.

Key Responsibilities

• Plan, develop, execute, and document system security test activities for complex integrated systems.
• Perform hands‑on testing of advanced networking systems, VoIP systems, radio control equipment, and/or Air Traffic Management systems.
• Assess and verify implementation of NIST SP 800-53 Rev. 5 security controls.
• Perform security‑control testing within key NIST control families, including:

• Access Control (AC)
• Configuration Management (CM)
• Identification and Authentication (IA)
• System and Communications Protection (SC)
• 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.

Required Qualifications

• 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.
