PeopleTec is currently seeking an Avionics Cyber Test Engineer to support our Huntsville, AL location.

We are supporting the Test & Evaluation (T&E) of an aviation platformutilizinga deterministic Ethernet-based Time-Sensitive Networking (TSN) Data Distribution System (DDS) architecturewithsecure, resilient, and real-time mission communications. We are seeking engineers who thrive in complex integration environments and are passionate about advancing cybersecurity testing and resiliency for airborne platforms and mission systems.

As Cybersecurity Engineer, you will support cybersecurity verification, validation, and certification activities for TSN-enabled aviation platform networks and DDS architectures. You will perform cybersecurity testing within integrated lab environments using lab-grade hardware and representative avionics systems to evaluate cyber resiliency, network security, and deterministic communications performance.

You will work closely with systems engineering, avionics integration and network architectureto assess vulnerabilities,validatemitigations, and support platform cybersecurity certification effortsduring thedevelopmentof the architecture from the Systems Integrator.

Key Responsibilities:

• Conduct offensive cybersecurity testing against Ethernet-based TSN and DDS architectures.
• Perform vulnerability assessments, penetration testing, protocol fuzzing, and adversarial testing of integrated avionics network systems.
• Support cybersecurity integration and validation activities withinaSystem Integration Lab (SIL)utilizinglab-grade hardware and representative avionics components.
• Evaluate network resiliency under degraded, malicious, and abnormal traffic conditions.
• Analyze TSN synchronization, traffic scheduling, latency, and deterministic network behavior under adversarial conditions.
• Support transition from SIL-based testing to platform-level integration and System Test Integration Lab (STIL) activities.
• Develop cyber test procedures, technical reports, risk assessments, and certification artifacts.
• Develop custom scripts and tooling to automate cybersecurity test activities and traffic analysis.

Required Skills/Experience:

• 12+ years of experience in offensive cybersecurity engineering, network penetration testing, embedded systems testing, or cyber resiliency assessment.
• Experience with Ethernet networking, packet analysis, and cybersecurity test methodologiesutilizingWireshark,Scapy, Zeek, Kali Linux,Ghidra, or protocol fuzzing frameworks.
• Familiarity with avionics data distribution systems and airborne network architecturesutilizingbus protocols such as CAN Bus, MIL-STD-1553, ARINC 429, ARINC 664 Part 7 (AFDX), and Time-Sensitive Networking (TSN).
• Experience supporting cybersecurity testing, integration, or resiliency assessments on avionics or mission platform environments is highly desired.
• Experience with scripting and development languages such as Python, C, or C++.
• Strong communicationskills with the ability to create detailed technical reports and briefings.
• Must be willing to travelto various technical events and conferences as needed (estimated 10% per year).
• Must be a U.S. Citizen
• An active DoD Secret clearance is required to perform this work. Candidates are required to have an active Secret clearance upon hire, and the ability to maintain this level of clearance during their employment.

Education Requirements:

• Bachelors degree in Cybersecurity, Computer Engineering, Electrical Engineering, Computer Science, Aerospace Engineering, or related discipline.

Desired Skills:

• 10+ years of relevant experience in cybersecurity engineering, avionics integration, platform test and evaluation, or offensive cyber testing within defense or aerospace environments.
• Experience performing vulnerability assessments, penetration testing, protocol analysis, or cyber resiliency testing against embedded or integrated platform systems.
• Ability to lead technical discussions andprovidecybersecurity insightstocross-functional teams.
