Systems Security Engineer

Nightwing Intelligence Solutions, LLC is building secure capabilities for forward-deployed DoD tactical systems and supporting authorization efforts with security artifacts that hold up in real environments. In a hybrid role based in Huntsville, AL, the Systems Security Engineer (SSE) will translate DoD security requirements into implementable technical solutions, working hands-on with actual platforms in test labs and operational environments.

What you’ll do

• Integrate products into security architectures for tactical systems.
• Develop security solutions that fit forward-deployed constraints such as SWaP limitations and real-time requirements.
• Create security artifacts for operational systems, including Attack Trees, Key Management Plans, and System Security Plans for fielded platforms.
• Map security requirements across frameworks including 800-53, Anti-Tamper, Cyber Survivability, and Zero Trust, then translate them into technical implementations.
• Coordinate with platform security personnel and accreditation authorities to support authorization processes.

What you bring

• Active Secret or TS clearance strongly preferred.
• Experience with tactical and embedded DoD systems.
• Security architecture design experience for resource-constrained and real-time systems.
• Understanding of hardware security constraints in tactical environments.
• Experience integrating commercial security products into government platforms or weapon systems.
• Knowledge of operational security considerations for forward-deployed systems.
• Deep knowledge of DoD cybersecurity requirements, frameworks, and processes including RMF, Anti-Tamper, Cyber Survivability, and Zero Trust.
• Experience developing security artifacts beyond checkbox compliance.
• Understanding of cryptographic implementations and key management in operational contexts.
• Ability to map security requirements across different frameworks.
• Experience interfacing with platform security engineering and accreditation authorities.
• Strong technical writing and documentation skills.
• Ability to communicate effectively with both technical teams and government stakeholders.
• Experience working on-platform or in test labs with actual hardware and software.
• U.S. Citizenship is required.
• Must meet requirements to obtain and maintain a Secret government security clearance.

Relevant technical experience

• Hands-on security or software integration experience with tactical platforms, such as radar systems, missile defense systems, avionics/flight control, C4ISR equipment, electronic warfare systems, tactical communication systems, and other forward-deployed mission systems.
• Familiarity with TPM and Secure Boot technologies implementation.
• OS internals familiarity in embedded or tactical contexts (Linux and/or Windows).
• Real-time operating system (RTOS) security considerations.
• Security testing and assessment experience for embedded systems, including penetration testing and vulnerability assessment.
• Knowledge of security assessment tools such as static/dynamic analysis and fuzzing applicable to tactical systems.
• Experience with security requirements for embedded systems or kernel/driver software.
• Ability to navigate complex DoD security requirements while delivering practical, implementable solutions.
• Experience translating between operational/engineering needs and compliance/accreditation requirements.
