## Description

The Secure Network Engineer will provide technical leadership and hands-on expertise in secure networking for critical ground infrastructure systems supporting national security missions. This role ensures resilient, compliant, and cyber-secure networking across development, integration, testing, and operational phases. The engineer will directly support program management, systems engineering, cybersecurity, integration and test, and operations., Program & Technical Leadership

 * Attend and lead technical and program reviews, working groups, and design milestones (SRR, PDR, CDR, ORR).
 * Ensure compliance with applicable engineering and quality standards, including IEEE 15288.x, SAE AS9100, AS6500, and MIL-STD-882E.
 * Provide technical deliverables and documentation related to secure networking.

Ground Transition & Integration

 * Support secure networking during hardware/software integration and ground system transitions.
 * Establish and maintain network connectivity, security controls, and cryptographic device management.
 * Ensure proper handling of COMSEC devices, spares, and keying materials.

Program Management

 * Provide secure networking inputs to project schedules and integrated master plans.
 * Track milestones, risks, and deliverables related to networking security activities.

Systems Engineering

 * Lead or support requirements definition, risk management, and technical performance tracking.
 * Develop and maintain networking artifacts within model-based systems engineering (MBSE) environments.
 * Support verification, validation, and system safety planning for secure networking elements.
 * Deliver sustainment and maintenance planning for secure networking infrastructure.

Integration & Test

 * Develop, review, and maintain interface control documents for networking systems.
 * Support integration and test activities with vendors and mission partners.
 * Troubleshoot connectivity issues and ensure interoperability across systems and mission partners.
 * Participate in test readiness reviews and resolve findings.

Cybersecurity

 * Support cybersecurity testing and evaluation of ground systems.
 * Develop and maintain cybersecurity body of evidence (e.g., workforce rosters, PPS matrices, STIGs, compliance reports, network diagrams, device configs).
 * Conduct vulnerability assessments, compliance scans, and mitigation activities.
 * Protect systems against TEMPEST-related threats and information leakage.

Operations & Sustainment

 * Design, plan, and execute secure network infrastructure installations at operational facilities.
 * Maintain ground system infrastructure with updated configurations.
 * Support nominal and backup operations of ground elements as the secure networking lead.

Travel Requirements

 * Up to 25% travel to program offices, operational facilities, and contractor/vendor sites.
