• 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.

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