Job description

Overview

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.

Salary

Up to $150,000.00 DOE

Minimum Qualifications
