The Network Projects Lead will be responsible for advancing enterprise network innovation through the execution of strategic design and implementation efforts. This role will lead upcoming and future engineering projects such as Network Segmentation/C2C, enterprise Wi-Fi modernization, and other network transformation initiatives that support the evolution of the DES enterprise architecture and improve security, reliability, and mission outcomes.

Must be willing to commute to Ft. Meade, MD 2 days per week. This position requires an active DoD Secret clearance.

Primary Responsibilities

• Lead a network project engineering team responsible for planning, designing, and implementing enterprise network modernization initiatives that improve the security, scalability, resiliency, and performance of the parent network environment.
• Drive strategic engineering projects from concept through implementation, including architecture evaluation, requirements analysis, dependency identification, design coordination, planning, execution, validation, and transition to operations.
• Lead current and future enterprise network initiatives such as Network Segmentation/C2C, enterprise Wi-Fi modernization, IPv4/IPv6 transition, network optimization, connectivity consolidation, lifecycle replacement, automation, and related architecture improvement efforts.
• Provide technical leadership, mentoring, and day-to-day direction to network engineers, administrators, and analysts while organizing team priorities, maintaining accountability, and ensuring execution against aggressive timelines.
• Evaluate current network architecture, identify gaps or improvement opportunities, estimate level of effort, assess implementation risk, and develop practical engineering plans to improve enterprise capabilities.
• Develop and manage implementation plans, schedules, cutover strategies, contingency plans, rollback procedures, validation steps, stakeholder communications, and change documentation for mission-critical network changes.
• Lead Network Segmentation/C2C planning and implementation, including data-flow mapping, firewall rule set and ACL review, routing and security policy coordination, cutover sequencing, validation, and stakeholder approval.
• Partners with architecture, cybersecurity, operations, project management, and technical SME teams to resolve blockers, manage dependencies, reduce delivery risk, and ensure network projects are executed end-to-end.
• Continuously improving engineering processes, documentation standards, implementation playbooks, and execution models to accelerate delivery, reduce rework, improve operational handoff, and lower sustainment burden., DevOps Firewall Equities Scheduling Operations Automation Purchasing Upskilling Encryption Market Data End Systems Coordinating Cryptography ISO/IEC 15288 Load Balancing Key Management Network Routing ISO 9000 Series Traffic Shaping Ancient History Computer Science Security Systems Network Diagrams Analytical Method Program Management Telecommunications Wide Area Networks Data Center Design Collection Systems Systems Engineering Networking Hardware Local Area Networks Network Engineering Time Off Management Security Engineering Engineering Analysis Signals Intelligence Design Specifications Business Requirements Information Assurance Engineering Management IAT Level I Certification Computer Network Operations Juniper Network Technologies Virtual Private Networks (VPN) Cisco Certified Network Associate Internet Protocol Security (IP SEC) Top Secret-Sensitive Compartmented Information (TS/SCI Clearance) +0
