Network Engineer, Lead Security Clearance

Position: Network Engineer, Lead with Security Clearance
Job Number: R0228835 Network Engineer, Lead

The Opportunity:

A well-designed network is critical to move data and enable Department of Defense ( DoD ) and Intelligence Community ( IC ) organizations to achieve their missions, but how can an organization make sure their network will fit their evolving needs? Crafting the right network, with the right equipment, sof tware, and architecture, requires a combination of advanced technical skill, mission understanding, and strategic foresight.

That's why we need a seasoned senior network engineer like you who knows how to develop, secure, and modernize the exact network infrastructure the DoD and IC depend on to accomplish their missions worldwide. As a senior network engineer on our team, you'll leverage your experience in enterprise network design and architecture, system interoperability, OSI and network transport layers, multi-protocol label switching ( MPLS ) , border gateway protocol ( BGP ) , and virtual routing and forwarding ( VRF ) to strengthen the nation's defense posture and enable real-time collaboration across secure domains.

You'll engineer, upgrade, and optimize enterprise-wide infrastructure, troubleshoot and resolve complex routing and performance issues, c ond uct architecture analyses, and implement high-availability designs to enhance security, reliability, and mission readiness for national systems supporting multiple CONUS locations. You'll apply your expertise in advanced routing and switching, integration of encryption and key management devices, network architecture design, IP engineering, segmentation, and network transport optimization as you lead and mentor engineers across multiple enclaves-helping the DoD and IC evolve and deploy next-generation capabilities that enhance secure communications, accelerate mission execution, and strengthen cyber resilience.

Your knowledge of network protocols, Cisco and Palo Alto enterprise technologies, emerging cloud-based architectures, and hybrid network configurations will be vital as you drive modernization efforts and optimize client operations. Leveraging your experience in cryptographic integration, key management, Cisco ISE, sof tware-defined networking ( SDN ) , firewall configuration, VMWare virtual networking, Solar Winds enterprise monitoring, and optical transport systems, you'll act as a t rus ted technical advisor to mission stakeholders, ensuring engineering rigor, compliance with RMF and NIST 800-53 controls, and sustained operational excellence across sensitive environments.

Advance your career with us as we help modernize and defend the DoD and Intelligence Community's secure network infrastructure, enabling warfighters, analysts, and decision-makers to operate, collaborate, and protect national interests with confidence. Join us. The world can't wait. You Have:
* 10+ years of experience with enterprise network architecture, engineering, and operations support for mission-critical systems within classified and DoD environments

* Experience supporting Operations and Maintenance ( O & M ) engineering activities, including system patching, change control, lifecycle management, and capacity optimization

* Experience developing engineering documentation, network baselines, and standardized deployment processes in alignment with Risk Management Framework ( RMF ) , NIST 800-53, and organizational compliance requirements

* Experience designing, implementing, and maintaining enterprise network monitoring infrastructures using tools such as Solar Winds, to ensure system availability, performance visibility, and configuration compliance

* Knowledge of core network protocols and technologies such as TCP / IP, SNMP, DHCP, DNS, and virtualized environments, including VMware ESXi

* Knowledge of Cisco enterprise technologies, including Cisco ISE, advanced routing protocols such as EIGRP, OSPF, and BGP, and complex Layer 2 / 3 switching such as VLANs, STP, VTP, and Ether Channel

* Ability to diagnose and resolve complex network incidents across WAN, LAN, and hybrid environments through advanced root-cause analysis and packet inspection

* TS/SCI clearance with a polygraph
* Bachelor's…
