Senior Network Engineer- Active Secret Clearance

POSITION OVERVIEW: Lead hands-on assessment, troubleshooting, remediation, and validation for enterprise network services supporting video and other time-sensitive applications. This role requires deep routing and switching expertise, advanced multicast knowledge, and the ability to trace complex transport issues across network and encryption boundaries.

What You Will Do: Assess current network architecture, device configurations, routing domains, VLANs, dependencies, and operational constraints; compare documented designs with observed behavior. Diagnose and remediate multicast and video-transport issues through IGMP/PIM analysis, routing and switching review, packet capture, and traffic-path analysis. Analyze transport across encrypted links, including MTU and fragmentation, path symmetry, QoS markings, latency, packet loss, and multicast or unicast behavior. Develop corrective actions with customer stakeholders, document proposed changes and rollback considerations, and implement approved changes during authorized maintenance windows. Plan and conduct end-to-end validation, including operational testing with relevant application and video systems; support post-implementation issue resolution. Co-lead secure network integration design with the security engineer and review high- and low-level designs, network diagrams, and future-state documentation. Maintain accurate configuration records, technical findings, validation evidence, and sustainment guidance; contribute to customer knowledge transfer.

Required Qualifications: Active CCIE Enterprise Infrastructure certification. Demonstrated expertise in enterprise routing and switching, multicast networking, packet-capture analysis, and video-transport troubleshooting. Experience analyzing IGMP and PIM behavior, multicast forwarding, VLAN and routing design, and network performance across complex paths. Ability to assess network changes, document technical findings, and validate end-to-end service behavior in production or mission-critical environments. Must be a U.S. person and hold an active Secret clearance; must meet applicable secure-facility access requirements. Ability to work on site at a secure customer facility.

Work Environment: On-site in a closed, secure network environment. Work requires disciplined
