About The Position

Leidos is hiring a Senior Network Engineer for its Cyber & Analytics Business Area, Key Management & Analytics Division, to support critical national-security missions. The role provides senior-level engineering expertise throughout the network and telecommunications lifecycle, including architecture, design, integration, deployment, operations, optimization, and sustainment. The engineer designs and deploys secure mission networks, configures and maintains network infrastructure, resolves complex technical issues, and integrates emerging technologies. The position also involves coordinating with systems engineers, cybersecurity professionals, network operations centers, telecommunications providers, and mission partners, while providing technical leadership to less-experienced network engineers. This is a full-time, on-site position in a secure mission environment; remote work is not available. Candidates must have an active TS/SCI clearance with Polygraph. The stated pay range is $116,350 to $210,325.

Requirements

Twelve years of experience as a Network Engineer on programs and contracts of similar scope, type, and complexity.
Bachelor's degree in a technical discipline from an accredited college or university, or five years of Network Engineering experience as a substitute.
Active TS/SCI clearance with Polygraph and ability to work full-time on site in a secure mission environment.
Current Cisco Certified Network Professional (CCNP) certification in an applicable networking discipline, or an equivalent certification approved by the program.
Demonstrated experience designing, configuring, implementing, troubleshooting, and optimizing complex network and telecommunications environments, including routing protocols, BGP, policy-based routing, tunneling, IPsec, NAT, WAN technologies, traffic management, and network performance analysis.
Experience configuring, testing, installing, troubleshooting, and maintaining enterprise network and security infrastructure, including routers, firewalls, intrusion detection systems, cryptographic devices, and related network technologies.
Ability to diagnose and resolve complex network and telecommunications problems, develop and document technical solutions, and provide technical guidance and leadership to junior and mid-level Network Engineers.
