Senior Network Engineer

We are seeking a Senior Network Engineer to design, engineer, administer, and support mission-critical classified network services across multiple enclaves and locations. This role ensures high availability, strong security posture, and rapid recovery objectives while delivering reliable connectivity and operational excellence across a complex enterprise environment. 

Responsibilities

• Engineer, administer, and support classified network infrastructure (routing, switching, segmentation, addressing, traffic flows, and topology management).
• Design and develop architectural models for classified networks; implement secure, effective solutions aligned to approved standards.
• Configure, document, and manage network devices and topologies; maintain accurate logical/physical diagrams and system documentation/SOPs.
• Monitor and respond to network/system alerts; perform incident troubleshooting, remediation, and reporting to maintain availability and performance.
• Support operations across a distributed footprint, including data center network connectivity and coordination with other support centers.
• Participate in change and configuration management: validate changes in a lab/replica environment, document implementation/backout steps, and follow change control processes.
• Support classified connectivity requirements, including interfaces to external classified networks (as applicable to the environment).
• Partner with systems, security, and operations teams to ensure solutions meet or exceed security standards and compliance requirements.
• Provide escalation support beyond the Service Desk and contribute to continuous performance improvement initiatives.
• Provide on-site support at primary facilities and travel as needed for incident resolution and deployments.

Required

• Bachelor’s degree in Computer Science, Information Technology, Engineering, or a related field (or equivalent practical experience).
• 10+ years of network engineering experience in enterprise environments. 
• Experience designing and supporting complex routed/switched networks (LAN/WAN), network segmentation, and enterprise addressing/routing schemes.
• Strong troubleshooting skills across connectivity and performance issues in production environments with strict uptime requirements.
• Hands-on experience with network monitoring/alerting, incident response, and producing clear engineering documentation/SOPs.
• Experience working within formal change control / configuration management processes (lab validation, implementation plans, backout procedures, documentation updates).
• Active TS/clearance and ability to comply with all onsite and security requirements.
   

Preferred

• Cisco and/or Juniper enterprise experience (routing/switching), including large-scale operations.
• Experience supporting high-assurance/classified network environments, including encryption/crypto ecosystems and secure network integrations.
• Familiarity with environments using Type-1 encryptors, cross-domain workflows, and tightly controlled removable media processes.
• Certifications such as CCNP/CCIE, JNCIP/JNCIE, Security+ (or equivalent).
• Experience supporting data center environments and integrated infrastructure stacks (compute/virtualization/storage) in support of network services.
