Senior Network Engineer

Enterprise / Traditional Networking

• Design, implement, configure, and support enterprise network infrastructures, including routers, switches, firewalls, and security appliances.
• Install, configure, and maintain Cisco routing and switching platforms (e.g., Cisco 7600, 6500, and 3750 series or equivalent).
• Develop and translate network security requirements and policies into detailed device configurations.
• Monitor, troubleshoot, diagnose, and resolve network performance, connectivity, and security issues.
• Manage and support Cisco ASA firewalls, VPN technologies, intrusion detection and prevention systems (IDS/IPS), and network management tools.
• Design and implement enterprise-level / ISP-grade backbone networks to support mission-critical operations.
• Understand and work with Cisco ACI concepts and operations, including fabric concepts and integration with existing network architectures.
• Understand basic physical connectivity, including fiber and Ethernet standards, optics, cabling, and patching.

Linux Networking & Systems

• Design, configure, and troubleshoot Linux-based networking (e.g., routing, bridging, VLANs, iptables/nftables, routing daemons, VPNs, firewalls) in production environments.
• Configure and maintain Linux systems used as network infrastructure components (e.g., virtual routers, VPN concentrators, security gateways, monitoring platforms).
• Utilize tools and technologies such as KVM, Ansible, Bash, Python, and related automation/orchestration frameworks to deploy and manage networked Linux systems.
• Work effectively at the intersection of traditional Cisco-style networking and Linux system administration, with a particular focus on deep Linux networking rather than general-purpose system administration alone.

Systems Engineering

• Design end-to-end systems that integrate Linux hosts, network equipment, and security components to meet defined operational and security requirements.
• Develop high-quality technical documentation, including architecture diagrams, network/system design documents, and implementation plans.
• Translate mission and operational requirements into practical, implementable network and system architectures.
• Contribute to system integration, test, and validation activities for complex networked solutions.

Additional Responsibilities

• Lead and guide small technical teams in resolving complex network and infrastructure problems.
• Provide technical direction for the operation, configuration, optimization, and maintenance of network devices and Linux-based systems.
• Ensure network and system environments meet security, compliance, and operational requirements.
• Support cellular/networked communications technologies as required by the mission.
• Learn and adapt quickly to new systems and technologies under pressure, with minimal supervision.
• Support occasional travel as required.

• Minimum of 15 years of experience in network engineering, including routing, switching, and network security in enterprise or mission-critical environments.
• Significant hands-on experience with Cisco networking and security technologies (routing, switching, firewalls, VPNs, IDS/IPS).
• Demonstrated, practical experience with Linux networking and Linux systems in an operational or production environment (beyond basic Linux system administration).
• Experience with tools/technologies such as KVM, Ansible, Bash, Python, VPN, and firewall configuration.
• Proven ability to design and document networked systems and architectures.
• Demonstrated ability to lead technical efforts and resolve complex network and infrastructure issues.
• Self-starter capable of operating independently in small teams with limited ramp-up time or mentoring resources.
• Active TS/SCI security clearance with polygraph., * Prior CNO/TAO or similar offensive/defensive cyber operations experience.
• Experience with Cisco ACI design/operations.
• Experience with cellular and other non-traditional communications technologies.
• Experience supporting mission-critical, high-availability environments with strict security requirements.
• Willingness and ability to travel as needed to support operations, testing, or deployments.
