Sr. Network Engineer (Cisco & Network Security)

• →Develop, plan, and implement scalable network solutions, new network layouts, and upgrades.
• →Install, configure, and maintain network hardware (routers, switches, firewalls) and software.
• →Implement and manage network security measures, including firewall rules, access controls, and security protocols to protect data.
• →Resolve network issues.
• →Monitor network health, analyze traffic patterns, and improve visibility through metrics and alerting.
• →Create and maintain network documentation, policies, and procedures.

Provides assistance in all aspects of network management from network design through implementation, maintenance, and upgrading of existing networks; Analyzes design, specifications, and related documents; Implements communication system requirements to support the distributed functionality of a software engineering environment; Analyzes network characteristics (e.g. traffic connect time, transmission speeds, packet sizes and throughput), troubleshoots problems and recommends procurement of and/or modifications to network components.

The Level 3 Network Engineer shall possess the following capabilities:

• Minimize network latency and maximize data throughput through design analysis and network performance monitoring tools
• Develops algorithms used in modules or incorporated into models associated with the research and development of technologies and systems.
• Ensures that all material received is inspected for evidence of tampering and, if any is found, submits a report of suspected physical incident immediately
• Configure and maintain organization's network diagrams and accreditations.
• Integrate hardware and software to satisfy ISO 9000 requirements and other DoD/IC regulations.
• Design, integrate, test, and deploy solutions to established network issues.
• Optimize end-to-end system performance and dataflow management.
• Coordinate with appropriate dataflow organizations and end-customer recipients, follow-on data repositories and tasking organizations and mitigate potential adverse impacts on system-wide dataflow
• Implement specific network solutions to support server requirements to include load-balancing, VPN’s, firewall contexts, Traffic Shapping Voice over IP (VOIP), GRE Tunneling, IP Security (IPSec) IP Encryption and Media over IP (MoIP), and network address translation (NAT) where appropriate
• Coordinate with the system engineering and dataflow efforts to ensure proper mission operations to minimize down time.
• Design solutions, integrate, configure, deploy, test and provide ongoing maintenance for numerous types of network devices, interfaces and methodologies
• Applies Network Acceleration techniques such as Riverbed.
• Conducts inventories as directed (e.g., semiannually/annually)
• Reports any known or suspected COMSEC incidents immediately
• Perform configuration, test, deployment, and maintenance to all network equipment.
• Validate new and existing dataflow and data formats,
• Manage assigned tasks and provide guidance to junior Network Engineers.
• Facilitate the implementation of high-speed, scalable, fault-tolerant network topologies as applicable to WAN and LAN design.
• Configure and optimize the network to connect various front-end and back-end components
• Lead large efforts of dynamic requirements and scale
• Resolve complex network problems, operate network analyzers, WAN test equipment and network simulators
• Assists System engineers and cross organizational teams to define requirements.

• Twelve (12) years’ experience in programs and contracts of similar scope, type, and complexity is required. Bachelor’s degree in engineering from an accredited college or university is required. Four (4) years of additional network engineering experience may be substituted for a bachelor’s degree.
• Certifications: An IAT level III baseline certification as defined by DoD 8570.01-M is required.
• Minimum of 3 years as a Network Engineer (within the last 3 years).
• Proficient with Linux. Linux system administration experience is a plus.
• CCNA or CCNP certification.
• Security+ certification.

• Should have working knowledge, able to use and or support, with some (preferably most) of the following resources and tools.
• Juniper and Cisco routers, switches, and firewalls
• Palo Alto firewalls
• Dell and HPE Linux servers
