CACI is seeking a Network Engineer who will provide 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.

• 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, VPNs, firewall contexts, Traffic Shaping 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 downtime.
• Design solutions, integrate, configure, deploy, test and provide ongoing maintenance for numerous types of network devices, interfaces and methodologies.
• Apply Network Acceleration techniques such as Riverbed.
• Conduct inventories as directed (e.g., semiannually/annually).
• Report 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.
• Assist System engineers and cross‑organizational teams to define requirements.

• Active TS/SCI with Polygraphic clearance.
• Proficiency with routing and switching technologies.
• Familiarity with firewalls, VPNs, IDS/IPS, and network security standards.
• Experience with cloud networking.
• Skilled in troubleshooting complex network issues and developing solutions.
• Python programming.
• Ansible.
• IAT level 3 certification required.
• 12 years’ experience in programs and contracts of similar scope, type, and complexity.
• Bachelor’s degree in engineering from an accredited college or university; or 4 years of additional network engineering experience may substitute for a bachelor’s degree.
• Certification:
  DoD 8570.01‑M IAT level III baseline certification.
