Network Protocols & Simulation Subject Matter Expert
Candidates must be able to obtain and/or maintain a Department of Defense Secret Security Clearance as a condition and continuation of employment
Description
We are seeking a Subject Matter Expert (SME) in Network Protocols and Simulation to join an Advanced Engineering Group supporting complex, mission-critical network architecture analysis and design. This role serves as the technical lead for designing, modeling, and analyzing high‑fidelity network architectures using Riverbed Modeler (OPNET).
The successful candidate will simulate, troubleshoot, and optimize complex network scenarios with a strong emphasis on Physical (L1), Data Link (L2), and Network (L3) layers, including physical medium modeling (Layer 0). This is a remote position with travel.
Key Responsibilities
Network Simulation (OPNET / Riverbed):
Create, execute, and analyze high-fidelity discrete-event simulations using Riverbed Modeler to evaluate network performance, reliability, scalability, and resiliency.
Protocol Development & Analysis:
Serve as a technical SME in routing, switching, and transport protocols. Modify existing models or develop custom models using C/C++ to simulate proprietary, emerging, or complex protocols.
OSI Layers 0-3 Focus:
Perform deep technical analysis across:
Layer 0/1: physical media characteristics, signal propagation, modulation, bit error rates
Layer 2: MAC protocols, switching, VLANs
Layer 3: routing and transport technologies such as BGP, OSPF, EIGRP, MPLS, IPv6
Performance Optimization:
Analyze simulation outputs to identify bottlenecks, packet loss, latency, and capacity constraints; develop "what‑if" scenarios to improve network architectures prior to deployment.
Architecture Modeling:
Develop detailed LAN, WAN, and wireless network topologies to validate designs before hardware implementation.
Technical Reporting:
Document simulation methodologies, assumptions, scenarios, and results in detailed technical reports for stakeholder review.
