## Description

We are seeking a Senior Ethernet Network Architect to design, develop, and manage advanced Ethernet network architectures for military ground vehicles and defense vehicle systems. This role supports new and existing vehicle platforms, leveraging Model-Based Systems Engineering (MBSE), Cameo, SysML, Time-Sensitive Networking (TSN), VLANs, Quality of Service (QoS), and Ethernet security standards to enable reliable, deterministic, and secure communications across software-defined vehicle networks., * Develop and maintain Ethernet network architectures for new and existing military ground vehicle platforms, ensuring compliance with customer and internal requirements.

 * Create network architecture diagrams and reference designs using industry evaluations, engineering trade studies, and MBSE methodologies.
 * Evaluate, refine, and update network architectures as system requirements, interface definitions, and design information evolve.
 * Develop, capture, and review system and subsystem connectivity diagrams using SysML Internal Block Diagrams (IBDs), Block Definition Diagrams (BDDs), and electrical schematics.
 * Identify, document, track, and manage network interface attributes and requirements within MBSE models using Cameo.
 * Collaborate with software, cybersecurity, data, hardware, and systems engineering teams to integrate secure, reliable Ethernet communications across vehicle subsystems.
 * Define and communicate Ethernet interface requirements, network design constraints, and architecture specifications to engineering teams and external vendors.
 * Review lower-level hardware and software designs to verify compliance with approved network architectures and traceability to higher-level system requirements.
 * Evaluate competing technical requirements and develop architecture trade-offs to support system performance, reliability, cybersecurity, and deterministic communications.
 * Serve as the primary technical point of contact for Ethernet network architecture across multiple concurrent vehicle development programs.
