About The Position

PeopleTec is currently seeking a Network Administrator Lead / Senior Network Engineer (Digital Backbone / TSN) to support our Huntsville, AL location. We are supporting the integration, verification, and test of next-generation aviation and mission systems utilizing deterministic Ethernet-based Time-Sensitive Networking (TSN), Time-Triggered Ethernet (TTE) and Digital Backbone (DBB) architectures within Hardware-in-the-Loop (HWIL) and Software-in-the-Loop (SWIL) environments. We are seeking engineers who thrive in complex integration environments and are passionate about advancing secure, resilient, and interoperable mission systems for airborne platforms. As a Senior Network Engineer, you will design, integrate, secure, and validate deterministic network infrastructures supporting aviation mission systems, digital engineering environments, and distributed platform integration activities. You will work closely with systems engineering, avionics integration, cybersecurity, and modeling & simulation teams to develop and maintain high-performance network architectures supporting real-time mission communications and platform interoperability.
