## Description

Help define the future of flight at GE Aerospace! As Principal Systems Architect - Avionics Networking, you will be the senior technical leader for GE Aerospace's avionics networking portfolio within the ION (Input/Output & Networking) organization. You will shape the architecture, technology roadmap, and certification approach for deterministic airborne networks supporting civil and military aircraft platforms.

You will serve as Design Technical Authority (DTA) for avionics networking products, governing architecture decisions, technical baselines, and the DO-254/DO-178C certification approach, so that our solutions are competitive, reusable across programs, and certifiable. Your decisions will set the technical direction for engineering teams and customers across the portfolio., * Define and maintain the architecture and technology roadmap for the avionics networking portfolio, including ARINC 664 (AFDX), Time-Sensitive Networking (TSN), and related Ethernet-based avionics networks.

 * Serve as Design Technical Authority (DTA), providing final technical decisions on architecture, requirements baselines, and design trades for avionics networking products.
 * Own the certification approach for networking products (ARP4754A, DO-254, DO-178C DAL A, DO-297 as applicable), including hardware/software partitioning and engagement in SOIs, audits, and closure of findings.
 * Provide deep technical authority on deterministic networking, including ARINC 664 Part 7 and TSN (IEEE 802.1AS/Qbv/Qci/CB), to guide protocol, hardware, and software design.
 * Drive architecture reuse and commonality across programs while managing customer-specific requirements in a disciplined, controlled way.
 * Lead technical reviews, including architecture, requirements, design, and code reviews, and drive resolution of critical technical risks and trade studies.
 * Partner with Engineering Project Managers, technical managers, and subject matter experts to align technical plans with schedule, cost, and resource commitments.
 * Assist project and program leadership in resolving engineering issues related to design, validation, integration, verification, safety, certification, closure, and field support.
 * Represent GE Aerospace avionics networking with customers, airframers, suppliers, and certification authorities. Support business development, RFP/RFI responses, and competitive positioning.
 * Analyze market and technology trends, competitive offerings, and obsolescence drivers to inform the technology roadmap and IRAD priorities.
 * Mentor senior engineers and subject matter experts, and build networking technical competency across the organization.
 * Travel up to 15%.
