This role focuses on architecting high-bandwidth, ultra-reliable Ethernet Routing Engines and PCIe subsystems that serve as the primary data fabric for Autonomous Driving (AD) and Cockpit controllers. The ideal candidate will bridge the gap between high-speed data center-grade throughput and the rigorous Safety (ISO 26262) and Deterministic Networking requirements of the automotive industry. ### Responsibilities Automotive Ethernet Routing: Architect L2/L3 switch fabrics supporting Time-Sensitive Networking (TSN) standards (e.g., IEEE 802.1AS, 802.1Qbv, 802.1Qbu) to ensure deterministic latency for safety-critical traffic. ### PCIe Backbone Architecture Define PCIe Gen 5/6 integration for high-speed chip-to-chip connectivity between SoCs, AI accelerators, and storage, including support for SR-IOV to virtualize resources across multiple Virtual Machines (VMs). ### Functional Safety (ASIL) Integrate hardware safety mechanisms (ECC, Parity, BIST, and End-to-End protection) to meet ASIL-B/D requirements within the routing engine and bus fabrics. ### Zonal Interconnect & Bus Fabric Design the interface between Ethernet/PCIe controllers and internal NoC/CHI fabrics, ensuring efficient data movement for ADAS sensors (Camera, LiDAR) and telemetry. ### Virtualization & Security Architect hardware-assisted isolation and Secure On-board Communication (SecOC) to protect the vehicle network from cyber threats while allowing shared access to network resources. ### Infrastructure & Power Define robust clock, reset, and power management schemes capable of operating under automotive thermal profiles and supporting rapid "Instant-On" boot requirements ## Qualifications ### Education Bachelor’s or Master’s in Electrical Engineering or Computer Engineering (PhD desirable) ### Experience 12+ years in high-speed networking or SoC architecture, with at least 5 years focused on Automotive-grade silicon. ### TSN Mastery Deep expertise in IEEE 802.1 TSN protocols and their hardware implementation for real-time traffic shaping and synchronization. ### Protocol Expertise Expert knowledge of PCIe (Root Complex/Endpoint) and Automotive Ethernet (10BASE-T1S to 10G+ levels). ### Automotive Standards Familiarity with ISO 26262 functional safety flows and AEC-Q100 reliability requirements. ### System Integration Proven track record of integrating routing engines into complex SoCs using AXI/CHI bus protocols and managing IOMMU configurations. ## At a glance - Posted by the employer: Sep 21, 2026 - First seen by OpenNash: Oct 12, 2026 - Last checked: Oct 12, 2026 - Listed for: 21 days - Location: Austin, TEXAS, United States - Employment type: Full-time[Apply on Renesas Electronics’s careers site →](https://jobs.smartrecruiters.com/RenesasElectronics/744000150685139-principal-engineer-router-architect) ## More jobs at Renesas Electronics ### [AI Search & SEO Specialist](https://jobs.opennash.com/companies/renesas-electronics/jobs/29ef541e65bd041720a7/) Austin, TEXAS, United States ### [Application Engineer](https://jobs.opennash.com/companies/renesas-electronics/jobs/23a820dc0e636d90d082/) Austin, TEXAS, United States ### [Application Technology Architect – Drone & UAV Applications](https://jobs.opennash.com/companies/renesas-electronics/jobs/da0dd5ee2d8eb89c7af7/) Austin, TEXAS, United States ### [Electrical Engineer](https://jobs.opennash.com/companies/renesas-electronics/jobs/2947093f6d23a1dc6ebc/) Austin, TEXAS, United States ### [Principal Engineer, Automated Derivatives](https://jobs.opennash.com/companies/renesas-electronics/jobs/8adde7cab0395b53b0bc/) Austin, TEXAS, United States ## Similar jobs at other companies ### [Principal Software Engineer/ Architect](https://jobs.opennash.com/companies/microsoft/jobs/ab64246d02fb3d49338c/) Microsoft · United States, Washington, Redmond ### [Principal Software Engineer Architect](https://jobs.opennash.com/companies/microsoft/jobs/d096e6a8b78eb3e7411c/) Microsoft · United States, Washington, Redmond, Texas, Austin ### [AI/ML Platform Architect - Engineer, Principal](https://jobs.opennash.com/companies/qualcomm/jobs/af9b3b2819eaed7bb5b3/) Qualcomm · San Diego, California, United States of America ### [Principal Mission Architect Engineer/Senior Principal Mission Architect Engineer](https://jobs.opennash.com/companies/northrop-grumman/jobs/45a5ae5bcedc8d31e8d7/) Northrop Grumman · United States-Colorado-Colorado Springs ### [Principal Avionics Project Engineer - Router (ONSITE)](https://jobs.opennash.com/companies/rtx/jobs/4da85170d68afd50f125/) RTX OpenNash lists jobs from employers’ own careers sites and does not handle applications.
