Principal Engineer, Router Architecture

About the Role We are seeking a Principal Router Architect with 10 to 15 years of experience to define the backbone of next-generation zonal and central compute automotive architectures. 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, including IEEE 802.1AS, 802.1Qbv, and 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. • Functional Safety (ASIL): Integrate hardware safety mechanisms such as ECC, parity, BIST, and end-to-end protection to meet ASIL-B/D requirements within routing engines 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, including camera and LiDAR, as well as 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 • Bachelor’s or Master’s degree in Electrical Engineering or Computer Engineering. PhD is desirable. • 12+ years of experience in high-speed networking or SoC architecture, with at least 5 years focused on automotive-grade silicon. • Deep expertise in IEEE 802.1 TSN protocols and their hardware implementation for real-time traffic shaping and synchronization. • Expert knowledge of PCIe Root Complex/Endpoint architecture and Automotive Ethernet, from 10BASE-T1S to 10G+ levels. • Familiarity with ISO 26262 functional safety flows and AEC-Q100 reliability requirements. • Proven track record integrating routing engines into complex SoCs using AXI/CHI bus protocols and managing IOMMU configurations.
