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 (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
