Principal Engineer, Router Architect

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 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.
