About The Position

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.

Requirements

Bachelor’s or Master’s in Electrical Engineering or Computer Engineering (PhD desirable)
12+ years 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) and Automotive Ethernet (10BASE-T1S to 10G+ levels).
Familiarity with ISO 26262 functional safety flows and AEC-Q100 reliability requirements.
Proven track record of integrating routing engines into complex SoCs using AXI/CHI bus protocols and managing IOMMU configurations.

Responsibilities

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.
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).
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.
Design the interface between Ethernet/PCIe controllers and internal NoC/CHI fabrics, ensuring efficient data movement for ADAS sensors (Camera, LiDAR) and telemetry.
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.
Define robust clock, reset, and power management schemes capable of operating under automotive thermal profiles and supporting rapid "Instant-On" boot requirements.
