Job description

Responsibilities:

• Automotive Ethernet Routing: Architect L2/L3 switch fabrics supportingTime-Sensitive Networking (TSN) standards (e.g., IEEE 802.1AS, 802.1Qbv, 802.1Qbu) to ensure deterministic latency for safety-critical traffic.
• PCIe Backbone Architecture: DefinePCIe Gen 5/6 integration for high-speed chip-to-chip connectivity between SoCs, AI accelerators, and storage, including support forSR-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 meetASIL-B/Drequirements within the routing engine and bus fabrics.
• Zonal Interconnect & Bus Fabric: Design the interface between Ethernet/PCIe controllers and internalNoC/CHI fabrics, ensuring efficient data movement for ADAS sensors (Camera, LiDAR) and telemetry.
• Virtualization & Security: Architect hardware-assisted isolation andSecure On-board Communication (SecOC) to protect the vehicle network from cyber threats while allowing shared access to network resources.
• Infrastructure & Power: Define robustclock, 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 onAutomotive-grade silicon.
• TSN Mastery: Deep expertise inIEEE 802.1 TSN protocols and their hardware implementation for real-time traffic shaping and synchronization.
• Protocol Expertise: Expert knowledge ofPCIe (Root Complex/Endpoint) andAutomotive Ethernet (10BASE-T1S to 10G+ levels).
• Automotive Standards: Familiarity withISO 26262 functional safety flows andAEC-Q100 reliability requirements.
• System Integration: Proven track record of integrating routing engines into complex SoCs usingAXI/CHI bus protocols and managing IOMMU configurations.
