Truminds - Ethernet Driver Developer

Job Description

Job Description Ethernet Driver developer is responsible for ensuring Ethernet driver development / maintenance and feature migration over varying SoCs targeted towards different domains (Automotive / Home Router / IOT etc) Key Responsibilities Develop, Customize and optimize Ethernet Drivers for specific chipsets, board variants. Kernel Integration : Interface the driver with the Linux network stack, including the NAPI (New API) subsystem, netdev, and sk_buff management for efficient packet processing Performance Tuning : Optimize Ethernet driver performance for high throughput, low latency, and minimal CPU utilization. Ensure high scalability and efficient packet handling. Debugging & Troubleshooting : Investigate, resolve complex network issues related to Ethernet drivers - latency problems, connectivity issues, and performance degradation. System Integration : Work closely with HW engineers, firmware developers, kernel team to ensure tight integration between the Ethernet driver and the underlying network stack. Leverage tools like Wireshark, tcpdump, and kernel logs for analysis. Platform Support : Develop drivers that support multiple platforms, including x86, ARM, and other custom SoCs (System on Chips) Educational Qualifications : Bachelors or Masters in Electronics, Electrical, or Computer Engineering. Experience 5- 10 years in Linux Device driver / Kernel development. Design, implement, and optimize Ethernet drivers for various HW platforms (NICs, switches, and embedded systems Expertise with NICs and platform-specific hardware, including PCIe and DMA, , and Interrupts (MSI/MSI-X) Debugging : Kernel debugging tools (e., GDB, kdb, WinDbg) and network analysis tools. Solid skills in C, Shell scripting, and Compilation environment Good knowledge of Linux Layer 2 / 3 Networking protocols Nice-to-Have Skills Knowledge of Virtualization features such as SR-IOV (Single Root I/O Virtualization), VFIO and network function virtualization (NFV). Familiarity with advanced Ethernet technologies like RDMA (Remote Direct Memory Access), RoCE (RDMA over Converged Ethernet), or DPDK (Data Plane Development Kit) Contributions to open-source kernel projects (ref:hirist.tech)
