[Hiring] NIC Kernel Driver Managing Engineer @Cornelis Networks, Inc.

Role Description

We are seeking a Managing Engineer to lead the team responsible for Cornelis Networks' NIC Linux kernel drivers. We seek a technical manager; responsibilities are split between leading, planning, and growing a team of up to 6 kernel engineers, and reviewing patches, debugging, and contributing code. Our drivers are developed upstream-first and maintained in-tree with Linux, so you will drive both product delivery and community engagement across the kernel, RDMA, and netdev subsystems. You will own the Linux kernel drivers for three generations of our own silicon:

• CN5000 at 400 Gbps
• CN6000 at 800 Gbps on PCIe Gen6, bringing a hardware-accelerated RoCEv2 datapath and standard netdev support alongside Omni-Path
• CN7000 at 1.6 Tbps with Ultra Ethernet

Qualifications

• 8+ years of systems/kernel software engineering experience in C on Linux
• Bachelor's degree in Computer Science, Computer Engineering, or related field (or equivalent experience); Master's or Doctorate a plus

• Hands-on Linux device driver development experience
• Depth in at least one high-performance networking subsystem
• Demonstrated ability to diagnose performance and correctness issues in low-latency, high-throughput data paths
• Experience contributing to open-source projects, with familiarity with upstream Linux patch and review processes
• Strong written and verbal communication skills

Requirements

• Perform code and design reviews, contribute patches, and lead debug of complex kernel issues (PCIe/MMIO, DMA, MSI-X and interrupt handling, memory registration and address translation, command/completion ring management, device reset and error recovery)
• Drive driver enablement ahead of tapeout using emulation, FPGA prototypes, and virtual PCIe device models
• Drive patch submission and review cycles on linux-rdma, netdev, and related mailing lists
• Partner with ASIC/silicon, firmware, libfabric provider, middleware, and validation teams
• Establish and maintain CI, regression, and stress coverage for driver changes
• Triage escalations, reproduce customer-reported issues, and translate findings into prioritized fixes

Benefits

• Competitive compensation package that includes equity, cash, and incentives
