About the Role
About the role Our client is looking for an experienced software engineer to work at the lower layers of our networking stack. You’ll design, build, and debug kernel-level and user-space code that moves traffic at carrier scale, owning performance-critical data paths from the socket layer down to the driver. This is a deep-systems role for someone who is genuinely comfortable inside the kernel and the DPDK networking stack. What you’ll do • Design and implement Linux kernel modules and kernel-space networking components in C. • Build and optimize high-throughput packet processing using DPDK — a core part of this role. • Develop and tune TCP and UDP optimization algorithms for throughput, latency, and reliability under production load at scale. Those algorithms are being used by Millions of users worldwide. • Diagnose and resolve low-level faults - kernel panics, race condition, deadlocks, memory corruption, and performance regressions - using crash/kdump, gdb, ftrace, kprobes, and perf. • Profile and tune system performance across the full network stack. • Collaborate with product and infrastructure teams to bring features from design through production hardening. • Contribute to code reviews, technical design docs, and long-term architectural decisions. What you bring • 5+ years of Linux Kernel or DPDK software engineering experience. • Strong Linux kernel development background — modules, drivers, and kernel internals. • Expert-level C programming skills. • Hands-on DPDK development experience. • Deep working knowledge of the TCP/IP protocol suite • Proven experience debugging low-level failures with crash dumps and kernel tools (kdump, gdb, crash util, perf). • Comfort with Linux at the command line and version control. Nice to have • Working knowledge of 5G architecture (core network, RAN concepts, user-plane/control- plane separation). • Experience with carrier-grade or high-throughput networking systems. • Experience with RedHat Kernel ecosystem version 8.5 and higher. Location Fully remote.
