Principal Software Engineer - Linux Networking at NVIDIA
Czechia
Summary
👤
Senior🎓
Top SchoolJiří Pírko is a Principal Software Engineer with 13 years of deep Linux networking and kernel development experience, now leading Linux networking work at NVIDIA. He maintains multiple kernel subsystems including team, devlink, switchdev and TC, and shepherds related userspace libraries like libteam and libndp, blending system architecture with hands‑on driver implementation. His open source footprint includes contributions to high-impact projects such as iproute2, NetworkManager and the kernel fuzzer syzkaller, where he has extended syscall support and fixed security issues. Known for pragmatic upstream-first engineering, he routinely implements device features (e.g., queue management, bonding/team support) and integrates complex userspace/kernel interactions. Colocated in Czechia, he pairs a strong academic background in informatics with long-term experience across Red Hat, Mellanox and NVIDIA, and often serves as a free-software advocate and consultant.
