Software Engineer at Meta
Gothenburg, Sweden
Summary
👤
Senior🎓
Top SchoolBjörn Töpel is a seasoned software engineer with 13 years of deep systems experience focused on Linux kernel internals, high-performance networking, and low-level toolchains. A long-time kernel maintainer (AF_XDP and the RISC‑V eBPF JIT) and Individual RISC‑V member, he blends production-grade driver and networking work with compiler/linker and performance tuning expertise. He’s shipped firmware and system-transparency work at Mullvad, led kernel networking efforts at Intel and Rivos, and now continues at Meta, demonstrating an unusual mix of applied research and production engineering. Equally comfortable in C/C++ and Rust, he pairs concurrent/parallel systems knowledge with an Emacs-centric workflow and a soft spot for FOSS and librarian-like order. Colleagues know him for turning kernel-level tinkering into measurable packet‑path and latency wins while advocating open platforms and RISC‑V progress.
