# Deep Tech Networking Engineer, DPDK / Linux - Paris - H/F

At Free/Iliad, we build embedded networking products including 5G and edge gateways, OLTs, carrier-grade routers and NPU-based appliances. Our systems forward tens to hundreds of Gbps on Arm64 SoCs, x86, ASICs and DPUs, within strict power and hardware constraints. The dataplane runs on DPDK or dedicated hardware, while Linux remains the control plane. Performance is not theoretical. We measure Mpps, p99 latency, jitter and watts per Gbps on real hardware deployed at scale. Open source is also central to how we work. Rather than maintaining private patches through every rebase, we contribute improvements to DPDK, Linux, U-Boot and Buildroot. Depending on the project and your experience, upstream work may represent between 20% and 80% of your time. It is planned and tracked like any other deliverable. We are looking for engineers who want to make packets go faster, understand why they go faster and prove it with numbers. Your role : You will design, develop and optimise high-performance networking systems from the hardware to the dataplane. Your responsibilities will include: Building packet-processing pipelines with DPDK, including PMDs, mempools, mbufs, rings, lcores, eventdev, g
