This position is based in Spain, and you will collaborate with teams across Europe and an international partnership landscape.
Design and implement high-performance packet I / O pipelines using DPDK or equivalent frameworks.
Adapt existing UDP application code to work with NIC queue–driven RX / TX loops, batch processing, and hardware offloads.
Configure and tune Linux servers for ultra-low latency : hugepages, NUMA awareness, CPU pinning, NIC driver binding, RSS / flow steering.
Ensure reliable operation at very high packet rates; instrument detailed throughput, latency, and packet-loss metrics.
Collaborate with the application team to integrate kernel-bypass transport with existing processing pipelines.
Stay current with RDMA and user-space networking trends (DPDK, netmap, AF_XDP, eBPF / XDP) to evaluate trade-offs.
Expert C / C++ in performance-critical networking code.
Hands‑on experience with DPDK or similar (AF_XDP, netmap, PF_RING) in production systems.
Strong knowledge of Linux performance tuning and NIC hardware features (RSS, flow steering, checksum / jumbo offloads).
Familiarity with RDMA (RoCE, InfiniBand, iWARP) concepts and when to use them vs. raw packet I / O.
Experience with packet capture / analysis tools (tcpdump, Wireshark, perf).
Strong problem‑solving and debugging skills at the network + OS boundary.
Excellent English communication skills – written and spoken.
Working with international clients.
An environment to develop your professional capabilities and take ownership.
Collaboration with a team of open, dynamic, and international experts.
Full‑time position with a competitive salary and benefits, including learning opportunities.
Flexible working hours.
Get‑together team events.
