Résumé du poste

Kalray is expanding its Software Networking team in Montbonnot or Sophia Antipolis, France. You will join a small, dynamic group crafting networking software for the DPU platform, from MAC/PHY drivers to data plane optimization.

The role targets embedded software engineers with 3+ years of experience, strong C, Linux kernel, Python, and networking know-how, plus familiarity with DPDK/OVS and virtualization tech.

Qualifications

• Strong proficiency in C programming and experience with large-scale software development.
• Solid experience with Linux kernel development, device drivers, or similar low-level programming.
• Proficiency in Python for scripting, automation, and test framework development.
• Good understanding of fundamental networking concepts, including TCP/IP, Ethernet, network protocols and packet forwarding techniques.
• Hands-on experience with the Data Plane Development Kit (DPDK) framework.
• Familiarity with Open vSwitch (OVS) architecture and hardware offload mechanisms.
• Experience with low-level hardware interfaces, such as MAC/PHY components.
• Knowledge of virtualization technologies like SR-IOV and KVM.
• Experience with performance tuning and optimization of networking data planes.

Responsabilités

• Design, develop, and optimize networking software for our cutting-edge DPU platform.
• Create and maintain low-level software, including MAC/PHY drivers and packet forwarding engine firmware.
• Develop and enhance Linux kernel drivers to support network offloads and hardware acceleration features.
• Implement and optimize data plane solutions utilizing the Data Plane Development Kit (DPDK) and Open vSwitch (OVS).
• Build and maintain robust, scalable, and automated test frameworks using Python to ensure software quality and performance.
