SeniorSoftwareEngineer,HBN

NVIDIA is seeking a Senior Software Engineer to join the Host-Based Networking (HBN) team. HBN is a high-impact product within the DOCA ecosystem, providing the networking foundation for the AI Factory and massive-scale GPU clusters. By offloading the networking stack to the NVIDIA BlueField DPU, our service enables hardware-accelerated, tenant-aware connectivity for the world’s most advanced AI infrastructure. We are looking for a versatile engineer who is ready to lead technical initiatives and drive the development of networking systems that power the next generation of AI. If you are a quick learner with a passion for high-performance networking and complex system-level challenges, we want to hear from you. **What you’ll be doing:** * Design DPU-Resident Services: Design and implement networking features for our containerized service running directly on the BlueField DPU platform. * Optimize System Performance: Develop and maintain the forwarding daemon, bridging Linux networking states with hardware acceleration for wire-speed performance. * Forwarding & Protocol Integration: Implement hardware-accelerated forwarding (e.g., VXLAN) and integrate with L3 control planes (BGP, EVPN) to support multi-tenant isolation. * System-Level Debugging: Analyze and resolve complex interactions between the HBN container, the DPU kernel, and low-level networking drivers. * Shaping Technical Direction: Partner with architecture teams to design and integrate next-generation networking features for production-ready hardware within the DOCA ecosystem. * Lead Technical Initiatives: Drive the software lifecycle of key components, from initial design through to large-scale deployment and production support. **What we need to see:** * B.Sc. in Computer Science, Computer Engineering, or Electrical Engineering (or equivalent experience). * 5+ years of experience in enterprise software development with a focus on C and Python. * Deep familiarity with Linux internals and the kernel network
