Senior Software Engineer, 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.
  
  

• 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 networking stack, including Netlink, routing, and bridging.
• Expertise in Layer-3 protocol integration (BGP, EVPN) and network overlay technologies (VXLAN).
• A self-motivated technical leader capable of driving projects and mentoring others in an agile, high-velocity environment.
  
  

• Switching & Acceleration: Experience with OVS (Open vSwitch), OpenFlow, eSwitch, or DPDK.
• Container Orchestration: Proficiency with Kubernetes (K8s), container orchestration platforms, and working within containerized environments.
• Linux Kernel Expertise: Hands-on experience with the ARM/Linux kernel stack and Linux networking drivers.
