Principal Engineer, Software Defined Networking

What you'll be doing:

  • Design and develop next-generation multi-tenant cloud SDN control and data plane software (OVS, OVN, OpenFlow)
  • Build Infrastructure-as-a-Service virtual network orchestration and services using gRPC and REST to support tenant workload security and performance SLAs for BMaaS, VMaaS, and Kubernetes
  • Drive upstream contributions to OVN-Kubernetes and related open-source projects
  • Develop software for network observability — monitoring, telemetry, intelligent metering, and performance analysis
  • Operate and support OVS-OVN based SDN solutions in large-scale NVIDIA AI Cloud environments
  • Own end-to-end observability for the SDN stack — build and maintain monitoring, alerting, distributed tracing, and dashboarding to ensure real-time insight into network health, performance, and tenant SLAs
  • Design, enhance, and maintain CI/CD pipelines (GitLab) across Linux host networking, OVS, OVN, and Kubernetes CNIs
  • Implement GitOps approaches or related experience for secure, seamless integration with cloud infrastructure
  • Collaborate with SRE, DevOps, and network engineering teams on production readiness and operational tooling

Requirements:

  • BS/MS in Computer Science or related technical field, or a comparable blend of education and relevant experience
  • 15+ years of proven experience in software development for large-scale distributed environments
  • Expert-level knowledge of OVN, OVS, OpenFlow, and modern network protocols
  • Strong programming skills in C and Go; advanced scripting in Bash and Python
  • Deep knowledge of Kubernetes, practical experience deploying and supporting CNIs (OVN-Kubernetes)
  • Hands-on experience with Infrastructure-as-Code and deployment tools (Ansible, Terraform, ArgoCD, Flux)
  • Experience designing and operating complex, multi-stage CI/CD pipelines
  • Hands-on experience developing secure, high-performance services using gRPC and REST with TLS and strong authentication
  • Strong knowledge of datacenter routing, switching, and Linux host/VM networking

Nice to haves:

  • Contributions to open-source projects (especially OVS, OVN, OVN-Kubernetes, or other Kubernetes networking projects)
  • Experience with hardware acceleration (GPU, DPU or equivalent experience) for networking
  • Practical experience with major cloud providers (AWS, Azure, GCP) and hybrid/multi-cloud deployments
  • SRE/DevOps top-level expertise — on-call, incident management, operations focused on service reliability targets, production ownership
  • Experience with observability platforms and tools (Prometheus, Grafana, Jaeger, OpenTelemetry, ELK)
