Senior System Software Engineer, Software Defined Networking

Jobtailor; Deutschland; Remote; EUR 90.000 - 140.000; Vollzeit

Zusammenfassung

Jobtailor is seeking an experienced SDN software engineer to design and implement multi-tenant cloud networking using OVS/OVN/OpenFlow. You will build IaaS network orchestration with gRPC/REST for BMaaS, VMaaS, and Kubernetes, contribute to open-source projects, and strengthen observability and CI/CD pipelines.

The role requires deep networking knowledge, strong C/Go programming, and hands-on experience with IaC tools, cloud providers, and distributed systems.

Qualifikationen

• BS/MS in Computer Science or related field, or equivalent experience.
• 5+ years of software development in large-scale distributed environments.
• Expert-level knowledge of OVN, OVS, OpenFlow, and modern network protocols.
• Strong programming skills in C and Go; scripting in Bash and Python.
• Deep knowledge of Kubernetes and OVN-Kubernetes.
• Hands-on experience with IaC and deployment tools (Ansible, Terraform, ArgoCD, Flux).
• Experience designing and operating multi-stage CI/CD pipelines.
• 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.
• Contributions to open-source projects, especially OVS, OVN, OVN-Kubernetes, or other Kubernetes networking projects.
• Experience with hardware acceleration for networking.
• Experience with major cloud providers (AWS, Azure, GCP) and hybrid/multi-cloud deployments.
• SRE/DevOps expertise, including on-call, incident management, operations focused on service reliability targets, and production ownership.
• Experience with observability platforms and tools (Prometheus, Grafana, Jaeger, OpenTelemetry, ELK)

Aufgaben

• Design and develop next-generation multi-tenant cloud SDN control and data plane software using OVS, OVN, and OpenFlow
• Build Infrastructure-as-Service virtual network orchestration and services using gRPC and REST for BMaaS, VMaaS, and Kubernetes
• Drive upstream contributions to OVN-Kubernetes and related open-source projects
• Develop software for network observability, including monitoring, telemetry, intelligent metering, and performance analysis
• Operate and support OVS-OVN based SDN solutions in large-scale NVIDIA AI Cloud environments
• Build and maintain monitoring, alerting, distributed tracing, and dashboarding for the SDN stack
• Design, enhance, and maintain GitLab CI/CD pipelines across Linux host networking, OVS, OVN, and Kubernetes CNIs
• Implement GitOps approaches and integrate securely with cloud infrastructure
• Drive reliability through incident management, resource monitoring, and performance tuning
• Collaborate with SRE, DevOps, and network engineering teams on production readiness and operational tooling
