Go and Kubernetes experience are helpful but not required; strong engineering fundamentals and network automation experience matter more., * Deep hands-on experience with Ethernet switching, IP routing, BGP-based leaf-spine fabrics, EVPN/VXLAN, and VRF-based multitenancy. * Strong judgment around fabric underlay and overlay design, scale, convergence, isolation, and failure modes. * Experience building or operating production network automation, including desired state, idempotency, concurrency, observability, and recovery. * Strong software-engineering fundamentals in a general-purpose language. You can design, test, debug, and review production systems and are willing to become productive in Go. * Experience with southbound network APIs and structured configuration, such as REST, gNMI/OpenConfig, or NETCONF. * Hands-on experience with major data-center network operating systems, such as Cumulus Linux, Arista EOS, SONiC, Junos, or NX-OS. * Strong diagnostic skills using routing and EVPN state, packet captures, counters, telemetry, and logs. * Clear, pragmatic communication and a collaborative approach to technical leadership. Nice to Have * Experience reading, reviewing, or contributing to Go code. * Familiarity with Kubernetes controllers, operators, CRDs, reconciliation, or Kubebuilder. * Experience with physical or simulated network labs such as containerlab, NVIDIA Air, EVE-NG, GNS3, or similar environments. * Experience with high-performance Ethernet, RoCE, InfiniBand, HPC, or large-scale GPU infrastructure. ## Description As a Software Engineer, Network Automation - Data Center Fabrics, you will help design and build systems for operating large-scale networks within our data centers. You will apply deep networking expertise to leaf-spine architecture, automation, testing, and production troubleshooting across Ethernet switching, IP routing, BGP, EVPN/VXLAN, and VRFs., * Design and evolve leaf-spine underlays, EVPN/VXLAN overlays, and tenant connectivity for multi-tenant AI infrastructure. * Translate data-center fabric requirements and safety properties into clear APIs, data models, validation, and automation. * Build reliable control-plane software that reconciles desired and observed network state. * Design safe change workflows with validation, dry runs, atomic updates, observability, and failure recovery. * Integrate with data-center switch operating systems and management APIs while maintaining vendor-neutral abstractions where practical. * Participate in the on-call rotation, troubleshoot active data-center network incidents, restore service, and turn root causes into lasting improvements. * Review designs and code, explain networking trade-offs, and help raise network engineering quality across the organization. * Develop lab and production tests and turn operational lessons into better software and architecture. ## Related Videos - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [From Factory Floor to Kubernetes Core: Building an Edge Platform One Step at a Time](https://www.wearedevelopers.com/videos/1415-from-factory-floor-to-kubernetes-core-building-an-edge-platform-one-step-at-a-time) - [The Gashlycrumb Tinies of AI Networking You Must Know (or Languish!)](https://www.wearedevelopers.com/videos/2067-the-gashlycrumb-tinies-of-ai-networking-you-must-know-or-languish) - [Discover the open source trio you didn’t expect: .NET and PostgreSQL on Linux](https://www.wearedevelopers.com/videos/2042-discover-the-open-source-trio-you-didn-t-expect-net-and-postgresql-on-linux) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
