Requirements
• Solid understanding of modern data center networking: EVPN-VXLAN, BGP, MLAG, QoS, and traffic engineering. • Deep familiarity with RoCEv2, RDMA transport tuning, ECN/PFC, and lossless Ethernet design. • Strong experience with automation frameworks like Ansible, and languages like Python, Golang, Rust, or PHP • Comfort working with telemetry and monitoring stacks — Prometheus, Grafana, Loki, ELK, or similar. • Previous experience integrating with NetBox, Nautobot, OpsMill or similar for topology and configuration source-of-truth. • Familiarity with CI/CD systems (GitHub Actions, Jenkins, ArgoCD) for continuous delivery of network automation. • Strong Linux networking background, including namespaces, netlink, and system-level debugging.
Responsibilities
• Automate deployment and operations of large-scale RDMA (RoCEv2) Ethernet fabrics across Vultr data centers. • Build Ansible and Python-based frameworks to provision, validate, and remediate underlay and overlay networks. • Integrate network automation with Vultr’s source-of-truth systems (NetBox, OpsMill) for intent-driven configuration and validation. • Develop telemetry ingestion and correlation pipelines (gNMI, Prometheus, Kafka, custom collectors) for real-time network health and performance metrics. • Collaborate with platform, orchestration, and product engineering teams to optimize RDMA performance, PFC/ECN behavior, and path symmetry across fabrics. • Implement CI/CD workflows for network configuration changes — validation, pre-checks, and rollbacks. • Investigate complex network behaviors across layers — flow hashing, congestion domains, ECMP, and overlay interactions. • Contribute to the design of next-generation GPU and AI interconnect fabrics, ensuring seamless integration into Vultr’s global network architecture.
Benefits
• $90,000 - $130,000 • Final compensation will vary depending on years of experience, background/skill set, location, and applicable laws. • Inclusion & Privacy
