Network DevOps Engineer, RDMA Fabric Automation

Vultr is seeking a highly skilled and experienced NetDevOps Engineer to help us evolve, automate and operate our RoCE-based Ethernet fabrics. This is a highly visible role in a high-growth technology company where you’l bel working at the intersection of network engineering, operations, automation, and observability. Building and operating the tooling and telemetry pipelines that keep the network fabrics fast, deterministic, and reliable at global scale. This is your opportunity to join our fast growing team that moves quickly, thinks programmatically and treats networks as software systems

Key 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.

Qualifications

• 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.
