Network DevOps Engineer, RDMA Fabric Automation

Role Overview

As a Network DevOps Engineer (RDMA Fabric Automation) at Vultr, you’ll help evolve, automate, and operate RoCE-based Ethernet fabrics. This role sits at the intersection of network engineering, operations, automation, and observability, where you’ll build the tooling and telemetry pipelines that keep fabrics fast, deterministic, and reliable at global scale.

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 automation with Vultr source-of-truth systems (e.g., NetBox, OpsMill) for intent-driven configuration and validation.
• Develop telemetry ingestion/correlation pipelines for real-time network health and performance metrics (e.g., gNMI, Prometheus, Kafka, custom collectors).
• Collaborate with platform/orchestration/product engineering teams to optimize:
  • RDMA performance
  • PFC/ECN behavior
  • Path symmetry across fabrics
• Implement CI/CD workflows for network configuration changes, including validation, pre-checks, and rollbacks.
• Investigate complex networking behavior across layers (e.g., flow hashing, congestion domains, ECMP, overlay interactions).
• Contribute to design of next-generation GPU/AI interconnect fabrics integrated into Vultr’s global network architecture.

Requirements

• Strong understanding of modern data center networking: EVPN-VXLAN, BGP, MLAG, QoS, traffic engineering.
• Deep familiarity with RoCEv2/RDMA transport tuning, ECN/PFC, and lossless Ethernet design.
• Proven automation experience with Ansible, and programming in Python (plus experience with Golang, Rust, or PHP).
• Experience with telemetry/monitoring stacks such as Prometheus, Grafana, Loki, ELK.
• Experience integrating with network source-of-truth tools such as NetBox, Nautobot, OpsMill.
• CI/CD familiarity with GitHub Actions, Jenkins, ArgoCD.
• Strong Linux networking background (e.g., namespaces, netlink, system-level debugging).

Compensation

• $90,000 - $130,000 (varies by location, years of experience, background, and skills).
