Network DevOps Engineer, RDMA Fabric Automation - Multiple Openings

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.
