Remote Network DevOps Engineer, RDMA Fabric Automation

Description:

• Vultr is seeking a highly skilled and experienced NetDevOps Engineer to help evolve, automate, and operate RoCE-based Ethernet fabrics.
• This role is highly visible in a high-growth technology company, working at the intersection of network engineering, operations, automation, and observability.
• The engineer will build and operate tooling and telemetry pipelines to maintain fast, deterministic, and reliable network fabrics at a global scale.
• Key responsibilities include automating deployment and operations of large-scale RDMA (RoCEv2) Ethernet fabrics across Vultr data centers.
• The engineer will build Ansible and Python-based frameworks for provisioning, validating, and remediating underlay and overlay networks.
• Integration of network automation with Vultr’s source-of-truth systems (NetBox, OpsMill) for intent-driven configuration and validation is required.
• Development of telemetry ingestion and correlation pipelines (gNMI, Prometheus, Kafka, custom collectors) for real-time network health and performance metrics is essential.
• Collaboration with platform, orchestration, and product engineering teams to optimize RDMA performance, PFC/ECN behavior, and path symmetry across fabrics is expected.
• Implementation of CI/CD workflows for network configuration changes, including validation, pre-checks, and rollbacks, is part of the role.
• The engineer will investigate complex network behaviors across layers, including flow hashing, congestion domains, ECMP, and overlay interactions.
• Contribution to the design of next-generation GPU and AI interconnect fabrics, ensuring seamless integration into Vultr’s global network architecture, is also required.

Requirements:

• A solid understanding of modern data center networking, including EVPN-VXLAN, BGP, MLAG, QoS, and traffic engineering, is necessary.
• Deep familiarity with RoCEv2, RDMA transport tuning, ECN/PFC, and lossless Ethernet design is required.
• Strong experience with automation frameworks like Ansible and programming languages such as Python, Golang, Rust, or PHP is essential.
• Comfort working with telemetry and monitoring stacks, including Prometheus, Grafana, Loki, ELK, or similar, is expected.
• Previous experience integrating with NetBox, Nautobot, OpsMill, or similar for topology and configuration source-of-truth is required.
• Familiarity with CI/CD systems (GitHub Actions, Jenkins, ArgoCD) for continuous delivery of network automation is necessary.
• A strong Linux networking background, including knowledge of namespaces, netlink, and system-level debugging, is essential.

Benefits:

• Vultr offers 100% company-paid insurance premiums for employee medical, dental, and vision plans.
• A 401(k) plan that matches 100% up to 4%, with immediate vesting, is provided.
• Professional Development Reimbursement of $2,500 each year is available for employees.
• Employees receive 11 Holidays, Paid Time Off Accrual, and a Rollover Plan.
• Increased PTO is offered at 3-year and 10-year anniversaries, along with a 1-month paid sabbatical every 5 years and an Anniversary Bonus each year.
• A $500 stipend for remote office setup in the first year and $400 each following year is provided.
• Internet reimbursement up to $75 per month is available.
• Gym membership reimbursement up to $50 per month is offered.
• A company-paid Wellable subscription is included as part of the benefits package.
