The Role

Your Role

As an RoCE / Infiniband Network Engineer, you will provide hands-on troubleshooting and change execution for high-speed Graphics Processing Unit (GPU) fabrics. You will work with Remote Direct Memory Access over Converged Ethernet (RoCE) and/or InfiniBand environments, restoring service for common link, switch, Host Channel Adapter (HCA), Network Interface Card (NIC), Remote Direct Memory Access (RDMA), congestion and configuration issues. You will own service restoration and elevate architectural or highly complex fabric conditions to the appropriate Subject Matter Expert (SME).

What You Will Do

• Troubleshoot switch, HCA/NIC, port and optic issues using the Command-Line Interface (CLI), telemetry and fabric-management tools.
• Analyze link errors, drops, flaps, speed and Forward Error Correction (FEC) conditions, congestion counters and RDMA reachability.
• Operate InfiniBand/Unified Fabric Manager (UFM) or NVIDIA Spectrum-X/RoCE management tooling within approved access boundaries.
• For RoCE environments, troubleshoot Data Center Bridging (DCB), Priority Flow Control (PFC), Explicit Congestion Notification (ECN), Quality of Service (QoS) configuration and common lossless-network issues.
• For InfiniBand environments, troubleshoot link, subnet and fabric conditions, HCA state and common subnet-management issues.
• Participate in Border Gateway Protocol (BGP), Ethernet Virtual Private Network (EVPN), leaf-spine and fabric change implementation as defined by site architecture.
• Correlate network and fabric symptoms with multi-node GPU/NVIDIA Collective Communications Library (NCCL) workload degradation and engage compute/software teams as needed.
• Perform approved firmware and Operating System (OS) changes, cable/optic replacement and post-change validation.
• Own Service-Level Agreement (SLA) and ticket progression, contribute to Root Cause Analysis (RCA), mentor Level 1 (L1) engineers and improve operational runbooks.

Your Future at Kyndryl

This role gives you the opportunity to deepen your expertise in high-speed networking for GPU, AI and High-Performance Computing (HPC) environments while expanding your capabilities across RDMA, RoCE, InfiniBand, fabric telemetry and automation. As your experience grows, you can progress toward senior network engineering, fabric specialist, architecture or technical leadership roles, supported by continuous learning and hands-on experience in mission-critical environments.

However, equally as important, you have a growth mindset and are keen to drive your own personal and professional development. You are customer-focused, someone who prioritizes customer success in their work. And finally, you're open and borderless, naturally inclusive in how you work with others.

Required Skills and Experience

• 3-5+ years of data-center network engineering experience, including hands-on high-speed fabric experience.
• Production experience with RoCE version 2 (RoCEv2)/RDMA and/or InfiniBand; experience in GPU or HPC environments is strongly preferred.
• Hands-on experience with switch CLI, optics/cabling, NIC/HCA diagnostics and performance counters.
• Working knowledge of DCB, PFC, ECN, QoS and lossless Ethernet for RoCE environments.
• Working knowledge of UFM and subnet-management concepts for InfiniBand environments.
• Experience with leaf-spine, BGP/EVPN and high-speed 100/200/400 Gigabit (Gb)+ fabrics.
• Formal incident management, change management and RCA experience.
