What You Will Do

HPC Infrastructure Operations

• Support and maintain Linux-based HPC and AI computing environments, including large-scale NVIDIA GPU clusters, while troubleshooting hardware, operating system, networking, storage, driver, and firmware issues across bare-metal, virtualized, containerized, and cloud-hosted platforms.
• Investigate and resolve infrastructure and compute-node issues, document technical findings, maintain operational runbooks and support procedures, and collaborate with senior engineers to **escalate** complex problems and improve overall system reliability.

GPU and Accelerated Computing Systems

• Assist with the installation, configuration, validation, monitoring, and troubleshooting of NVIDIA GPU infrastructure, including drivers, firmware, system software, and GPU health management tools, while diagnosing performance, communication, and hardware-related issues.
• Perform post-maintenance system validation, collect and analyze diagnostic data for GPU and infrastructure faults, and coordinate hardware replacement and RMA activities for GPUs, system boards, NICs, power supplies, and other server components.

Linux System Administration

• Administer and support enterprise Linux environments, including system services, filesystems, networking, storage, authentication, permissions, SSH, DNS, and NTP, while ensuring compliance with established security and operating system standards.
• Troubleshoot operating system, CPU, memory, device-discovery, and kernel-related issues, and collect diagnostic data to investigate system crashes, hardware failures, and performance-related incidents.

Server Hardware, Firmware, and Out-of-Band Management

• Troubleshoot hardware issues across enterprise server platforms, including memory, PCIe devices, GPUs, NICs, storage systems, power supplies, fans, system boards, and cabling, while supporting firmware updates for BIOS, BMC, GPUs, drives, and other infrastructure components.
• Utilize out-of-band management tools to perform remote administration, system health monitoring, hardware inventory and log collection, and collaborate with Data Center technicians on hardware replacements, break-fix activities, cabling validation, and post-maintenance testing.

High-Performance Networking

• Assist with troubleshooting Ethernet, InfiniBand, and RoCE connectivity within HPC and AI environments, including support for NVIDIA/Mellanox network adapters and resolution of link, interface, MTU, packet loss, VLAN, RDMA, and fabric-related issues.
• Collect and analyze network diagnostic data, elevate complex switching and fabric issues to Network Engineering teams, and validate network performance following infrastructure changes, firmware upgrades, cable replacements, and new system deployments.

Incident, Problem, and Change Management

• Participate in incident response activities for production infrastructure environments, troubleshoot technical issues, provide status updates, and elevate incidents in accordance with established support procedures and service-level agreements.
• Document troubleshooting activities, findings, corrective actions, and resolutions while following change-management processes, maintenance procedures, rollback plans, and on-call support requirements.

Collaboration and Development

• Collaborate with senior Systems Administrators and engineers to troubleshoot HPC infrastructure issues, follow established operational procedures, and participate in technical reviews, troubleshooting sessions, and post-incident analyses.
• Contribute to runbooks, knowledge-base articles, and support documentation, share technical findings and lessons learned, and continuously develop expertise in Linux, GPU infrastructure, high-performance networking, storage, and automation technologies.

What You Bring

• Approximately 5 years of experience in Linux systems administration, data center operations, infrastructure support, HPC, cloud infrastructure, or a related technical role. Equivalent hands-on experience, education, or technical training may also be considered.
• Working knowledge of Linux operating systems and command-line administration.
• Basic understanding of enterprise server hardware and common server components.
• Experience troubleshooting hardware or operating-system issues using logs and diagnostic tools.
• Familiarity with networking fundamentals including IP addressing, DNS, interfaces, routing, and basic connectivity troubleshooting.
• Familiarity with server hardware concepts including CPU, memory, storage, PCIe devices, NICs, power supplies, and firmware.
• Exposure to GPU infrastructure or an interest in developing expertise with NVIDIA accelerated computing platforms.
• Familiarity with out-of-band management technologies such as IPMI, Redfish, iDRAC, iLO, or equivalent tools.
• Basic scripting or automation experience using Bash, Python, PowerShell, Ansible, or similar technologies.
• Ability to follow technical procedures and troubleshoot problems methodically.
• Ability to recognize when an issue requires escalation and clearly communicate collected findings.
• Strong written communication and documentation skills.
• Ability to work collaboratively across technical teams.
• Participate in an on-call rotation.
