Qualifications

• 3-6 years in datacenter operations, systems administration, hardware support, or infrastructure engineering.
• Hands-on experience with enterprise server hardware: component replacement, POST and boot failures, and reading hardware behavior at the rack.
• Practical experience with BMCs and out-of-band management: IPMI, Redfish, iDRAC, iLO, or equivalent.
• Strong Linux troubleshooting: boot process, driver and device issues, and diagnostic tools such as dmesg, lspci, ipmitool, and SMART.
• Comfort reading sensor data, event logs, and telemetry to identify failures.
• Working scripting ability in Bash or Python to automate tasks.
• Experience running hardware RMAs with vendors or driving issues to closure with outside parties.
• Methodical troubleshooting: isolate variables and document evidence.

Responsibilities

• Run server and GPU burn-in and stress testing; interpret results to decide production readiness.
• Triage failures across GPUs, memory, drives, NICs, PSUs, and cabling; reproduce, isolate, and document fault.
• Work servers out-of-band via IPMI and Redfish for power, BIOS, and sensor data collection.
• Apply firmware updates across fleet following baselines and rollout process.
• Drive RMAs with vendors from ticket to replacement and return of failed parts.
• Keep NetBox asset, serial, and replacement history accurate for every rack.
• Track failure patterns across fleet and flag recurring parts/firmware versions.
• Improve runbooks and automate repetitive steps; partner with data-center operations during turn-ups.
• Participate in on-call and escalation rotation for hardware issues.
