Resumo da oferta

Lintasarta is seeking an L2 Engineer to own incident tickets from escalation to hardware-level resolution in a large-scale GPU cloud. The role operates onsite 24x7 and requires hands-on fault diagnosis across GPU compute, liquid cooling, network fabric, and server infrastructure.

You will document root-cause analyses, manage changes through CAB, and coordinate formal escalations to L3/OEM with complete evidence. Strong RCA writing and vendor escalation experience are essential for success.

Qualificações

• 3–5 years in data center / infrastructure operations.
• Hands-on experience with GPU servers / HPC clusters.
• Strong GPU diagnostics: nvidia-smi, PCIe/NVLink, thermal and power analysis.
• Experience with liquid cooling systems including CDU and secondary loop.
• Familiarity with NVIDIA InfiniBand and converged networking.
• Proven RCA documentation and technical writing abilities.

Responsabilidades

• Performs in-depth fault diagnosis and hardware-level resolution across the full infrastructure stack, including GPU server faults, liquid-cooling anomalies, and enterprise networking.
• Authors Root Cause Analysis (RCA) documentation for every incident with timelines and preventive recommendations.
• Governs infrastructure changes through the CAB and coordinates change activities and verification.
• Initiates formal escalation to L3/OEM with complete evidence packages when needed, retaining ticket ownership.
• Maintains firmware/driver baseline compliance and monitors OEM notices with backup retention.
• Supports knowledge transfer through shadowing of IOH operational counterparts.

Descrição da oferta de emprego

The L2 Engineer is the technical resolution authority for all infrastructure faults that exceed L1's first-response capability. Operating onsite 24×7, L2 engineers own each incident ticket from the point of escalation through to hardware-level resolution or formal handoff to L3, maintaining ticket ownership throughout the entire escalation lifecycle. The role demands deep, hands-on expertise across GPU compute, liquid-cooling systems, high-speed network fabric, and server infrastructure in a large-scale, mission-critical GPU cloud environment.

Key Responsibilities:

• Performs in-depth fault diagnosis and hardware-level resolution across the full infrastructure stack, including GPU server faults (card detection, PCIe/NVLink link status, thermal and power anomalies, ECC error tracking), liquid-cooling system anomalies (CDU and secondary loop: inlet/outlet temperature, flow rate, differential pressure), NVIDIA InfiniBand and converged network faults, and enterprise server and storage issues.
• Authors Root Cause Analysis (RCA) documentation for every incident, capturing fault timeline, diagnostic findings, actions taken, and preventive recommendations.
• Governs all infrastructure changes through the CAB, accountable for change request submission, approval coordination, maintenance window execution, rollback planning, and post-change verification.
• Initiates formal escalation to L3/OEM with a complete evidence package (diagnostic logs, DCGM output, hardware status reports, incident timelines) when standard diagnostic and replacement procedures are exhausted, while retaining ticket ownership until full resolution.
• Maintains firmware and driver baseline compliance across all in-scope infrastructure, monitoring CVE advisories and OEM bulletins, executing baseline drift corrections within approved maintenance windows, with minimum 90-day configuration backup retention.
• Supports the knowledge transfer programme through a shadow/pairing model with IOH's embedded operational counterparts from service commencement.

Qualifications & Skills:

• Min. 3–5 years in Data Center / infrastructure operations, with direct hands-on experience on GPU servers / HPC clusters (not general servers only).
• In-depth GPU diagnostics (nvidia-smi/lspci, PCIe/NVLink, thermal & power, ECC error tracking).
• Rack-scale GB200 NVL72 (Schedule A - Voltage).
• Liquid-cooling systems (CDU & secondary loop), operation, monitoring, and anomaly handling (Schedule A - Voltage).
• NVIDIA InfiniBand + converged/management networking.
• Enterprise server & storage: fault isolation & vendor escalation.
• Strong RCA documentation and technical writing skills.
