Resumo da oferta

Lintasarta is seeking an experienced L2 Engineer to resolve GPU server and infrastructure faults in a large-scale GPU cloud environment. The role operates onsite 24×7, owning incidents from escalation to hardware-level resolution and handoff to L3.

Expertise in GPU diagnostics, liquid cooling, InfiniBand networking, and RCA documentation is required. Candidates should have 3–5 years in data center operations, hands-on GPU/HPC experience, and strong technical writing skills in English and Bahasa.

Qualificações

• 3–5 years in Data Center / infrastructure operations with hands-on GPU servers / HPC clusters
• In-depth GPU diagnostics (nvidia-smi, lspci, PCIe/NVLink, thermal and power)
• Rack-scale NVL72 and server hardware familiarity
• Liquid-cooling systems operation and anomaly handling (CDU & secondary loop)
• NVIDIA InfiniBand and converged networking experience
• Enterprise server & storage fault isolation and vendor escalation
• Strong RCA documentation and technical writing skills
• English & Bahasa language proficiency

Responsabilidades

• Performs in-depth fault diagnosis and hardware-level resolution across GPU servers and storage infrastructure.
• Authors Root Cause Analysis (RCA) documentation for every incident with timelines and actions.
• Governs infrastructure changes through CAB; manages change requests and verifications.
• Initiates formal escalation to L3/OEM with complete evidence package when needed.
• Maintains firmware and driver baseline compliance; monitors CVE advisories and OEM bulletins.
• Supports knowledge transfer via shadow/pairing with IOH counterparts.

Descrição da oferta de emprego

About the Role:

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).
• Server B300 (Schedule B & C – Penguin & Taylor Swift).
• 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.
• Language : English & Bahasa
