Job Description

We are looking for an experienced L2 Engineer to operate and support high-performance AI infrastructure platforms, including NVIDIA GPU clusters, InfiniBand fabrics, and Kubernetes-based IaaS environments.

This role focuses on deep infrastructure expertise, ensuring performance, scalability, and reliability of the platform layer that powers AI workloads — without being responsible for the workloads themselves.

You will play a key role in bare metal lifecycle management, advanced InfiniBand troubleshooting, and platform stability, working closely with engineering teams to operate cutting-edge infrastructure at scale.

Key responsibilities:

• Troubleshoot and maintain InfiniBand fabrics, including performance tuning, link issues, and topology validation.
• Act as the escalation point for L1 for complex infrastructure and hardware issues.
• Own and maintain accurate infrastructure modeling, IPAM, and source-of-truth data in NetBox.
• Own InfiniBand fabric management and advanced troubleshooting, utilizing Verity for configuration, monitoring, and optimization of high-performance interconnects. 
• Diagnose and resolve issues across GPU servers, networking, storage, and Kubernetes platforms.
• Perform deep hardware and system-level diagnostics (GPUs, PCIe, NICs, firmware, etc.).
• Support Kubernetes platform stability (node health, networking, scheduling issues).
• Contribute to automation of provisioning and operational workflows.
• Lead incident response, root cause analysis (RCA), and post-incident improvements.
• Collaborate with vendors and internal engineering teams on complex issues.
• Support infrastructure upgrades, firmware management, and capacity expansion.

Qualifications

 

Required Skills & Experience:

• 3–6+ years of experience in infrastructure operations, datacenter engineering, or cloud platforms.
• Strong Linux systems expertise.
• Hands-on experience with bare metal provisioning systems and lifecycle management.
• Strong experience with InfiniBand networking (troubleshooting, performance, fabric management using UFM).
• Experience with IPAM/DCIM tools such as NetBox and Ethernet network configuration and validation leveraging Verity.
• Solid understanding of datacenter networking, storage, and hardware architecture.
• Working knowledge of Kubernetes in production environments.
• Strong troubleshooting skills across hardware and distributed systems.

Preferred

qualifications

:

• Experience with NVIDIA GPU platforms and accelerated computing infrastructure.
• Familiarity with automation tools (Terraform, Ansible, etc.).
• Exposure to OpenStack (optional).
• Experience with observability stacks (Prometheus, Grafana, ELK).

Success in this role:

• Rapid resolution of complex infrastructure and networking issues.
• High reliability and performance of InfiniBand and GPU infrastructure.
• Scalable and efficient bare metal provisioning processes.
• Strong contribution to automation and operational excellence.
• Trusted escalation point and technical leader within the team.

Additional Information

We offer:

• Work with an established Silicon Valley leader in the cloud infrastructure industry;
• Work with exceptionally passionate, talented and engaging colleagues, helping Fortune 500 and Global 2000 customers implement next-generation cloud technologies;
• Be a part of cutting-edge, open-source innovation;
• Thrive in the high-energy environment of a young company where openness, collaboration, risk-taking, and continuous growth are valued;
• Professional development and training;
• Attend conferences and working groups;
• Company outings, happy hours, hackathons, and tech talks;
• Receive a competitive compensation package with a strong benefits plan.
