Senior OpenStack & GPU Infrastructure Architect; Position Remote

Position Summary:

OCI Threads is seeking an experienced, highly technical, and accomplished Senior Open Stack & GPU Infrastructure Architect (Second Opening) to join our team in a remote capacity. In this specialized private cloud and artificial intelligence infrastructure role, you will spearhead designing, deploying, validating, and optimizing large-scale Open Stack and NVIDIA GPU computing environments. You will work closely with cross-functional software architects, data science squads, and enterprise stakeholders to architect robust compute, network, storage, and GPU acceleration platforms.

Ideal candidates bring a strong academic background in computer science or electrical engineering, deep practical mastery of hardened Linux systems, NVIDIA DCGM/NCCL tool chains, and Open Stack core services, with immediate availability for remote deployment.

As a Senior Open Stack & GPU Infrastructure Architect at OCI Threads in a remote capacity, you will take full ownership of leading architecture workshops, developing High-Level (HLD) and Low-Level (LLD) designs, and driving infrastructure-as-code deployments. Your day-to-day responsibilities encompass capacity planning, configuring Open Stack core components (Nova, Neutron, Cinder, Glance, Placement, Horizon), integrating NVIDIA GPU/HGX hardware, and validating driver stacks, Fabric Manager, and DCGM monitoring.

You will perform NCCL bandwidth testing, GPU burn-in, resiliency validations, and complex troubleshooting across multi-node private cloud clusters. Working in a fast-paced enterprise environment, you will prepare comprehensive operational runbooks, conduct technical knowledge transfer sessions, and provide tier-3 architectural support.

• Lead Open Stack architecture workshops, High-Level Design (HLD), and Low-Level Design (LLD) development.
• Design enterprise compute, network, storage, GPU acceleration, and security infrastructure architectures.
• Perform comprehensive capacity planning, infrastructure sizing, and hardware resource forecasting.
• Design and support hardened Linux-based Open Stack environments across control and compute planes.
• Lead Infrastructure-as-Code (IaC) based Open Stack deployment across control and compute nodes.
• Configure, administer, and troubleshoot Open Stack core services including Nova, Neutron, Cinder, Glance, Placement, and Horizon.
• Design and enable high-performance GPU workloads and container runtime integration.
• Review BIOS, BMC, GPU/HGX, NVMe, and NIC firmware compatibility across enterprise hardware.
• Implement, configure, and validate the NVIDIA driver stack, Fabric Manager, and Data Center GPU Manager (DCGM).
• Perform NCCL bandwidth testing, GPU burn-in, and performance validation across AI cluster nodes.
• Lead functional, performance, resiliency, failover, and disaster recovery testing.
• Provide L3 Open Stack architecture, platform troubleshooting, and operational support.

• Bachelor’s degree in Computer Science, Electrical Engineering, Information Technology, or a related field.
• Minimum 8+ years of professional IT infrastructure architecture and cloud engineering experience.
• Strong, proven hands‑on experience designing and implementing enterprise Open Stack private cloud environments.
• Deep technical knowledge of Open Stack compute, networking (Neutron), and storage architecture.
• Strong Linux infrastructure administration and automation / Infrastructure-as-Code (IaC) experience.
• Hands‑on experience with NVIDIA GPU infrastructure, DCGM, Fabric Manager, and NCCL benchmarking.
• Demonstrated expertise in High Availability (HA), disaster recovery, performance tuning, and complex troubleshooting.
• Ability to independently develop comprehensive HLD, LLD,…
