About the Role

As Domain Architect - AI Compute, you will be the primary technical authority for the physical and logical lifecycle of high-performance GPU compute fleets across a diverse portfolio of client environments, bridging the gap between architectural design and hands-on execution. You are a builder as much as an advisor: as comfortable configuring a cluster from the CLI as you are explaining that configuration to a C-level audience.

As a global systems integrator, we don't simply operate static cloud environments. We design and deliver purpose-built, high-scale AI factories for some of the world's leading enterprises. In this role you will define the reference standard for compute infrastructure, moving beyond single-server administration to architect repeatable, scalable, and automated compute fabrics. You will act as technical lead on NVIDIA Cloud Partner (NCP) and private enterprise AI cloud deployments, owning the compute layer of the compute, network, and storage stack.

Your time will be split roughly 60/40 between delivering complex AI infrastructure (60%) and providing pre-sales subject matter expertise (40%). You will lead the physical provisioning of NVIDIA DGX SuperPOD, NVIDIA DGX BasePOD, and Cisco AI POD environments, ensuring clients inherit platforms that are genuinely ready for day-2 operations, while helping the sales team scope and cost future deployments.

Key Responsibilities

Delivery and implementation

Bare-metal build and provisioning

• Lead the physical provisioning of GPU platforms and clusters, including NVIDIA GB200/GB300 NVL72 rack-scale systems, NVIDIA DGX SuperPOD and DGX BasePOD reference architectures, HGX- and MGX-based systems, and Cisco AI PODs.

• Use NVIDIA Base Command Manager (BCM) for cluster provisioning, diskless boot, image management, and firmware lifecycle management.

• Harden and baseline the host operating system across the fleet.

• Establish cluster monitoring and lifecycle management with NVIDIA Mission Control.

• Build and execute zero-touch provisioning (ZTP) workflows that turn bare-metal hardware into production-ready nodes.

Scheduler and workload configuration

• Define and enforce fair-share policies, fractional GPU allocation using Multi-Instance GPU (MIG), and preemption logic for multi-tenant environments.

• Ensure orchestration layers respect hardware topology, including NUMA affinity and PCIe topology, to protect performance.

• Implement and tune advanced schedulers: Slurm on bare metal, and NVIDIA Run:ai, Kueue, or Volcano on Kubernetes.

Orchestration and day-2 operations

• Deploy and configure multi-cluster management and observability platforms such as Rafay.

• Implement high-fidelity telemetry using NVIDIA Data Center GPU Manager (DCGM) to monitor GPU health, thermal throttling, and Xid error rates.

• Lead the transition to day-2 operations, ensuring the environment is fully integrated with the client's identity providers and storage backends before handoff.

Performance engineering

• Conduct acceptance and validation testing using NCCL tests and HPL to verify cluster performance against expected baselines.

• Perform kernel and OS-level tuning (hugepages, sysctl, and driver parameters) to optimize for high-bandwidth InfiniBand and RoCEv2 fabrics.

Pre-sales SME and consulting

Technical scoping and estimation

• Support the sales team by validating customer technical requirements and producing accurate level-of-effort (LOE) estimates for statements of work.

• Define the standard operating environment (SOE) used in proposals to ensure repeatability across engagements.

Bill of materials validation and architecture

• Own the technical accuracy of the compute bill of materials.

• Verify that all components, including memory, NVMe storage, NICs, and optical transceivers, are aligned with NVIDIA-Certified Systems requirements and the qualified component lists in the relevant DGX, HGX, MGX, and NVL72 reference architectures.

• Match GPU platform selection to the client's actual workload profile and growth expectations.

Client workshops

• Lead technical discovery workshops to determine workload requirements, distinguishing between the very different infrastructure profiles of traditional machine learning, LLM training, LLM inference, and Omniverse digital twin and visualization workloads.
