Platform Support Architect

Job Description

DDN is expanding its Enterprise and Sovereign AI Solution offerings, particularly focusing on HyperPOD - a turnkey NVIDIA AI Data Platform built on DDN Infinia storage, NVIDIA AI Enterprise (NVAIE), and Supermicro reference hardware, optimized for inference and RAG workloads. Our support organization is deeply experienced in storage (Infinia, EXAScaler); we are now hiring an AI platform specialist to lead supportability and enablement for the AI side of the stack.

• NVIDIA AI Enterprise services (e.g., NIMs, NeMo, Triton, GPU Operator, licensing/NLS)
• Vector databases (initially Milvus)
• RAG/agentic workflows
• High-performance storage and networking fabric

Key Responsibilities

Act as the primary NVIDIA AI Enterprise and vector database solutions expert for HyperPOD customer environments, guiding diagnosis, optimization, and solution design. Own complex end-to-end triage across GPU, NVAIE services, vector DB, Kubernetes, Docker, high-speed networking, and Infinia storage, distinguishing product defects from environmental and integration issues.

• Diagnose and resolve performance bottlenecks in RAG and agentic AI workflows, from model selection and prompt/RAG configuration through to vector search, GPU utilization, and data access patterns.
• Collect and interpret logs and telemetry across Linux, containers, Kubernetes, GPU stack, vector DB, and storage/networking; build minimal repros and high-quality defect reports for escalation to NVIDIA, vector-DB vendors, OEMs, and internal engineering.

Supportability

Author and maintain support triage runbooks and checklists for HyperPOD covering NVAIE services, Milvus/vector DB, GPU stack, Docker, Kubernetes resources, and their interaction with Infinia and the network fabric. Define and validate unified diagnostics bundles that capture the right logs/configs/metrics from all relevant layers (Infinia, GPUs, NVAIE, Milvus, Kubernetes, network) to enable fast problem isolation and high-signal escalations.

• Collaborate with observability and tools teams to shape Prometheus/Grafana/ELK/NetQ or equivalent dashboards that surface both platform health and RAG/service-level metrics (e.g., TTFT, retrieval latency, error rates, throughput).

Enablement, PoCs, and Reusable Assets

Build hands-on labs and PoCs that mirror customer RAG and agentic AI use cases on HyperPOD, validating supportability and capturing "known good" configurations and troubleshooting patterns. Develop reusable technical assets – implementation guides, best-practice playbooks, tuning checklists, example architectures – to accelerate time-to-value for customers, PS, and Support.

• Design feedback, readiness, and cross-functional leadership
• Provide structured feedback from early field cases and PoCs into Product Management and Engineering on stack compatibility, upgrade order, rollback constraints, and observability needs for NVAIE, Milvus/cuVS, Infinia, and networking.
• Collaborate closely with NVIDIA solutions architects, OEM architects, PS, and Support Innovation to align reference architectures and best practices with real-world support experience.

Required Experience & Skills

• Technical: 5+ years in Linux-based infrastructure roles (SRE, MLOps, platform engineering, or L2/L3 support) supporting production systems; 8+ years total technical experience preferred.
• Hands-on experience with containers and Kubernetes (Docker/containerd, Helm, Operators; debugging pods, DaemonSets, CSI, CNI, and ingress/load balancers).
• Demonstrated experience operating GPU-accelerated workloads in production: NVIDIA GPUs, drivers, CUDA concepts, GPU utilization/perf triage NVIDIA GPU Operator and Kubernetes-based GPU lifecycle management.
• Familiarity with DGX / HGX or similar GPU cluster platforms.
• Practical experience with AI storage and networking for HPC/AI clusters: High-performance storage systems (e.g., EXAScaler/Lustre, GPFS, Ceph, distributed object storage, enterprise NAS/SAN).
• RDMA-accelerated and/or high-speed Ethernet/InfiniBand networking, including fabrics, switch topologies, and large-scale deployments.
• Hybrid cloud or cloud-adjacent patterns (Kubernetes CSI, cloud-native fabrics, data locality).
• Experience with one or more vector databases (Milvus, Qdrant, Pinecone, pgVector, OpenSearch/Elasticsearch vectors, etc.), including schema design, ingestion, and operations.
• Solid understanding of RAG and Generative AI workflows: embeddings, retrieval, reranking, prompt design, context management, and how these interplay with vector search and GPU inference at scale.
• Familiarity with NVIDIA AI Enterprise components and toolchain, for example: NVIDIA NIM inference microservices NVIDIA NeMo framework / NeMo Retriever / NeMo Curator Triton Inference Server, TensorRT / TensorRT-LLM, CUDA libraries NVIDIA blueprints for enterprise RAG and agentic AI.
• Experience designing, operating, or supporting MLOps / GenAI pipelines: CI/CD for models, deployment strategies, canarying/rollback, GPU resource management, monitoring and alerting for AI services.
• Strong diagnostic skills across Linux, containers, Kubernetes, GPUs, storage, and networking; able to quickly narrow fault domains and propose experiments or configuration changes.
• Support, architecture, and stakeholder skills: Track record of building reusable technical assets (runbooks, KBs, implementation guides, benchmarks, PoC templates) that improve support readiness and partner/customer success.
• Excellent communication skills, capable of clearly explaining complex AI platform topics to both engineers and executive stakeholders, internally and with partners.

Preferred Qualifications

• Prior experience with scale-out storage in GPU/AI environments.
• Direct experience crafting and operating RDMA-accelerated HPC/AI clusters at scale, including spine-leaf or fat-tree network designs and large switch/router deployments.
• Hands-on work with NVIDIA reference blueprints (Enterprise RAG, VSS, AIQ, industry-specific blueprints) or similar enterprise AI architectures.
• Familiarity with AI observability and responsible AI practices (guardrails, monitoring for drift/toxicity, basic understanding of regulatory considerations like GDPR/HIPAA in the context of AI systems).
• Experience with observability stacks (Prometheus, Grafana, Loki/ELK, NetQ, etc.) tuned for AI workloads, including service-level dashboards and SLOs.

What Success Looks Like in This Role

Within 6-12 months, a successful AI Data Platform Solutions Architect will have:

• Become the go-to internal expert for "how this AI and networking stack actually works in production" across Support, PS, Product, and NPI for HyperPOD.
• Drive speed and quality of support at solution level; NVAIE, vector DB, and AI-workflow issues through high-quality diagnostics, architecture insight, and well-defined "golden stack" patterns.
• Established clear, repeatable triage and escalation patterns for AI-side incidents that L1/L2 storage engineers can follow with confidence.
