The opportunity

Join the Win Labs NVIDIA Tower to design and deliver agentic, enterprise grade AI systems—from LLM/VLM powered applications and RAG/GraphRAG knowledge systems to multi agent automations—on the NVIDIA AI Enterprise stack (NeMo, NIM, Triton, TensorRT) and hyperscale clouds. You’ll build secure, performant AI architectures that ship to production across industries, integrating with modern data platforms and lakehouses (Snowflake/Databricks).

Your key responsibilities

• Architect end to end solutions: data ingestion → retrieval (hybrid + rerank) → RAG/GraphRAG → orchestration → inference → observability; design for latency, cost, accuracy.
• Design multi agent systems (hierarchical/peer to peer/ReAct) with shared memory (short term state, vector DB, knowledge graph), tool use, planning, and guardrails.
• Productionize on NVIDIA AI Enterprise: package models as NIM microservices, optimize with Triton/TensorRT, track with LLMOps (evals, canary, drift).
• Implement Responsible AI: safety (hallucination mitigation, jailbreak detection), privacy/PII, bias testing, lineage/citations; align to NIST AI RMF / ISO 42001 where relevant.
• Integrate with enterprise platforms (M365/Copilot, CRM/ERP/ITSM), lakehouse (Snowflake/Databricks), and vector stores (pgvector, Pinecone, Milvus).
• Deliverables: reference architectures, security blueprints, Bill of Materials (SBOM), VEX, deployment runbooks, cost models/TCO.
• Mentor engineers (Python/PyTorch), enable squads on LangChain/LangGraph, retrieval evaluation, and AgentOps/LLMOps.

Skills and attributes for success

• Proven experience taking GenAI from POC → production at scale, with measurable KPI lift (precision, latency, cost/1K tokens). (Market benchmark: Accenture/Deloitte senior roles emphasize E2E platform and governance.)
• Deep stack fluency: NeMo, NIM, NVIDIA Triton, TensorRT; or equivalent cloud AI runtimes.
• RAG architectures (hybrid retrieval + cross encoder reranking), query transformation (multi query/HyDE), GraphRAG; vector DB selection & scaling.
• Security & governance for AI platforms (HITL, audit trails, content filtering, citations), multi region data residency.
• Strong stakeholder communication and solution storytelling; hands on mindset.

To qualify for the role, you must have

• B.Tech/M.Tech/MCA (CS/EE/Math) or equivalent
• 5–8 years total with 3+ in enterprise AI/ML; shipped at least 2 production LLM solutions (RAG/agentic). (Peers: Wipro/HCL mid senior roles highlight similar thresholds.)
• Hands on Python, PyTorch, CUDA familiarity; containers (Docker), Kubernetes; CI/CD, IaC, telemetry.
• Cloud depth in Azure/AWS/GCP; exposure to Bedrock, Vertex, Azure AI.

Ideally, you’ll also have

• Knowledge graph/ontology modeling for DLMs; Snowflake/Databricks governance; RAG evaluation (RAGAS), prompt security.
• Familiarity with NVIDIA Blueprints and Nemotron reasoning models (e.g., Nemotron Super) for agentic workloads.

What we look for

• A Team of people with technical consulting and architecting experience and enthusiasm to learn new things in this fast-moving environment
• A leader with technical consulting and architecting experience, passionate about innovation in 3D and Metaverse technologies.
• An opportunity to be part of a market-leading, multi-disciplinary team, shaping the future of digital collaboration.
• Enthusiasm for learning new technologies and driving change in a fast-moving environment.
