Job Summary

 

Hands-on AI Consultant to design and operationalize domain SLM, RAG / GraphRAG, and multi-turn agentic solutions—from enterprise data ingestion and fine-tuning to low-latency serving, APIs, security, observability, HA/DR, and governance. 

Key Responsibilities

Design enterprise GenAI platforms and domain SLMs using Gemma, Llama, Qwen, Phi, Mistral. Build agentic workflows for triage, diagnosis, remediation, approvals, escalation, and ticket automation. Develop ingestion pipelines for PDF, DOCX, PPTX, XLSX, SharePoint, APIs, and email, including OCR, deduplication, ACL preservation, lineage, monitoring, and PII controls. Lead SFT, LoRA/QLoRA, DPO/RLHF, distillation, quantization, and model compression. Architect RAG/GraphRAG using Qdrant, Neo4j, AuraDB, or Neptune with hybrid search, reranking, citations, and grounded retrieval. Deploy and optimize inference with vLLM, TensorRT-LLM, Triton, TGI, or SGLang, including batching, caching, streaming, autoscaling, and model routing. Build OpenAI-compatible APIs with tool calling, authentication, RBAC, rate limiting, and audit logging. Manage production deployments using Docker, Kubernetes, Helm, Terraform, CI/CD across Azure, AWS, and GCP. Define evaluation metrics for quality, grounding, hallucination, safety, latency, throughput, availability, and cost. Implement guardrails, observability, OpenTelemetry tracing, drift detection, governance, and compliance controls.
