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.
