Title : Senior GenAI Engineer — RAG (Full-Stack)

Experience : 5+ years

Location : Remote

Work type : Chennai - Work from Office/ Remote – Other locations

Employment Type : Full Time

Notice Period : Immediate

Work Day :Mon to Fri

Key Responsibilities:

- RAG pipeline end to end: ingestion integration, hybrid retrieval with reranking, prompt/context strategy, citation resolution, refusal behavior
- Permission-aware retrieval: source ACL mapping (SharePoint/Entra, Confluence) to fail-closed retrieval filters; zero-leakage test suite partnership with QA
- Vector database design and operations (Milvus or pgvector): schema, metadata filters, sync, performance
- Full-stack product build: React/TypeScript chat and citation experience, Python/FastAPI services, REST APIs, SSO/OIDC integration, admin configuration UI
- Evaluation-driven development: retrieval precision, faithfulness, and citation-accuracy metrics as the daily working loop; A/B testing of retrieval and prompt variants
- Latency engineering to the 3–5s first-token / ~15s complete-answer targets at concurrency

Technical Skills:

- 5+ years software engineering with 2+ years building RAG/LLM applications in production — with real users and real quality metrics, not notebooks
- Deep retrieval craft: chunking strategy, embeddings, hybrid search, rerankers; you can explain why retrieval fails and how you measured the fix
- Genuine full-stack evidence:



shipped React/TypeScript front ends AND Python back-end services in production; API design; OIDC/SAML integration
- Vector database production experience (Milvus, pgvector, Weaviate, or equivalent) including permission/metadata filtering
- Evaluation fluency: has built or operated a retrieval/answer quality harness with numeric thresholds

Strongly Preferred:

- Permission-aware/multi-tenant retrieval specifically; Microsoft Graph API; NIM/OpenAI-compatible serving endpoints; streaming UX; enterprise design systems; banking content domains
