About the Role We are hiring GenAI Engineers to design and build production-grade Generative AI applications end-to-end, from backend services and APIs through to the user-facing screens. You will own the full lifecycle of RAG pipelines and agentic / multi-agent systems: ingestion, retrieval, orchestration, evaluation, and deployment. This is a hands-on engineering role for someone with software-engineering DNA, you build and ship applications, you care about code quality and system design, and you have moved into GenAI because you love building with it. You will work in a hybrid model out of Bangalore or Gurgaon, collaborating closely with product owners, tech leads and fellow engineers. What you'll do Build and own GenAI applications end-to-end, backend, integration, and frontend. Design and ship RAG pipelines: document ingestion and chunking, embeddings, vector search, hybrid retrieval and reranking, prompt construction, and citations. Build agentic / multi-agent systems orchestration, tool calling, state management, loop control, human-in-the-loop, and error handling. Make and defend system-design decisions for production: scalability, latency, caching, observability and cost. Set up evaluation and monitoring so quality, latency and cost are measured, not guessed. Must-Have Skills & Experience 4+ years of overall software-engineering experience, with a clear software-engineering background (backend, full-stack, or frontend developer who builds and ships applications). Strong backend ownership in at least ONE language, Python (preferred), Java, or Node.js, with genuine depth, not shallow exposure across several. Hands-on frontend JavaScript, plain JavaScript, React, or Angular (able to build and own UI screens). Proven, hands-on RAG experience: chunking strategy, embeddings, vector databases (e.g., Pinecone, FAISS, Chroma, Weaviate, pgvector), retrieval flow, and reranking. Agentic AI / multi-agent experience using frameworks such as LangChain, LangGraph, LlamaIndex, CrewAI or AutoGen with clear individual ownership ("I built / I owned"), ideally taken to production rather than POC only. Production system-design ability scalability, latency, caching, monitoring, reliability and cost trade-offs. Strong communication and the ability to walk through architecture decisions and trade-offs clearly. Nice-to-Have Skills & Experience MCP (Model Context Protocol) experience, connecting AI to external tools and data sources. Agent-to-agent (A2A) / multi-agent orchestration at scale. LLM evaluation & observability: RAGAS, LangSmith, Promptfoo, LLM-as-judge, tracing, cost/latency dashboards. Full-stack delivery with a modern frontend framework (React / Angular). Experience in BFSI, healthcare or large-enterprise environments. Cloud-native GenAI experience (e.g., AWS, including frameworks like Strands). Familiarity with hybrid retrieval (BM25 + semantic), cross-encoder rerankers, and cost-optimization techniques (caching, index pruning).
