• Build and optimize Retrieval-Augmented Generation (RAG) pipelines.
• Develop LLM workflows, AI Agents, and multi-agent solutions.
• Integrate LLMs such as OpenAI/Azure OpenAI, Claude, Gemini, or open-source models into enterprise applications.
• Implement prompt engineering, function/tool calling, structured outputs, and LLM evaluation techniques.
• Develop scalable backend services and REST APIs using Python, FastAPI, or Flask.
• Build responsive frontend applications using React.js, Next.js, Angular, or similar frameworks.
• Integrate GenAI solutions with enterprise applications, APIs, databases, and third-party platforms.
• Work with Vector Databases such as Pinecone, FAISS, Chroma, Weaviate, or Azure AI Search.
• Implement document ingestion, chunking, embedding, retrieval, reranking, and response-generation pipelines.
• Deploy and manage AI applications on Azure, AWS, or GCP.
• Implement authentication, security, logging, monitoring, and performance optimization.
• Work closely with Product, Data, AI, and business teams to translate requirements into production-ready solutions.
• Troubleshoot production issues and continuously improve AI application quality, latency, accuracy, and scalability.

Must-Have Skills

• 4–12 years of overall software engineering experience with hands-on GenAI development experience.
• Strong programming skills in Python.
• Hands-on experience with Generative AI, LLMs, RAG, Prompt Engineering, and AI Agents.
• Experience with frameworks such as LangChain, LangGraph, LlamaIndex, Semantic Kernel, or equivalent.
• Strong backend development experience with FastAPI/Flask and REST APIs.
• Full Stack development experience using React.js / Next.js / Angular and JavaScript/TypeScript.
• Experience with SQL and NoSQL databases.
• Hands-on knowledge of Vector Databases and Embeddings.
• Experience with at least one major cloud platform: Azure, AWS, or GCP.
• Knowledge of Git, Docker, CI/CD, and microservices architecture.
• Strong debugging, analytical, and problem-solving skills.

Good to Have

Experience with Azure OpenAI, AWS Bedrock, or Google Vertex AI.

Knowledge of MLOps/LLMOps, model evaluation, monitoring, and guardrails.

Experience developing enterprise-grade AI Agents and Agentic AI workflows.

Exposure to Kubernetes and container orchestration.
