AI/ML Developer

We are looking for experienced AI/ML Engineers who can build and productionize enterprise-grade Machine Learning, Generative AI and Agentic AI solutions.

The ideal candidate will combine strong Python and Machine Learning fundamentals with hands-on experience in AWS AI/ML services, Retrieval-Augmented Generation (RAG), LLM integration and agentic workflows. You should be comfortable taking solutions from experimentation and model development through deployment, evaluation, monitoring and production operations.

This is a hands-on engineering role for professionals who have built real ML/GenAI solutions rather than only experimented with LLM APIs.

Responsibilities

Design and deploy end-to-end ML and Generative AI pipelines on AWS using Amazon SageMaker and Amazon Bedrock.

Build intelligent LLM-powered agents and Agentic AI workflows using LangGraph and/or LangChain.

Architect production-ready RAG solutions, covering document ingestion, chunking, embeddings, metadata, vector indexing, retrieval and response generation.

Develop and productionize ML models for use cases such as forecasting, recommendations, prediction and customer analytics.

Integrate foundation models and LLM APIs including Amazon Bedrock and OpenAI into scalable enterprise applications.

Engineer robust prompting, context-management and tool-calling/orchestration workflows for LLM applications.

Implement LLM evaluation, grounding, hallucination mitigation and responsible-AI guardrails.

Build semantic and hybrid retrieval solutions with vector/search technologies such as FAISS, Pinecone and OpenSearch.

Apply MLOps/LLMOps principles for model and application deployment, versioning, evaluation, monitoring and lifecycle management.

Develop scalable Python-based APIs and services to expose AI/ML capabilities to downstream applications.

Collaborate with data engineers, architects, product teams and cloud/platform engineers to move AI solutions from prototype to production.

The emphasis on RAG construction, evaluation, production agents, vector indexing and LangGraph/LangChain closely reflects recent Infosys internal AI engineering requiremen
