Infosys - Senior Technologist - Artificial Intelligence

About the Role:Infosys Strategic Technology Group (STG) is the deep tech innovation engine of Infosys, driving next generation platforms, AI first products, and applied research at scale. We work at the intersection of AI research, engineering rigor, and real world impact. If you want to build AI systems, not demos, this is where you belong.What you will do :- Design and build production grade AI/ML & GenAI systems (LLMs, vision, multimodal, decision AI)- Architect end to end GenAI pipelines: data, training/fine tuning, inference, and monitoring- Build Agentic AI systems using tool calling, planning, memory, orchestration, and feedback loops- Implement RAG architectures, embeddings, vector search, retrieval optimization, and evaluation- Work with LLMs (open & closed), fine tuning (LoRA/PEFT), prompt engineering, and alignment- Optimize inference for latency, cost, and scale (quantization, batching, GPUs)- Build MLOps/LLMOps pipelines: CI/CD, model versioning, monitoring, and drift detection- Deploy AI systems on cloud native stacks (AWS/Azure/GCP) and KubernetesTech Stack :- Programming: Python (mandatory); Java/C++ a plus- AI/GenAI: LLMs, Transformers, Diffusion models, RAG pipelines, vector databases (FAISS, Milvus, Pinecone)- Frameworks: PyTorch, JAX, TensorFlow, LangGraph, CrewAI- Infrastructure: Kubernetes, Microservices, MLOps tools, Feature stores, Model registriesWhat Sets You Apart :- Experience in AI research labs, product companies, or deep tech startups- Publications, patents, Kaggle/ICML/NeurIPS exposure- Open source contributions- Experience building AI platforms or developer facing systems (ref:hirist.tech)
