Software Engineer, Sr. Consultant Level (11-15 Years Exp, Java-python-aws-genai)

Visa Visa · Fintech · Bengaluru, India, IN

Visa is seeking a Sr. Consultant Software Engineer to architect, design, and build scalable backend systems for their next-generation Agentic AI services. This role involves integrating AI agents into enterprise infrastructure, working with Java microservices, GenAI, and distributed systems. Responsibilities include architecting the Agentic AI Platform, integrating LLMs and RAG pipelines, leading the design of scalable systems, and defining evaluation metrics for AI and agent performance.

What you'd actually do

  1. Architect and evolve the Agentic AI Platform to support multi-agent orchestration, retrieval-augmented generation (RAG), and integration with existing Visa microservices.
  2. Integrate Large Language Models (LLMs) such as GPT, Claude, Mistral, and Gemini into backend systems.
  3. Build and optimize RAG pipelines using vector databases (Pinecone, Weaviate, FAISS).
  4. Develop orchestration and agentic workflows using LangChain, LangGraph, or Autogen.
  5. Define evaluation metrics and testing frameworks to measure LLM and agent performance, accuracy, latency, cost, and reliability in production.
