Staff Software Engineer – AI Agent/ Agentic Focus at Visa

Visa is building a next-generation Agentic AI Platform that brings intelligent, autonomous agents into large-scale distributed applications across our global ecosystem. We’re seeking a Staff Software Engineer who will design and build scalable backend systems that integrate AI agents into Visa’s enterprise infrastructure. You will work with other engineers and technical leaders to define the architecture, scaling strategy, and engineering standards for Visa’s AI-driven products. This is a role for a self-driven engineer — a go-getter, builder, and problem solver with deep experience in Java microservices, GenAI integration, and distributed system design, and a true-north, entrepreneurial mindset focused on speed, quality, and innovation. Essential Functuion:  • Architecture & Design: • Architect and evolve the Agentic AI Platform to support multi-agent orchestration, retrieval-augmented generation (RAG), and integration with existing Visa microservices. Design scalable, secure backend systems using Java (Spring Boot) and Python (FastAPI/Flask). Develop RESTful and gRPC APIs that connect backend services, AI agents, and React front-end applications. • AI & GenAI Integration: • Integrate Large Language Models (LLMs) such as GPT, Claude, Mistral, and Gemini into backend systems. Build and optimize RAG pipelines using vector databases (Pinecone, Weaviate, FAISS). Develop orchestration and agentic workflows using LangChain, LangGraph, or Autogen. • Scalability & Reliability: • Lead the design and implementation of distributed, fault-tolerant systems that scale horizontally. Implement auto-scaling, monitoring, and observability using Kubernetes, Docker, and Prometheus/Grafana. Drive best practices for latency reduction, cost optimization, and service reliability. • Leadership & Execution: • Partner with other senior engineers, ML engineers, and product leads to define and deliver the platform roadmap. Mentor developers, set coding standards, and lead design reviews. Deliver results with urgency — balancing innovation with enterprise rigor. • Innovation & Strategy: • Explore new frameworks, architectures, and deployment models to push the boundaries of Agentic AI in production. Drive continuous improvement, automation, and open-source adoption across the engineering organization.This is a hybrid position.
