Visa is building a next-generation services that brings intelligent, autonomous agents into large-scale distributed applications across our global ecosystem. We’re seeking a Sr. Consultant Software Engineer who will architect, design, and build scalable backend systems. You will work with other Senior 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 hands-on technical leader — 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.

Architecture & System Design:

• Design multi-tier, distributed systems using Java (Spring Boot) with clear domain boundaries and API contracts.
• Use REST for efficient service-to-service communication between microservices, AI agents, and front-end applications.
• Architect and evolve backend microservice platforms that support GenAI-driven capabilities, agent orchestration, and MCP-based model interactions.
• Design and implement Model Context Protocol (MCP) servers and clients to standardize model access, tool invocation, and context exchange across AI services.
• Ensure security-by-design, including authentication, authorization, data privacy, and compliance with enterprise standards.

Backend Microservices Engineering (Core Focus):

• Develop and own high-performance backend microservices using Java, Spring Boot, Kafka, MySQL and Event-driven and asynchronous processing patterns
• Lead the design of highly scalable, low-latency services that meet strict availability and throughput requirements.
• Apply engineering standards, SDLC best practices, and design patterns across the lifecycle of large-scale systems.
• Design and optimize database schemas, queries, and data access layers, ensuring reliability and performance at scale
• Independently deliver and evolve large, mission-critical applications and complex multi-tier solutions.

GenAI & Agentic AI Integration

•  Integrate LLMs like GPT, Claude ND Gemini securely and at scale into backend services.
• Design and implement agentic workflows using frameworks like LangChain, LangGraph, or enabling multi-agent orchestration and tool use.
• Use MCP to decouple model providers from application logic, enabling flexible model routing, observability, and governance.
• Collaborate with system engineers and ML engineers on AI-assisted and autonomous development life cycle capabilities, including AI-assisted coding and refactoring Autonomous testing and validation Intelligent CI/CD orchestration AI-driven observability and incident analysis

Scalability, Reliability & Observability

• Designed fault-tolerant, horizontally scalable systems using Kubernetes and Docker
•  Use Prometheus, Grafana, and distributed tracing tools for auto-scaling, monitoring, and alerting.
• Drive latency reduction, optimize costs, and enhance resiliency across backend and AI-enabled services.
• Use telemetry and production metrics to propose and implement architectural and performance enhancements.

Quality Engineering & DevOps

•  Design and build test automation frameworks (unit, integration, contract, load) to deliver quality software.
• Conduct code and design reviews to ensure all requirements are met.
• Support deployment pipelines, staging environments, and production releases.
• Develop and maintain deployment, rollback, and operations runbooks for large-scale systems.

Global Collaboration & Cross-Time zone Leadership 

• Collaborate closely with engineering teams in the United States and India, operating effectively across time zones. 
• Maintain the ability to work overlap hours to support real-time design discussions, incident response, and delivery milestones. 
•  Lead solution design and technical alignment with senior engineers and leads across geographies.
• Synthesize inputs from multiple teams to propose the best technical solutions, balancing scalability, maintainability, and business impact. 
• Act as a knowledge multiplier, sharing best practices, architectural insights, and emerging trends across regions.

Technical Leadership & Collaboration

• Partner with product managers, system engineers, and engineering teams to define and execute the technical roadmap.
• Mentor senior and mid-level engineers, setting  coding standards, architectural patterns, and best practices
• Provide technical guidance across teams, leveraging backend and AI platform expertise to unblock complex initiatives
• Balance innovation velocity with enterprise discipline to ensure solutions are production-ready and sustainable over the long term.

Innovation, Strategy & Continuous Improvement

• Evaluate and introduce new frameworks, architectures, and deployment models for backend systems and GenAI platforms.
• Drive adoption of open-source technologies, automation, and platform reusability.
• Shape long-term strategy for microservice based backend services, including governance, cost controls, and developer experience.
• Champion continuous improvement across code quality, system design, and operational excellence.

Key Differentiators of This Role

•  Backend-first Staff Engineer II with deep ownership of microservices and distributed systems.
• Production-grade GenAI integration, not experimental AI work.
• MCP-driven architecture to standardize model access, tooling, and agent interactions.
• Strong emphasis on scalability, reliability, and enterprise standards 

The Work itself: 

• Design code and systems that touch 40% of the world population while influencing Visa’s internal standards for scalability, security, and reusability 
• Collaborate multi-functionally to create design artifacts and develop best-in-class software solutions for multiple Visa technical offerings 
• Actively contribute to product quality improvements, valuable service technology, and new business flows in diverse agile squads 
• Develop robust and scalable products intended for a myriad of customers including end-user merchants, b2b, and business to government solutions. 
• Leverage innovative technologies to build the next generation of Payment Services, Transaction Platforms, Real-Time Payments, and Buy Now Pay Later Technology 
• Opportunities to make a difference on a global or local scale through mentorship and continued learning opportunities 

Essential Functions:

• Works directly with product owners to gather and refine requirements across products, adding and taking into account existing tools and solutions across the organization.
• Develops and designs advanced architect solutions that are robust and scalable, considering integrations with other solutions across the internal technical ecosystem.
• Provides domain expertise on the development of technical documentation of solutions and contributes to standard processes in technical documentation as needed.
• Plays a key role in the development and delivery of new features across products from end-to-end.
