Progress starts with you.\nJob Description\nJob Summary:\nSoftware Development Engineers are expert problem-solvers and builders who design, implement, and improve software applications and systems. In this role, engineers spend approximately60-75% of their time coding, working hands-on with code, data, and modern tools (including AI-assisted development, cloud services, and automation frameworks) to deliver secure, scalable, and high-quality technology solutions that drive business outcomes in the fintech sector. They collaborate with cross-functional teams - product managers, designers, data scientists, QA, operations, and compliance - to translate business requirements into robust technical solutions, all while adhering to best practices, security standards, and regulatory requirements.\nAs thetechnical lead of the Visa Assist AI platform, you will be a hands-on, technically deep, and influential engineer who owns thetechnical vision and deliveryof a multi-agent AI architecture (Visa Assist) serving Visa's client-facing channels - Chat, Email, and Portal. This is acoding-intensive leadership rolewhere you will architect, implement, and ship critical platform components while mentoring engineers, standardizing engineering practices, and aligning with stakeholders to shape the strategic roadmap for Visa's AI-powered client services.\nKey Responsibilities:\nCollaborate with business stakeholders and leadershipto interpret and translate requirements across the full VisaAssist portfolio - spanning inbound channels (Chat, Email, Portal), agent worker routing logic, and platform evolution roadmaps - incorporating feedback into technical architecture decisions and working code.\nTranslate business requirementsinto strategic roadmaps and tactical solutions - including routing logic adjustments, guardrail tuning, knowledge base curation, and CRM/billing workflow improvements - while escalating potential design issues and downstream dependencies to appropriate stakeholders.\nLead system design and architecture, personally architecting and building core infrastructure components: intent classification models, agent routing logic, MCP protocol adapters, and resilience patterns across the distributed multi-agent system.\nDrive program deliveryacross the full VisaAssist portfolio - intent classification & routing accuracy improvements, agent worker ecosystem (MsgProcessing, CrmDynamics, InvoiceInvestigator, ClientProfile, Transaction Management), MCP protocol adoption and expansion across external services (CRM, Invoice, CAD CP servers), and platform reliability.\nWrite production code daily (60%+ of time), personally implementing the most complex features across the full stack - FastAPI endpoints, LangChain agent orchestration, Pydantic v2 schemas, async NATS handlers, and Docker/Kubernetes configurations.\nEstablish and lead engineering standardsby implementing reference patterns for the Python / FastAPI / LangChain / Pydantic v2 stack, building shared library modules, and coding MCP server integration adapters (OAuth2 + SSE, mTLS + API Key, REST) that the team adopts as platform-wide standards.\nImplement LangChain agent patternsincluding multi-hop MCP and dynamic schema composition; prototype emerging technologies (agentic AI frameworks, MCP protocol evolution, RAG advancements) and recommend technical direction based on hands-on evaluation.\nApply advanced debugging techniquesto resolve the hardest production issues spanning multiple microservices, NATS messaging, and external service integrations, proactively flagging and addressing systemic risks.\nDesign and implement observability strategiesusingOpenTelemetry, Prometheus, and LangSmithacross the full request lifecycle (inbound channel → intent worker → NATS → agent worker → external service), with comprehensive distributed tracing and SLA target definitions for each agent worker and external service dependency.\nBuild operational resilience- implement NATS messaging failure recovery patterns, manage platform uptime, and drive SLA adherence for Chat/Portal real-time latency, Email throughput, and external service availability.\nLead code reviews and enforce coding standards- including Pydantic validation patterns, LangChain agent design, async FastAPI endpoints, and security-first practices - ensuring quality across the full Python/FastAPI codebase.\nPartner with cybersecurity teamsto address security assessments and implement solutions for findings including API Key Auth, mTLS, OAuth2, PCI-DSS log redaction, and input guardrails (CSAM, injection, SSRF, abuse filtering); teach security-first development practices across the team.\nMentor and develop engineersthrough hands-on pair programming, code reviews, and technical guidance on LangChain agent patterns, MCP protocol implementation, and RAG pipeline optimization; empower team members to own agent worker design and individual microservice delivery.\nRemain current in skillsby continuously evaluating emerging agentic AI frameworks, MCP protocol evolution, and RAG advancements, and investing in team capability growth across the VisaAssist architecture and NATS pub/sub patterns.\nForecast labor and support fiscal planning- project labor needs for agent worker development, infrastructure capacity, and LLM/GenAI API cost projections; support workforce planning during QBR accounting for platform growth, operational burden, and technical debt reduction.\nKeep stakeholders and leadership informedof progress across epics, program delivery milestones, and overall platform health for the VisaAssist agent ecosystem.\nVisa requires at least 3 days in office, expectations of these days will be confirmed by your Hiring Manager.\nQualifications\nBasic Qualifications:\n11-15 years' work experience of work experience with a Bachelor's Degree or with an Advanced Degree (e.g. Masters/MBA/JD/MD) or at least 3 years of work experience with a PhD\nExperience in Java EE technologies, Open-Source frameworks including Spring, React, JavaScript, HTML5, and Web Services (REST/RPC).\nExperience on microservices, containerization, and ability to quickly build and drive team to support future systems.\nExperience evaluating business requirements and translating them into technical design documents.\nExperience in Design Patterns and data modelling.\nExperience in Kafka and other No-SQL databases.\nSolid understanding and experience working with Database systems like MySQL and MSSQL.\nExperience working on application servers like Apache Tomcat, OS platforms like UNIX, Windows, and Linux.\nExperience with build automation tools including Maven/Gradle/Jenkins/Grunt.\nExposure and good knowledge on web application security.\nExperience in version control tools: BitBucket, Git or similar.\nPreferred Qualifications:\nProgramming Languages:Expert-level Python development including async/await architectures, high-performance API design (FastAPI), advanced type systems (Pydantic v2), and serialization optimization (orjson).
