Job description

Job Description

Visa’s Technology Organization is a community of problem solvers and innovators, reshaping the future of commerce. We operate one of the world’s most advanced payment processing networks, enabling secure, reliable, and scalable transactions across millions of merchants, financial institutions, and consumers globally.

Our teams build and operate complex distributed systems at massive scale, solving challenges across payment flows, real‑time data processing, cybersecurity, and next‑generation digital platforms.

Within this, Value Added Services (VAS) – Digital Marketing is a key growth area for Visa, focused on building differentiated, data‑driven solutions that extend the value of the Visa network beyond payments.

About The Team

You will join a high‑performing engineering team building GenAI‑powered platforms and applications that enable innovation across Visa’s technology ecosystem.

Team Focus

• Developing intelligent, AI‑driven applications powered by large language models
• Integrating generative AI capabilities into enterprise platforms and workflows
• Building scalable systems that combine AI, data, and distributed architectures
• Enabling automation, developer productivity, and intelligent decision‑making

While these capabilities rely on strong data foundations, the primary focus is on applying AI and generative AI to solve real‑world business problems at scale, with enterprise‑grade security and reliability.

Job Summary

Staff Data Engineers are expert problem‑solvers, builders, and technical leaders who design and evolve platforms powering next‑generation AI and data‑driven applications. In this role, you will work extensively hands‑on with code, data, and modern technologies to deliver secure, scalable, and high‑performance systems that drive business outcomes.

You will play a key role in developing GenAI‑powered applications and platforms, including integrating with leading large language models such as OpenAI and Anthropic, and enabling their safe, scalable, and efficient use in enterprise environments.

You will independently understand data ecosystems, system design patterns, and security, privacy, and governance requirements, applying this knowledge to design robust and production‑ready solutions. You will translate complex business requirements into scalable architectures and guide implementation across the team.

This role requires strong expertise across backend engineering, data platforms, microservices, and real‑time distributed systems, along with the ability to influence engineering practices and drive high standards across teams.

All roles require digital fluency, including hands‑on experience or familiarity with Generative AI tools (e.g., Claude Code, Cline, Codex, and GitHub Copilot) to enhance developer productivity and enable intelligent engineering workflows.

Key Responsibilities

• Act as a key technical contributor in stakeholder discussions to clarify requirements and drive architecture and design decisions
• Design and deliver scalable, resilient platforms and services supporting AI/GenAI applications and data‑driven systems
• Translate functional requirements into end‑to‑end system architectures, leveraging established design patterns
• Build and integrate applications with large language model providers such as OpenAI and Anthropic
• Design and implement GenAI workflows, including prompt orchestration, context handling, and system integration layers
• Lead development of microservices, APIs, and platform components supporting distributed systems
• Build and optimize real‑time data streaming and event‑driven architectures for high‑throughput applications
• Implement extensible, maintainable, and reusable code following best practices, security standards, and coding guidelines
• Take end‑to‑end ownership of data products, platform components, or services, including reliability, scalability, and maintainability
• Drive code reviews, mentor engineers, and guide teams on system design, coding practices, and performance optimization
• Build tools and automation to improve data processing, deployment, monitoring, and platform operations
• Ensure adherence to data management principles, governance, security, and compliance requirements
• Identify and address technical debt, and continuously improve system design and performance
• Lead troubleshooting of complex issues across distributed systems and drive root‑cause resolution
• Support platform upgrades, scaling initiatives, and security remediation activities

Visa requires at least 3 days in office, expectations of these days will be confirmed by your Hiring Manager.
