Senior Software Engineer – Open Banking

As a Senior Software Engineer in this team, you will:

• Build high-performance, scalable APIs integrating with both documented and undocumented banking interfaces.
• Co-develop integrations / features side-by-side with GenAI agents to dramatically increase speed-to-market and code quality.
• Operate in a true DevOps model—owning build, deploy, and maintain responsibilities in the cloud.
• Continuously experiment with Visa’s rich portfolio of Generative AI models (transformers, LLMs, GANs, VAEs, multimodal models) and cutting-edge AI tools for production and innovation.
• Deliver new features on a rapid cadence (every few days) with end-to-end accountability.

• Partner with GenAI agents for code generation, refactoring, and automated testing.
• Experiment in Visa’s AI sandbox, where multiple GenAI models and frameworks are available for employee-driven innovation.
• Apply Generative AI models to API integration challenges, anomaly detection, and intelligent automation.

• Build components integrating with banks’ APIs to aggregate and enrich consumer financial data.
• Handle high-load systems with stringent uptime requirements.
• Work with Visa’s Tink technologies stack: Java, Node.js, JavaScript, AWS, Kubernetes, Docker, SQL, Datadog and much more.

• Own end-to-end delivery: design, build, deploy, monitor, and maintain services in AWS/Kubernetes/Docker environments.
• Implement CI/CD pipelines, infrastructure-as-code, and automated observability using Datadog and related tooling.
• Participate in on-call rotations to ensure high availability and operational excellence.

• Coach junior engineers, especially in leveraging AI engineering assistants.
• Contribute to AI-first engineering culture—sharing learnings from model experimentation.

This is a hybrid position.
