The Opportunity: 

We are seeking a seasoned Fullstack Senior Staff Software Engineer with experience building GenAI-enabled applications. We're looking for someone who is both a hands-on full-stack engineer and a team leader capable of designing, developing, and deploying GenAI‑powered applications. You will mentor an engineering team while delivering scalable AI systems that integrate with Visa’s product ecosystem, developer platforms, and internal operational tools.

This role blends architecture, leadership, full-stack development, cloud engineering, and GenAI frameworks.  As a Visa Senior Staff Software Engineer (internal title: Sr. Consultant), you will be an integral part of a multi-functional development team inventing, designing, building, and testing software products that reach a truly global customer base. While building components of powerful payment technology, you will get to see your efforts shaping the digital future of monetary transactions.   

The Work itself: 

• Global Operations holds the responsibility of ensuring Visa’s diverse portfolio of commercial services are performing optimally, meeting stringent availability targets and exceeding our clients’ expectations.  
• By architecting automation and GenAI into our operational DNA, and deeply embedding AIOps into our strategic foundation, Global Operations, the engine room of production operations, is well positioned to think big, act quickly and innovate with intention. 
• Working with highly integrated, high-throughput systems, an equally high importance must be placed on robust observability, intelligent event detection and incident management.  
• Global Operations sets the operational standards to support the business demands of today and the operational needs of tomorrow as technologies continue to evolve and adjust the way we work to support the business.  
• Through blame free post mortems, intellectual curiosity and problem solving we turn reactive into proactive and create an environment that provides the support and mentorship for our team members to learn and grow.
