Staff Data Engineer

The Risk and Identity Solutions (RaIS) team provides risk management services for banks, merchants, and other payment networks. The Predictive Fraud Intelligence (PFI) team develops core AI/ML products within the Visa Protect suite, empowering clients to detect and prevent fraud throughout the payment lifecycle. The MLOps and Data Engineering team designs and operates the platforms, pipelines, and tooling that enable the core product teams to build, deploy, and iterate on models quickly. This group provides the scalable data foundations, model orchestration frameworks, and automated workflows required to keep fraud detection models continuously updated against emerging fraud schemes and new attack vectors.

We re looking for candidates who are passionate about building high performance data systems and who thrive on the challenge of working with petabyte scale datasets. If you have experience designing efficient, resilient pipelines optimizing distributed data processing and enabling real time insights from massive, complex data flows, we want to meet you. This role is an opportunity to apply deep data engineering and MLOps expertise to a mission critical domain empowering fraud detection models that protect the entire payment lifecycle.

This is a great opportunity to be part of a Data Engineering and MLOps team that is set out to scale and structure large scale data engineering and ML/AI that drives significant revenue for Visa. As a member of the Predictive Fraud Intelligence MLOps team based out of Bangalore, your role will involve

• Building and maintaining reliable data pipelines that deliver high quality data across the product lifecycle Product development to client support.
• Developing platforms that support rapid model experimentation, training, evaluation, versioning, and deployment.
• Creating automated monitoring systems for data drift, model performance, and operational health to ensure models stay accurate as fraud patterns evolve.
• Partnering closely with AI/ML researchers and product teams to reduce time from model concept to production.
• Ensuring compliance, security, and traceability across the full ML lifecycle to meet financial industry standards.
• Providing self service tooling and infrastructure that enables data scientists to iterate quickly while maintaining operational excellence.

You must be a hands-on expert able to navigate both data engineering and data science disciplines to build effective engineering solutions that support ML/AI models.

The position is based at Visas offices in Bangalore, India.

What success looks like

• You consistently design and deliver systems that scale to petabytes of data with high reliability, low latency, and efficient resource utilization.
• You provide the architectural direction for the platforms, influencing long term technical strategy and raising the engineering bar across the organization.
• You proactively identify gaps in data quality, platform capabilities, and system resilience, and lead cross team efforts to close them.
• You mentor engineers across multiple teams, shaping best practices in distributed systems, pipeline design, and machine learning operations.

This is a hybrid position. Expectation of days in the office will be confirmed by your Hiring Manager.
