• Ensure AI systems comply with Visa's standards for security, reliability, performance, monitoring, and responsible AI governance.

Data Engineering & Pipeline Development:

• Build and optimize scalable data pipelines, ETL/ELT workflows, and distributed processing systems to support AI/ML and analytics use cases.
• Develop high?quality data models, transformations, and feature pipelines for production ML systems.
• Integrate structured and unstructured data sources from multiple internal and external systems into enterprise data platforms.
• Implement data quality, lineage, observability, audit logging, and metadata management for mission?critical datasets.

MLOps & Platform Engineering:

• Develop end?to?end ML pipelines including model training, evaluation, deployment, and monitoring using modern MLOps frameworks.
• Implement CI/CD workflows, automated testing, feature stores, experiment tracking, and scalable serving layers.
• Build containerized, cloud?native AI services using Docker, Kubernetes, and serverless components.
• Optimize performance across GPU workloads, vector retrieval systems, and large?scale batch/streaming jobs.

Technical Collaboration & Solution Delivery:

• Work closely with product owners, architects, data scientists, and engineering teams to translate business requirements into robust technical designs.
• Participate in architecture reviews, propose design improvements, and guide best practices in coding, data modeling, and ML lifecycle management.
• Deliver well?documented, maintainable, and secure production code.
• Troubleshoot complex AI, pipeline, and data performance issues in development, staging, and production environments.

This is a hybrid position. Expectation of days in office will be confirmed by your hiring manager.
