Job Description

Staff Data Engineers are expert problem-solvers and builders who design, implement, and improve software applications and systems. In this role, engineers spend a significant portion of their time coding, working hands‑on with code, data, and modern tools-including AI-assisted development, cloud services, and automation frameworks-to deliver secure, scalable, and high-quality technology solutions that drive business outcomes in the fintech sector. They collaborate with cross-functional teams such as product managers, designers, data scientists, QA, operations, and compliance to translate business requirements into robust technical solutions, all while adhering to best practices, security standards, and regulatory requirements.

This is a hands‑on role requiring both deep data engineering expertise and the ability to work across legacy modernization and new platform innovation. You'll collaborate closely with the Agentic Engineer, ML teams, and business stakeholders to enable AI-driven insights and intelligent data orchestration.

Key Responsibilities

• Data Platform Modernization : Implement the transition from SQL Server data warehouse to the next-generation Hadoop/Databricks platform, ensuring performance, reliability, and minimal business disruption. Develop hybrid data pipelines that bridge legacy and modern ecosystems, enabling near real-time data access for analytics and AI applications. Optimize existing SQL Server models (facts, dimensions, indexes, stored procedures) and design modern equivalents in Hadoop and Spark environments. Define long‑term migration strategy, data partitioning, and retention policies aligned with Visa's data governance standards.
• Data Architecture & Engineering : Implement scalable, distributed data pipelines using Spark, Kafka, Airflow, and Delta Lake. Build robust ETL/ELT frameworks to process transactional, behavioral, and unstructured data at scale. Partner with the Agentic AI team to power RAG (Retrieval‑Augmented Generation) pipelines, vector database integrations and LLM data provisioning. Lead proof‑of‑concept (POC) initiatives to evaluate and integrate new data engineering technologies.
• Operational Excellence : Provide guidance to junior Engineers to maintain existing SQL Server‑based data warehouses, including database performance tuning, replication, encryption, and high‑availability (HA) solutions. Implement best practices in T‑SQL development, schema design, and stored procedure optimization. Perform proactive performance analysis, troubleshooting, and resolution of production issues in SQL Server and Hadoop clusters. Collaborate with DBA and application teams to ensure uptime within SLAs and compliance with Visa's data policies.
• Security, Governance & Compliance : Enforce standards for data quality, lineage, and governance across both legacy and modern platforms. Ensure full compliance with Visa's data privacy, encryption, and access control frameworks. Partner with InfoSec to embed data security principles into every phase of data lifecycle management.
• Leadership & Collaboration : Mentor and coach junior data engineers, fostering an environment of technical excellence and innovation. Collaborate cross‑functionally with product, ML, and platform engineering teams on architecture decisions and roadmap execution. Serve as a bridge between legacy enterprise data teams and next‑gen AI platform engineers, ensuring knowledge continuity and execution speed.

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