Data Analytical Engineer, Payment Data Intelligence - USDS

Responsibilities

About the Team:
The Global Payment team of U.S. Data Security department of Tik Tok provides payment solutions - including payment acquisitions, disbursements, transaction monitoring, payment method management, foreign exchange conversion, accounting, reconciliations, and so on - to ensure that users have a smooth and secure payment experience on Tik Tok platform.

The Payment Data Intelligence team is responsible for providing data driven intelligence to empower payment business growth, optimize payment processes and improve customer experience. We're looking for a highly skilled and motivated Data Analytical Engineer to join our team. The ideal candidate will be responsible for designing, building, and maintaining the scalable data infrastructure and ETL/ELT pipelines necessary to transform complex raw payment data into reliable, high-quality, and actionable datasets.

This role is critical in driving strategic decision‑making and optimizing our payment operations, fraud detection, and financial reporting.

On-site presence across teams allows the company to operate with greater speed, alignment, and agility — especially in areas like real‑time decision‑making, team development, and integrated execution. As such, the company is shifting from a hybrid work model to a fully in‑person schedule. The specific requirements may vary from team to team.

• Design, build, and optimize robust, scalable data models and ETL/ELT pipelines to ingest, process, and transform massive volumes of payment transaction data from various data sources (RDS, MQ, 3rd Party etc).
• Manage and maintain our data warehouse environment and data lake infrastructure, ensuring high performance, availability, and security.
• Implement automated data quality checks, monitoring, and validation processes to ensure the accuracy, completeness, and consistency of all payment intelligence datasets.
• Tune data pipelines and queries for maximum performance and cost efficiency, especially for real‑time and near real‑time data flows.
• Work closely with Data Scientists, Data Analysts, Product Managers, and solution teams to understand their data requirements and deliver custom data solutions that power reports, dashboards, and analytical models.
• Evaluate and implement new technologies and tools to improve data engineering efficiency and the overall data ecosystem.
• Create and maintain comprehensive documentation for data models, architecture, and ETL/ELT processes.
