Senior Data Engineer II - Real Time Data Engineering

In this role, you will design and build the foundations of Wise’s real-time liquidity observability and streaming data pipelines to support global treasury operations. You’ll work within the Treasury Global Liquidity team to enable dynamic, intraday capital positioning and high-visibility liquidity across currencies and nostro accounts. You will implement robust, scalable streaming architectures and collaborate with product, data science, and treasury teams to drive measurable impact. This is a high-ownership role with significant scope to shape the engineering approach and performance of critical liquidity systems.
