Senior Data Engineer; Trade Surveillance

Role Overview

Effective Market Abuse Surveillance is highly dependent on data of multiple types and from many different sources. Trade Surveillance requires complete Trade and Pre‑Trade transactional data, Instrument and Client Reference Data and Market Data. Communications Surveillance requires ingestion of messages from multiple electronic platforms. This role will play a critical role in ensuring the reliability, scalability, and compliance of data pipelines that support surveillance systems across communications and trading activities, covering the above structured and unstructured data.

The role bridges engineering and operations, enabling robust data ingestion, transformation, and monitoring to meet regulatory and internal compliance requirements. The Data Ops Engineer will collaborate with upstream teams to ensure data completeness, accuracy, and timeliness, and that any data completeness or quality issues are visible. The role will also work on other Surveillance data initiatives such as persisting Surveillance Alerts in the firm’s data lake for analytics purposes.
