Bloomberg Tech Stack
Global financial data and news platform serving institutional markets
Bloomberg operates a sprawling financial data and news infrastructure built on Python, Java, C++, and Kafka, serving over 10,000 employees across engineering, data, sales, and editorial functions. The tech stack reflects a hybrid legacy-modern architecture: heavy use of Excel and VBA alongside React, GraphQL, and real-time streaming (Kafka, Redis), with active adoption of Apache Airflow and Databricks signaling a shift toward unified data orchestration. The hiring mix—weighted heavily toward senior engineers (375) and data specialists (105)—paired with active projects on data quality, retrieval-augmented generation, and kaas platform development, reveals an organization addressing foundational data governance and modernizing delivery mechanisms.
