BlackRock Tech Stack

Global asset manager and investment platform provider serving millions of investors

Financial Services New York, NY 10,001+ employees Founded 1988 Public Company

BlackRock operates a multi-cloud infrastructure (AWS, GCP, Azure, OCI) layered across Java, Python, and C++ with heavy use of Oracle for financial operations and Aladdin as a core platform—a stack shaped for regulated, high-volume institutional finance. Active hiring across engineering, finance, and sales roles (522 in the last 30 days) combined with ongoing Aladdin implementation and new ETF product development suggests scaling the investment platform itself. Pain points around high-volume real-time data, process automation, and regulatory compliance align with the technical direction: Protocol Buffers and ISO 20022 adoption signal modernization of data exchange and payment standards.
