Senior Software Engineer - Hadoop Infrastructure

The Team

Bloomberg runs on data! It's our business and our product. Financial institutions need timely, accurate data to capture opportunities and evaluate risk in fast-moving markets, from the biggest banks to elite hedge funds.

Bloomberg's application teams face complex challenges - large-scale data storage, low-latency retrievals, high-volume requests, and high availability over a distributed computing and storage environment. 

Hadoop Infrastructure's mission is to provide a multi-tenant, observable, and highly available infrastructure backed by the open-source Apache Hadoop platform (HDFS, HBase, YARN, etc.) to support large-scale data applications across Bloomberg. The Hadoop Infrastructure team manages clusters that handle 10s of PB of storage spread across 1000s of servers running 100s of billions of requests per day and running 10s of thousands of jobs hitting 100s of thousands of tables every day. We also provide standard methodologies and domain expertise on Hadoop services to applications across various product domains at Bloomberg.
