Our group:

The Data Services group is responsible for core data and analytics services which provides a single point of entry for Bloomberg Terminal and Enterprise applications to retrieve any kind of data available in Bloomberg. This includes multiple foundational services such as Data Gateway, Security ID Master, Metadata Infrastructure, Insights and Anomaly Detection System. These systems serve several hundred billion requests a day running on thousands of machines. With ever increasing data volumes and growth of Bloomberg’s Enterprise products, this footprint has been growing at a rapid pace (increasing 25% YoY).

Our team:

As part of a large initiative to organize our data using Semantic Technologies at Bloomberg, we are developing a triplestore, a type of graph database. The general idea behind Semantic Technologies is that all data can be modeled, serialized, and (logically) linked into a large Knowledge Graph, which can then be queried to answer questions like “How is my portfolio affected by the recent election results in Turkey?”.

The database will be used to store our semantic models and select datasets that are used by various engineering teams within the company. The team will be responsible for ensuring that information is correctly stored and made queryable on a highly available system with optimal runtime characteristics and reliability expected from any enterprise grade database. 

Our tech stack:

RDF4J, LMDB/RocksDB, Postgres, Java, Python, SPARQL, SHACL, Inferencers, R2RML, RDF

You’ll need to have:

4+ years of professional software development experience

A Degree in Computer Science, Engineering, Mathematics, similar field of study or equivalent work experience
