Our product

Bloomberg’s API, known as “BLPAPI”, provides an interface for accessing various data sets to Enterprise customers around the world. Our team develops real-time services that will use Bloomberg's enterprise distribution infrastructure to provide these data sets using a request/response or publish/subscribe model. These services, which are a part of the Market Depth product suite, provide access to premium market data known as Market Depth in the financial industry. Market Depth represents a structured table (or “book”) of all open buy and sell orders on a trading venue that are competing for the best price available for a tradable financial asset. The responsibility of the Enterprise Market Depth team is to normalize, build, enrich and distribute these “books” to all interested parties in near-real-time. Our mission is to deliver high-quality, high-availability and low-latency market depth data to our customers for an exceptionally diverse set of markets. On days when the financial markets are very active, our systems can process over 100 billion market data events with peak periods of 8 million events per second.

Our customers

Our services are used by major investment banks, hedge funds, and even internal teams for their applications. The data we provide is crucial to their workflows, enabling them to perform sophisticated analytics, make trading decisions and manage risks efficiently. Our enterprise data systems make up part of one of the fastest growing areas of Bloomberg (Enterprise Real-time), and we work directly with clients on the cutting edge of financial technology. 

What's in it for you?

The ever-increasing throughput requirements, high availability, low latency and business agility needs of our services offer diverse challenges. We are conscious of the impact our code and architectural changes can have on our users, and we use an array of tools to measure the performance of our services. We are a small team with a key role in Bloomberg and your contributions can have a big impact on the product and our customers. Because we are part of a fast growing business, the suite of products is always expanding, which will give you the opportunity to manage and deliver new software. You will have an opportunity to make decisions on how best to solve problems by either building them from scratch, or leveraging an open source solution.
