Who we are:

The way our clients consume data has changed. Bloomberg's application teams face complex challenges of large-scale data storage, low-latency retrievals, high-volume requests, and availability over a distributed environment. We create standardized solutions to these problems by building core services and technology frameworks for enterprise-wide use.

Our team:

The Bloomberg High Availability Timeseries Store (BHATS) ecosystem is a consumer timeseries/time-related data store supporting storage of multi-temporal data sets and retrievals against multiple-temporal dimensions. This platform serves the needs for date-specific data sets with point-in-time, as-reported use cases and timeframes (anywhere from by-the-minute to hourly to quarterly). Our mission is to enable content owners and application teams to acquire, transform, store, and serve business and financial data, expediting go to market for our clients.

We provide BHATS offering in two forms:

  • BHATS as a standalone data store where application teams own, manage, and monitor the on-boarding and retrieval of their data through well-defined public interfaces
  • Managed BHATS platform where application teams can onboard their datasets through a standardized dataset configuration dataflow mechanism (BHDS) and execute retrievals through well-defined interfaces via Native APIs and/or unified timeseries analytic interop as well as general purpose data field services

As an experienced Java developer, we’ll trust you to:

  • Help us refresh and evolve many facets of our data and analytics infrastructure using existing Bloomberg technologies such as the BAS Java/BAS Reactor framework, as well as a new Kafka-based infrastructure to support the microservices which comprise business logic processing.
  • Influence core BHATS ingestion, retrieval, and bulk operations workflows as well as architectural decisions.
  • Design and develop systems that meet our latency, volume, storage, and scale expectations.
  • Integrate with other data sources like the Bloomberg Data Services (BBDS) platform, relational data stores (including MySQL and Postgres) and client or third-party application data feeds for ingestion purposes. Integrate with Blomberg specific retrieval mechanisms as well as an analytics and metadata-driven Bloomberg Query Language (BQL) engine.

What’s in it for you:

Many of Bloomberg's timeseries data workflows will eventually be clients/users of the BHATS ecosystem. This means:

  • You’ll gain exposure to our financial data sets, non-financial data sets as well as client-specific ones and how they're used across our client workflows while ensuring we build high performance, low-latency, and scalable software for these core infrastructure initiatives.
  • Much of these applications are being built on top of open source technologies, so there are plenty of avenues to innovate and contribute to the open source community!

You’ll need to have:

  • 5+ years of experience programming in Java including Java 8
  • Experience enhancing and maintaining high throughout, low-latency systems in a mission-critical, test-driven production environment.
  • BA, BS, MS, PhD in Computer Science, Engineering or related technology field
  • Experience in software instrumentation for monitoring and observability

We’d love to see:

  • 3+ years with distributed message and/or stream-based processing
  • 3+ years of experience with NoSQL data stores (preferably HBase or Cassandra)
  • Experience with Spark, Kafka, Redis, Zookeeper or Flink
  • Experience with working with structured (Parquet, Avro, Orc, Protocol Buffers) data
  • C++ or Python development experience is a plus
