Our data moves global financial markets – and conversations around that data are central to how markets are shaped. Our Community group builds the infrastructure responsible for delivering real-time communications between the 350k financial professionals on the Bloomberg Terminal. Our email (MSG) and instant message (IB) products deliver billions of messages across millions of chat rooms per day, including stock quotes, trade confirmations, breaking news alerts or help desk inquiries among others, forming one of the largest financial networks in the world and placing our team at the center of our universe! Our users rely on these products because of their real-time performance, extensive scale, ironclad security, tight integration with financial data and applications.

About the Infrastructure and Reliability Team:

Our users count on these products’ real-time performance, massive scale & reliability. Given the criticality of our products to the daily workflow of the financial community, and the scale at which they are used, our team is one of the most visible teams across Bloomberg. Our products are continuously evolving and have experienced more than 100% growth in usage over the last year, which means we must have very high standards for reliability, stability, and scalability, with a deep understanding of distributed systems.
What you’ll do:

  • Define standards & maintain libraries for monitoring, logging, distributed tracing, alarming, and provisioning across 100+ developers.
  • Build software to monitor the health of IB and MSG systems via black-box health testing frameworks and other approaches.

  • Establishing standards and building dashboards, libraries and tools for metric collection, visualization, and alarming.
  • Establishing procedures around scalability, failover, Service Level Objectives (SLOs), cluster provisioning, deployment strategies, etc. with the goal of improving the robustness of our infrastructure.

  • 4+ years working with an object-oriented programming language (C/C++, Python, Java, etc.).
  • A Degree in Computer Science, Engineering, Mathematics, similar field of study or equivalent work experience.
  • An understanding of Computer Science fundamentals such as data structures and algorithms.
  • Demonstrated experience designing and implementing large scale distributed systems.
