Senior Software Engineer - BLPAPI Experience
Bloomberg
Who we are:
Bloomberg’s data underpins the world’s financial systems, and the Real-Time Data Distribution Platform delivers it to hundreds of thousands of enterprise customers and Bloomberg Terminal users. We’re building one of the largest data distribution infrastructures in the world—delivering trillions of data points every day, in real time. Clients rely on this information for trading, market analysis, portfolio and risk management, and more. Given the scale, speed, and critical nature of our product, we are always focused on scalability, performance, and reliability.
Our team:
The Bloomberg API, known as BLPAPI, is the gateway to our real-time data distribution platform. Our BLPAPI Core team in London and BLPAPI Features team in New York work together to develop and maintain the API that enables clients to build applications accessing vast amounts of global data.
Designed for performance and flexibility, the API is multi-threaded, asynchronous, and implemented in C++, Java, Python, and C#. This unique setup allows engineers to explore and leverage the strengths of multiple languages while developing deep expertise in their preferred one. Our work centers on solving complex distributed systems challenges while continuously expanding the API’s features to meet evolving client needs.
We collaborate closely with the Enterprise Data product team, gathering feedback directly from clients, as well as with internal partners across Bloomberg. While we take pride in delivering high-quality software with thorough testing, we’re looking to expand our focus on usability improvements and evolving the SDK to support new client workflows.
We’re now building a new BLPAPI Experience team in Frankfurt. The team’s mission is to create a smooth, observable, and efficient developer experience—enabling fast onboarding, actionable diagnostics, and self-service tools that help clients succeed with minimal friction. Key focus areas will include:
Designing and maintaining wrappers or helpers that abstract complex internal behaviors and simplify usage
Developing and maintaining client-facing documentation
Improving SDK visibility and debuggability
Building and maintaining developer tools such as testing frameworks and code generators
