Passive investment continues to reshape global markets, and Indices are at the heart of this transformation. At Bloomberg we are proud to be a key player in this space, powering some of the most innovative and widely recognized indices across all asset classes with billions of dollars linked to them globally. As Bloomberg Indices expand our presence in the Equity Index market – using the strength of Bloomberg’s data and research heritage to rapidly grow in an established space – the robustness, scale and accuracy of our platforms are critical to our success.

The Derived Data team sits at the core of this effort. Our systems underpin every Equity Index calculation across Bloomberg, supporting benchmark, factor, thematic, custom and ESG strategies. In Equities, we work with corporate action impacts, forward projections of portfolios and metadata classification – supporting multiple methodologies to cover our product range. We also work across asset classes, providing orchestration and workflow for Commodities, FX, Rates, Futures, Options, Swaps and Crypto. We build out constituent data calculations, performant APIs, validation tooling, regression test automation and operational UIs whilst partnering with our ambitious Product and Operations teams.

We are seeking an experienced senior engineer who operates as a technical leader through complex initiatives. You will act as a bridge between Product, Operations and Engineering — translating financial methodologies and operational processes into robust domain models and scalable C#/.NET systems in an MQ-driven architecture. You will help shape architectural direction and domain design in an environment of significant growth, increasing methodological sophistication, and risk reduction – refactoring for substantial extensibility and performance gains. You will work with multiple stakeholders to drive nuanced cross-team projects to completion and continually evolve and modernize our platform for long-term performance, scalability and flexibility. This is a business-critical role at the core of Bloomberg’s Equity Index expansion.
