DRW is a diversified trading firm with over 3 decades of experience bringing sophisticated technology and exceptional people together to operate in markets around the world.  We value autonomy and the ability to quickly pivot to capture opportunities, so we operate using our own capital and trading at our own risk.  

Headquartered in Chicago with offices throughout the U.S., Canada, Europe, and Asia, we trade a variety of asset classes including Fixed Income, ETFs, Equities, FX, Commodities and Energy across all major global markets. We have also leveraged our expertise and technology to expand into three non-traditional strategies: real estate, venture capital and cryptoassets.

We operate with respect, curiosity and open minds.  The people who thrive here share our belief that it's not just what we do that matters, it's how we do it.

The Pricing and Derived Data team is a domain engineering team in the Unified Platform organization, and is responsible for building and maintaining services used to generate prices and manage derived data for all traded products and products used for pricing purposes. We do so by building systems to catalog, ingest, store, and disseminate derived data, thereby ensuring high availability and coherence through the creation of robust services that support both intraday and end-of-day trade data. 

We are looking for an outstanding Software Engineer with diverse technical and interpersonal skills to join us in the next step of our development as we significantly expand our technical capabilities, enabling us to have an even greater impact across the firm.
