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. DRW is a place of high expectations, integrity, innovation and a willingness to challenge consensus.

UP (Unified Platform) consolidates data and technologies into a comprehensive solution, accelerating time to market. Optimizing decision-making and research, our platform simplifies implementing new ideas, enhancing our competitive edge. We work from high-level requirements where programmers are expected to gain an intimate understanding of the business. We strive for an environment where developers have the autonomy to pursue business solutions without arbitrary management constraints. We are a group of polyglots and technologists always seeking to find the right tool for each problem. Broadly, the development teams at DRW believe in rapid deployment and feedback, automated testing, and cohesive, transparent, lightly coupled service architectures.

DRW has openings forSenior Software Engineers on its Treasury and Reference Data development teams. These teams build and operate systems the firm depends on for financing, liquidity, and the instrument data that underpins trading and post-trade workflows. The teams are small and collaborative — you’ll work directly with business partners and enjoy building meaningful products from day one.

These openings sit on two related teams:

• Treasury — builds systems that support position financing, margin and collateral management, and cash and liquidity management across the firm.
• Reference Data — owns the data platform that stores and distributes instrument and related reference data used across research, trading, and post-trade workflows.

We hire through a single interview pipeline and match candidates to the team and problems that fit best as we learn more about each person’s current skills and long-term development goals.

Responsibilities:

• Designing, building, and testing systems used across the firm — services, data products, and the UIs that sit on them
• Collaborating with business partners to turn ambiguous business problems into clear technical plans and shipped software
• Owning software end-to-end after it ships — we run what we build (deploy, operate, on-call)
• Working across greenfield systems and existing codebases
• Building and improving tooling and processes around CI/CD, containers, and Kubernetes / internal cloud
• Mentoring and raising the bar for engineering practice
• Learning and championing useful new technologies where they fit

We are looking for strong senior generalists. Experience in the following areas is helpful:

• Full-stack development in Java, Python (FastAPI), and/or Ruby (Rails)
• Strong relational data modeling fundamentals
• GitOps and Kubernetes

Though prior domain experience is not required, relevant background can help place a candidate on a particular team:

• Payments and/or treasury systems (Treasury)
• Vendor/exchange data processing and/or data taxonomy (Reference Data)
