Job description

Senior Software Engineer, Treasury (Ruby/Python)Senior Software Engineer, Treasury (Ruby/Python)

Job Location Chicago

Employment type Regular

Department Technology

Targeted Start Date Immediate

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.

DRW has an opening for a Senior Software Engineer on its Treasury Development team. Treasury developers build and operate systems that support secured financing, margin and collateral management, and cash and liquidity management across the firm. The team is small and collaborative — you’ll work directly with Treasury business partners and enjoy building meaningful products from day one.

At DRW we strive for an environment where technologists are free to pursue solutions to the problems of the business free from arbitrary management constraints and supported by excellent technical resources. All development teams at DRW believe in rapid deployment and feedback, automated testing, and cohesive, transparent, lightly-coupled service architectures. We ship on Kubernetes with modern CI/CD.

Responsibilities:

  • Designing, building, and testing full-stack applications (APIs through UI) used by Treasury and related business partners
  • Partnering with Treasury staff 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); we don’t hand systems off to a separate ops team
  • Working across greenfield systems and existing codebases
  • Building and improving tooling and processes around CI/CD, containers, and Kubernetes / internal cloud
  • Collaborating with other software teams, IT, trading desks, and business units
  • Mentoring and raising the bar for engineering practice on a mid-sized team
  • Learning and championing useful new technologies where they fit
  • We are looking for strong senior generalists. Familiarity with the below helps on Treasury systems; none of it is a hard gate.
  • Payments and/or treasury systems (especially helpful)
  • Trading or general fintech
  • Full-stack development in Python (FastAPI) and/or Ruby (Rails)
  • Strong relational data modeling fundamentals
  • GitOps and Kubernetes

Candidates should have strong initiative and proven experience independently driving projects to completion. We work from high-level requirements and value engineers who dig into the business to build the right thing.

The annual base salary range for this position is $175,000 to $275,000 depending on the candidate’s experience, qualifications, and relevant skill set. The position is also eligible for an annual discretionary bonus. In addition, DRW offers a comprehensive suite of employee benefits including group medical, pharmacy, dental and vision insurance, 401k (with discretionary employer match), short and long-term disability, life and AD&D insurance, health savings accounts, and flexible spending accounts.
