You will share responsibility for maintaining our pricing infrastructure and provide live operational support when necessary. You will also work with traders, researchers, and other engineers to develop our next-generation pricing platform.

This is a high-impact role, where you will frequently take input from senior leadership and work independently on large projects. It is not an easy role, but it is rewarding. On any given day, you might:

  • Deploy a hotfix for an issue you discovered at 8:30am before the market opens at 9:30am (US hours)
  • Prototype novel techniques for pricing and model execution leveraging open-source tools
  • Develop new features to productionize our next-generation platform
  • Creatively respond to hardware failures during market hours
  • Collaborate closely with researchers and traders to understand their needs and develop solutions that drive PnL


Rather than someone who already has specific knowledge, we're looking for someone with the aptitude and appetite to quickly develop new skills and put them into practice. We expect you to:

  • Have exceptional programming skills (systems programming experience required – C, C++, or Rust)
  • Know how computers work (think operating systems, networking, basic hardware-level knowledge)
  • Show demonstrated, deep interest in financial markets (no professional experience required)
  • Bridge the gap between trading and technology ("How can we design a maintainable solution to extract this signal from the market?" rather than "How can we patch this code to fulfill a short-term request?")
  • Be bold enough to question everything, but humble enough to admit when you're wrong
  • Communicate clearly in English
  • Remain calm under pressure, and quickly solve problems in the face of uncertainty


We're proud to employ some of the leading talent in the industry, and we work to ensure our employees enjoy a high quality-of-life.


All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, age, national origin, or protected veteran status, and will not be discriminated against on the basis of disability.
