  • Design and build the risk framework for emerging asset classes

  • Build tooling and infrastructure that make risk management scalable

  • Independently scope and drive large, ambiguous projects from specification through production, partnering closely with trading, engineering, and research

Qualifications

Required

  • A strong quantitative foundation (degree or equivalent experience in math, statistics, physics, engineering, computer science, or a related field) with demonstrated quant interest and aptitude, e.g., economic or financial modeling

  • Experience building and shipping production software, not solely research or analysis
