About the role
Develop fair-value, spread, and fill-probability models, research market-making strategies, and build realistic backtests that account for trading costs and execution conditions. Collaborate with engineering to deploy strategies and ensure data and trading signals are reliable and correctly used. Candidates need at least two years of hands-on systematic trading experience and a background in a quantitative field, along with knowledge of market microstructure, predictive modeling, and quoting under inventory and adverse-selection risk. They should be able to build production-grade systems, use AI tools effectively, communicate clearly in English, and take ownership in a fast-paced, ambiguous environment.
