Overview:

You’ll build the infrastructure and workflows that power systematic and semi-systematic trading at scale. Sitting at the intersection of research and engineering, this role enables large-scale experimentation, high-fidelity backtesting, and data-driven strategy development. 

You’ll partner closely with traders and researchers to turn ideas into measurable experiments—designing robust backtests, iterating quickly, and uncovering signal in complex datasets. The systems you build will be critical to exploring new trading strategies, refining execution logic, and supporting advanced techniques including machine learning. 

This is a highly experimental environment where progress depends on speed, correctness, and the ability to ask—and answer—the right questions.
