Ability to read and interact with C++ code.

Knowledge of distributed architectures, caching, or in-memory data handling.

Understanding of financial market concepts.

Education - Degree (or equivalent) in Computer Science, Engineering, Mathematics, Physics, or a related quantitative discipline.

Why Join Margo?
