Requirements

  • Strong academic or professional background in Applied Mathematics, Statistics, Computer Science, Physics, Finance, or Quantitative Trading.

  • Deep understanding of market microstructure, high-frequency trading systems, probability, optimisation, and time-series analysis.

  • Proficiency in one or more programming languages commonly used in quantitative and HFT environments (Python, C++, Julia, R, or Rust).

  • Experience with simulation systems, trading infrastructure, latency optimization, or machine learning models is a strong plus.

  • Excellent analytical reasoning, communication, and collaboration skills.

  • Ability to commit to 20–30 hours per week, including the required synchronous collaboration periods.

Why Join

  • Collaborate directly with a world-class AI research lab to train and improve models that simulate both traditional and high-frequency trading dynamics.

  • Play a key role in shaping how AI systems understand and execute quantitative trading strategies in fast-moving, high-volume market conditions.

  • Enjoy schedule flexibility — choose your own 4-hour collaboration windows and manage your 20–30 hour work week around them.

  • Be engaged as an hourly contractor through Mercor, giving you autonomy over your time while contributing to high-impact AI and finance projects.

  • Work with elite researchers, traders, and engineers advancing the frontier of algorithmic intelligence, market prediction, and execution optimization.
