Junior Trader jobs in Singapore

Mercor is hiring Quantitative Traders on behalf of a leading AI Lab building the next generation of intelligent systems for algorithmic and high-frequency trading (HFT). This is a unique opportunity to collaborate with world‑class AI researchers and engineers, applying your trading and quantitative expertise to train, evaluate, and refine cutting‑edge AI models for real‑world, high‑speed market applications.

• Collaborate with AI researchers to design, train, and validate trading algorithms and quantitative models, including high‑frequency trading strategies.
• Apply advanced mathematical, statistical, and computational methods to improve model stability, execution accuracy, latency performance, and market adaptability.
• Evaluate and refine algorithmic trading frameworks to ensure robustness and profitability across multiple asset classes, exchanges, and time horizons.
• Contribute to the training and fine‑tuning of AI systems, ensuring they capture realistic market dynamics, order book behavior, and risk‑management strategies specific to high‑frequency environments.
• Participate in synchronous collaboration sessions (4‑hour windows, 2–3 times per week) to review trading simulations, debug models, and exchange quantitative and technical insights.

• 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, optimization, 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.

• 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.
• Join a global network of experts driving the evolution of financial AI through quantitative innovation, speed, and precision.
