We are looking for a Quantitative Analyst to become the mathematical backbone of our Trading Core and Risk Tech squads. In a high-frequency trading environment processing billions in volume, success is defined by precision.

In this role, you will design, backtest, and optimize the core mathematical models that drive our pricing engines, automated market-making algorithms, risk management frameworks (A/B/C-book optimization), and liquidation mechanics. You will sit at the intersection of advanced mathematics, data science, and high-performance software engineering, working directly with Core Product Managers and engineering teams to turn complex financial data into proprietary algorithmic advantages.

Responsibilities

Research, design, and prototype quantitative models for pricing, risk management, and market making

Build and maintain robust backtesting frameworks to validate the performance and safety of models before production deployment

Write clear, comprehensive mathematical and algorithmic specifications for Backend Engineers (Trading Core squads)

Cross functional with the R&D and Trading Ops teams

Conduct post-incident deep dives (e.g., after major market gaps or liquidations) to identify algorithm performance gaps and optimize them

Exceptional knowledge of probability theory, stochastic calculus, time-series analysis, and financial mathematics

Advanced proficiency in Python (NumPy, Pandas, SciPy, SK-Learn, Statsmodels) for data analysis, modeling, and backtesting

Experience with Machine Learning

Deep understanding of market microstructure, order book dynamics, risk metrics (VaR, Expected Shortfall), and margin/liquidation mechanisms

SQL skills and experience working with large-scale historical market data (tick data, order logs)

Strong logical thinking, initiative, and well-developed communication skills

Will be a plus

Experience in CFD, Crypto CEX, Prop Trading Firm, or Hedge Fund

Degree (MSc or PhD preferred) in a highly quantitative field: Mathematics, Physics, Quantitative Finance, Statistics, or Computer Science

Understanding of Asset pricing models (e.g., Black-Scholes, local volatility models, Greeks management)

Knowledge of the MetaTrader platforms (MT4/MT5)

Experience with AI (Claude.io, Copilot, Codex)
