Senior Quant / Data Scientist for Trading Strategy

We are seeking a Senior Quant / Data Scientist to audit and replace the mathematical and statistical model (the Alpha) of an existing, fully functional crypto spot trading bot on Binance using Python. Our infrastructure, execution, risk engine, and out-of-sample backtest framework are 100 percent built and operational. However, the current model (RandomForest over technical indicators) suffers from severe overfitting (win rate drops from 90 percent in-sample to around 30 percent OOS) and tail dependency. We need a Quant specialist to design a new, robust statistical hypothesis with proven out-of-sample edge (Sharpe ratio over 1.5 and Profit Factor over 1.5 net of fees).
