We are looking for a Quant Trader / Researcher to design, research, backtest, and trade systematic options strategies across NSE and BSE.

• Develop strategies around theta decay, gamma dynamics, expiry-day behaviour, pinning and volatility dislocations.
• Research implied volatility surfaces, term structure, skew, IV crush and realised-vs-implied volatility .
• Generate and evaluate signals using technical, derivatives and market-microstructure data.
• Work with datasets including Open Interest, PCR, OI changes, basis, price/volume and intraday data .
• Use statistical modelling, time-series analysis and machine learning for signal generation, regime detection and risk-reward estimation.
• Conduct rigorous backtesting across different market regimes, time periods and volatility conditions.
• Identify overfitting, look-ahead bias, survivorship bias and other research pitfalls.
• Translate validated research into live trading strategies in collaboration with trading and technology teams.
• Monitor live strategy performance, risk, exposures and P&L and recommend improvements where required.
• Continuously research new systematic opportunities and improve existing strategies.

Required Qualifications & Skills

• Strong understanding of Sharpe ratio, drawdown, Calmar ratio, hit rate, exposure and risk-adjusted returns .

• Comfortable working in a fast-paced, research-driven environment.
