Quantitative Researcher — Event Signals

You will design, test, and productionize signals derived from news, research notes, filings, and social attention data. You will work across the full stack of a research idea: hypothesis, feature engineering, validation, and deployment. We expect strong empirical discipline and a bias toward falsifiable results.

You likely have

Demonstrated research output in quantitative finance, NLP, or an adjacent empirical field
Fluency in Python and comfort with large tabular data (ClickHouse, Arrow, Polars, etc.)
A portfolio of honest negative results alongside positive ones

Quantitative Researcher — Market Microstructure

You will study how events transmit into price at the minute and sub-minute scale — volume dynamics, order-flow imbalances, reaction asymmetries across market segments (SSE / SZSE / BSE). You will partner closely with the infrastructure team to ensure signals survive the journey from research to production.

You likely have

Hands-on experience with high-frequency or intraday data
Strong statistical intuition, especially around non-stationarity and survivorship
Comfort shipping research that runs, not just research that reports
