Hands-on experience building and deploying machine learning models in a production environment, fraud, risk, or financial services experience is a strong plus
Solid grounding in data science fundamentals: experimentation, statistical inference, model evaluation, and feature engineering
Proficiency in Python and SQL; comfort working across the full model development lifecycle
An investigative instinct, you enjoy digging into data to find patterns others miss
The ability to communicate technical findings clearly to non-technical stakeholders and translate insights into action
Comfort working in fast-paced, cross-functional teams with high ownership expectations
