The role involves leading end-to-end projects across three main areas: growth (designing experiments to expand capital access responsibly), portfolio monitoring (building ML models to forecast repayment and measure servicing impact), and infrastructure (creating data pipelines and automation tools). Required qualifications include a bachelor's degree in Computer Science, Statistics, Mathematics, or related field, plus demonstrated statistical reasoning, business acumen, engineering skills, and the ability to work with stakeholders across the company. The team is composed of former data scientists from Robinhood, Uber, Airbnb, and other top tech companies, with a focus on first-principles thinking and craftsmanship. Compensation ranges from $200k–$235k for standard roles to $235k–$330k+ for senior/staff level, with equity, full benefits, and work-from-home flexibility. A standout detail: the co-founders were PhD data scientists at Robinhood, and the team explicitly values rigorous causal inference and the ability to ship ML models to production (XGBoost, LLMs, Streamlit apps).
