• Partner closely with Product, Engineering, Operations, and company leadership to translate complex marketplace problems into clear scientific questions, measurable hypotheses, and scalable solutions.
• Lead applied science work across forecasting, experimentation, causal inference, marketplace measurement, matching, ranking, allocation, optimization, and quality modeling.
• Build and grow a high‑performing team, setting technical standards, mentoring scientists, and creating a strong culture of rigorous, practical, product‑oriented science.

Qualifications

• Strong technical depth in experimentation, causal inference, statistical modeling, forecasting, marketplace science, or product analytics.
• Experience with marketplace or platform problems, especially in supply‑demand dynamics, liquidity, matching, user behavior, trust, or quality.
• Experience leading algorithmic work such as matching, ranking, optimization, allocation, quality modeling, or decision systems.
• Comfortable setting technical direction, influencing product strategy, partnering with engineering, and communicating complex trade‑offs to senior stakeholders.
• Ability to grow into a formal people manager or operate as a people manager, with a track record of leading high‑impact applied science work.
