Requirements

• Academic background: Bachelor's degree or above in Statistics, Data Science, Computer Science, Applied Mathematics, Econometrics, or a related field.
• Strong theoretical foundation in statistics and experimentation: Exceptionally solid grounding in statistical inference, with a deep understanding of the underlying principles of A/B testing and statistical methods (e.g., hypothesis testing, confidence intervals, variance reduction). Familiarity with causal inference methods (PSM, DiD, Uplift Modeling, etc.) and their application logic in long-horizon or non-randomized intervention scenarios; ability to build systematic analytical frameworks.
• Technical and data capabilities: Proficiency in SQL, with the ability to efficiently process massive, high-frequency behavioral data and trading logs. Proficiency in Python or R for statistical modeling, simulation, and automated analysis scripting.
• Business acumen and systems thinking: Strong interest in and foundational understanding of securities trading, wealth management, or internet finance. Excellent abstraction skills and a holistic perspective, with a talent for distilling complex business scenarios into standardized systems.
• Soft skills: Excellent cross-team communication and project-driving capabilities, with the ability to collaborate effectively with product, engineering, and compliance teams to drive solutions to delivery. Strong self-motivation and resilience under pressure, combined with business and data sensitivity, and the ability to deliver consistently amid concurrent multitasking.
• Excellent English & Chinese listening, speaking, reading, and writing skills; ability to read English technical documentation and to communicate with external vendors in English for day-to-day and technical coordination.
