Growth Data Scientist employed at Mercari to drive ML initiatives for business impact and user engagement.
Responsibilities
Drive ML-Powered Interventions: Design, build, and productionize models that predict user behavior (e.g., conversion, churn, and reactivation) to estimate incentive elasticity and incremental business impact.
Innovate Personalization Systems: Architect the shift toward dynamic incentive control, intelligent exposure, and highly personalized targeting at scale.
Own Business Outcomes: Take direct responsibility for marketing and incentive ROI, incremental GMV, and LTV uplift, utilizing model performance as a powerful lever for business success rather than just an end goal.
End-to-End Experimentation: Actively drive the ML lifecycle from experiment design and KPI definition to post-launch analysis and continuous iteration.
Cross-Functional Partnership: Collaborate tightly with Growth, Marketing, and Product teams to translate complex growth opportunities into scalable, ML-driven decision frameworks.
Build Reusable Growth ML Foundations: Develop shared frameworks for uplift modeling, elasticity estimation, and intervention optimization to accelerate the rollout of future growth initiatives.
Requirements
Strong interest in growth, marketing, and direct business impact, with a willingness to explicitly own business impact.
Proven experience applying machine learning to real, user-facing decisions and production environments.
Proficiency in Python and SQL; experience with ML frameworks (e.g., scikit-learn, XGBoost, LightGBM, TensorFlow, or PyTorch)
Experience with large-scale data processing tools (e.g., BigQuery, Spark, or equivalent)
Solid understanding of statistics, experimental design, and causal reasoning
Familiarity with ML deployment and monitoring in production systems
