Job Description
As a Decision Scientist, you will be the expert on cause and effect within our logistics network. Your primary responsibility will be to answer the most critical strategic questions facing our business: "What should we do, and why?"

• Drive Experimentation: You will design, launch, and analyze complex experiments (A/B/n tests) to measure the precise impact of changes to our dispatching algorithms, rider incentives, and customer promises.
• Quantify Trade-offs: You will build economic and simulation models to quantify the intricate trade-offs between customer experience (e.g., delivery speed) and operational efficiency (e.g., cost per order), delivering clear ROI-based recommendations.
• Employ Advanced Causal Inference: When clean experiments aren't feasible, you will leverage a sophisticated toolkit of econometric and causal inference techniques to measure the impact of product launches and operational changes on our marketplace.
• Influence High-Level Strategy: You will partner directly with key stakeholders in Product, Engineering, Data (Science) and Operations to translate your findings into high-impact business strategy, fundamentally shaping the future of our dispatching roadmap.

• A strong grasp of econometrics and causal inference methods (e.g., Difference-in-Differences, Regression Discontinuity, Instrumental Variables).

• A robust statistical foundation, particularly in hypothesis testing and modeling.

• Technical Skills:

• Expert-level SQL.

• High proficiency in Python or R for data analysis and modeling, with experience using libraries such as Pandas, Statsmodels, SciPy, or causal inference packages (e.g., CausalML, DoWhy).

• Business Acumen: The ability to translate ambiguous business problems into a logical, analytical framework and to communicate complex scientific concepts to non-technical stakeholders.
