Feature Engineering: Perform in-depth feature engineering, incorporating both technical and domain-specific nuances to enhance model performance by creating features for various horizontal use cases like promotion, seasonality, and vertical-specific features (shelf life for Fresh, color/size for Fashion etc.)

Data Patching Algorithms: Detect, Design, and Implement algorithms for missing, anomalous and irrelevant data.

Supervised and Unsupervised problems: Solve non-forecasting related data science problems involving classification, regression, and clustering within in-stock domain (Ex: likelihood of new selection sales potential, developing product attribute vectors, price elasticity, complements/substitute items etc.)

Cross-functional Collaboration: Diligently work with up/downstream product, business, finance, and product analytics teams to prioritize features and integrate data science solutions effectively.

Model Explainability and Debugging: Provide deep insights into model design/predictions and pinpoint error analysis to resolve fundamental flaws.

Improving Model Lifecycle: Enhance data quality, visibility, and transparency in model inputs, institutionalize processes for validating/certifying model accuracy and integrate deep analytics into model operations to ensure ongoing refinement and robustness.

Qualifications

Advanced degree (Ph.D. or Master's) in Data Science, Computer Science, Statistics, Mathematics, or a related field.

10+ years of data science or related field experience in SCM domain with proven experience in building highly analytical ML models from scratch having a focus on scalability and performance.
