Hiring Manager
Ajeet (AJ) Kumar
Responsibilities
Lead the design, development, testing, and global deployment of large-scale time series forecasting models (including Regression models and state of the art time series specific models for example N-BEAST, PatchTST) to support complex retail and e-commerce hierarchies. Introduce causal modeling approaches to conduct impact analysis for future forecast
Continuously enhance forecasting strategies by incorporating advanced machine learning architectures, including RNNs (sequence modeling), CNNs (temporal feature extraction), and Attention-based mechanisms to improve accuracy, scalability, and robustness in time series forecasting
Advance causal modeling frameworks to quantify event impacts and integrate causal insights into forward-looking forecasts
Build and maintain experimentation pipelines (A/B testing, quasi-experiments, multi-armed bandits) for evaluating causal impacts of interventions
Mentor junior scientists, review research and production code, and ensure reproducibility and scalability in pipelines
Collaborate with engineering to implement forecasting + optimization systems in production (Airflow, Astronomer, Spark/Ray)
Act as technical lead on multiple projects, balancing research rigor with business delivery
Qualification
Required
Strong foundation in Time Series Forecasting, Causal Inference, Statistical Analysis, and advanced Machine Learning methods
Hands-on experience with a wide range of ML techniques, with a deep understanding of their advantages and limitations across different scenarios
Ability to integrate statistical expertise with machine learning methods to maximize the value and interpretability of ML solutions
Proficiency in Python, SQL, PyTorch, Spark/Ray, and stats/econometrics libraries
Experience deploying ML systems at scale on cloud platforms (GCP/Azure)
Preferred
Publications and open-source contributions spanning the full spectrum of modern Machine Learning, from Statistical Learning (e.g., Bayesian modeling, causal inference, high-dimensional statistical methods) to Deep Learning (e.g., convolutional and transformer-based architectures) and Reinforcement Learning (e.g., dynamic programming, policy gradient methods)
Exposure to ML observability: drift detection, retraining triggers, and causality-informed monitoring
Background in retail, e-commerce, or operations analytics
