What you'll do...

What you’ll do

+ **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.

What you’ll bring

+ 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).

Great to have

+ 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.
