What you will be expected to do
KEY RESPONSIBILITIES
- Design, build, and evaluate classical machine learning models for business-critical use cases (classification, regression, ranking, anomaly detection, time-series forecasting).
- Apply probabilistic and Bayesian modeling techniques to quantify uncertainty and inform decision-making under uncertainty; leverage tools like PyMC and PyMC-Marketing for Bayesian workflows.
- Perform rigorous EDA, feature engineering, and data wrangling on large structured and semi-structured datasets using Python and SQL.
- Collaborate with data engineers and analytics engineers to source, clean, and validate data pipelines feeding ML workflows.
- Develop, track, and communicate model performance metrics; identify degradation signals and recommend retraining or improvement strategies.
- Translate business questions into well-framed statistical problems and present findings clearly to technical and non-technical stakeholders.
- Maintain clean, reproducible, and well-documented code and notebooks following team engineering standards.
