About the role

Key responsibilities & impact

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.

Requirements

What you’ll need

3–4 years of hands-on experience in a data science or applied ML role.
Strong command of classical ML algorithms - gradient boosting, random forests, SVMs, logistic regression, clustering, dimensionality reduction, etc.
scikit-learn, XGBoost, LightGBM, CatBoost. Proficiency with ML frameworks:
PyMC or PyMC-Marketing. Solid understanding of probabilistic modeling, Bayesian inference, and uncertainty quantification; working experience with
Python (pandas, NumPy, SciPy, matplotlib/seaborn/plotly, MLflow). High proficiency in
SQL skills - complex multi-table queries, window functions, performance optimization. Strong
Deep familiarity with model evaluation frameworks: cross-validation, calibration, AUC, RMSE, MAPE, lift/gain curves, and business-aligned metrics.
Experience with experiment design, A/B testing, and statistical hypothesis testing.
Comfortable working with cloud data warehouses (AWS Redshift, BigQuery, Snowflake) and standard ML experiment tracking tools (MLflow, W&B).
NICE TO HAVE: Exposure to survival modeling, causal inference, or marketing mix modeling (MMM).
Experience with time-series forecasting libraries (Prophet, statsmodels, sktime).
Prior work in fintech, PAYG, or emerging markets contexts.
Familiarity with MLOps pipelines and model deployment on AWS (SageMaker, Lambda, ECS).
B.Tech / B.E. / B.Sc. / M.Tech / M.Sc. in Computer Science, Statistics, Mathematics, Engineering, or a closely related quantitative discipline.
