Data Scientist

Job location: Remote About the role: We are looking for a skilled Data Scientist who can translate complex datasets into actionable business insights through rigorous statistical analysis and machine learning. The ideal candidate combines strong foundational knowledge of classical ML with a solid grasp of probabilistic and Bayesian modeling, and can operate effectively across the full spectrum from data exploration to production-ready model delivery. 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. You might be a strong candidate if you have/are REQUIRED SKILLS & QUALIFICATIONS 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, [link removed] with ML frameworks: PyMC or [link removed] 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 [link removed] 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). EDUCATION [link removed] / B.E. / [link removed]. / [link removed] / [link removed]. in Computer Science, Statistics, Mathematics, Engineering, or a closely related quantitative discipline.
