Job description

• Engage with the business objectives behind key tasks: pricing for B2B/B2C, forecasting and optimization of financial and operational metrics, incident prioritization, and improving customer journey efficiency (revenue growth, cost savings, business impact).
• Drive ML projects end-to-end: from problem definition and formalization to modeling, piloting, and presenting results.
• Collaborate with data engineers to collect the necessary datasets and assess implementation feasibility.
• Work with analysts on A/B test design: defining metrics, splits, and interpreting results.
• Develop models (classic ML and DL, time series, uplift modeling), conduct error analysis and performance evaluation.
• Prepare models and code for transfer to production infrastructure (deployment and releases handled by the technical team).
• Take ownership of model quality, monitor key metrics, and collaborate with the team on degradation issues and improvement plans.
• 3+ years of experience as a Data Scientist.
• Proven experience with end-to-end ML projects (ability to oversee the entire process).
• Strong knowledge of classical machine learning techniques (feature engineering, classification, regression, boosting, etc.).
• Hands-on experience with uplift modeling and time series tasks (with real business applications).
• Experience working with business stakeholders and understanding optimization problems: pricing, B2C, LTV, retention, AB testing, and more.
• Proficient in Python for DS/ML (writing clean, readable code for models and experiments).
• Confident SQL user (able to build datasets, write joins, and perform data analysis).
• Nice to have: experience with MLflow/DVC, pipelines (Airflow or similar), anomaly detection/anti-fraud, deep learning (PyTorch/TensorFlow), and model monitoring.
