Data Scientist

Kempuri Data Science team focuses on transforming the largest organizations on the market using machine learning and advanced analytics. Projects involve building predictive and prescriptive engines (Causal ML), as well as automation using GenAI. Example projects includes: risk modeling, propensity/uplift analysis, churn forecasting, and demand forecasting. We are looking for individuals who have strong Python programming skills and the ability to communicate business conclusions, identify business needs, and then translate them into quantitative language.

Work is usually done in iterations that allow for quick and effective assessment of work results and their impact on the business process. Results are either integrated with dedicated applications or incorporated to data orchestration.

• Competitive salary package, reflective of experience and qualifications
• Opportunity to work remotely, supporting work-life balance
• Comprehensive benefits, including health insurance and a sports membership card
• Exposure to cutting-edge credit risk modelling technologies and regulatory frameworks
• Collaborative environment that encourages knowledge sharing and innovation
• Working on comprehensive implementations of models and analyses using ML across the full life cycle: Evangelization, Use Case Hunting, PoC, MVP, Productionization, Industrialization, Maintenance.
• Defining the analytical paradigm: how to translate model output into business decisions. Contributing not only to modelling but also results consumption by business / end users.
• Analysis and interpretation of model results, goodness of fit, and monitoring.
• Consulting on analytical use cases and their business impact.
• Preparing conclusions and simulations regarding the impact of ML use cases on business processes: estimating ROI, Uplift, Success Criteria.
