We’re looking for a Data Scientist to join our Risk Data Science team. In this role, you will be instrumental in analyzing complex datasets to generate insights that drive critical business decisions, specifically within credit risk, fraud prevention, and churn reduction. You will work cross‑functionally to design, build, and deploy data‑driven strategies that ensure Clara continues to scale securely and efficiently.

• Build and deploy predictive models: Design, develop, and monitor machine learning models using Databricks, MLflow, scikit‑learn, and PyTorch. Follow the CRISP‑DM methodology to ensure rigorous modeling standards from conception to production.
• Ensure data quality and integrity: Clean and transform raw data to ensure it is suitable for analysis, apply data quality checks, and maintain validation rules.
• Innovate and automate: Continuously monitor model performance and data drift while staying updated on advancements in AWS cloud infrastructure and statistical methods to refine our analytical approaches.

We’re looking for someone who meets the minimum requirements to be considered for the role. The preferred qualifications are a bonus, not a requirement.
