What you'll do

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.

Define and solve complex problems: Collaborate with cross-functional teams to identify business challenges, propose end-to-end solutions, and execute strategies that align with company objectives.
Drive data understanding and insights: Explore and interpret large datasets using SQL and Python to identify patterns, anomalies, and trends. You will translate these findings into actionable insights that support informed decision-making.
Build and deploy predictive models: Design, develop, and monitor machine learning models using Databricks, MLflow, scikit-learn, and PyTorch. You will follow the CRISP-DM methodology to ensure rigorous modeling standards from conception to production.
Ensure data quality and integrity: specific responsibilities include cleaning and transforming raw data to ensure it is suitable for analysis, applying data quality checks, and maintaining 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.

Clara’s Hybrid Policy

Claridians in a hybrid mode split their time between working from the office, talking to or visiting customers, or working from home. This hits a balance between bringing people together for in-person collaboration and learning from each other, while supporting flexibility about how to do this in a way that makes sense for each individual and team.

We don't enforce a minimum number of days for most roles, but you're expected to spend time at the office organically, and be at the office most days during your ramp-up or when required by your leader.
