You'll also analyze complex datasets, design metrics, build dashboards, and collaborate closely with stakeholders across the business to drive decision-making and optimize outcomes.

• Partner with cross-functional teams (Business, Product, and Engineering) to translate business requirements into data-driven solutions

What you'll need
• 7+ years of experience in data science, quantitative modeling, or a data-focused role (product analytics, business analytics) with demonstrated high impact in fraud or risk contexts

• Strong hands-on experience with Python/R and SQL is essential, with Spark being a nice to have

• Expertise in BI tools such as Tableau, Sigma, or Metabase

• Proven ability to structure and analyze complex data using techniques like EDA and cohort analysis, and communicate findings effectively to both technical and non-technical audiences, including clients

• Sharp critical thinking and creative problem-solving skills with a bias toward action

• Proficiency in defining, tracking, and communicating performance metrics
