Data Scientist, Fraud

Stripe Stripe · Fintech · Canada · 7112 Data Science

Data Scientist role focused on building and improving machine learning models for fraud detection and loss management systems within Stripe's financial infrastructure. The role involves working with supervised and unsupervised ML, statistical modeling, causal inference, and experimentation, with a strong emphasis on moving models from research to production and driving measurable impact on financial integrity and user trust. Experience with fraud/risk/financial crimes and deploying models in production is required.

What you'd actually do

  1. build and improve the models that power Stripe's fraud detection and loss management systems
  2. work closely with Fraud Engineering and Risk Operations to move models from research to production
  3. use data to surface insights that shape fraud strategy across the business
  4. apply supervised and unsupervised machine learning, statistical modeling, causal inference, optimization, and experimentation to some of the most consequential risk problems in global payments
