About Position 

Join our Fraud Analytics team, where you’ll play a critical role in maintaining the security of our seamless checkout process. We believe in offering our customers a frictionless experience—during checkout, they only need to provide an email and phone number to instantly access a credit account and have their payments underwritten. It’s fast, efficient, and convenient, but it comes with the challenge of ensuring that fraud is detected and prevented in real time.

As a Data Scientist in this team, you will work alongside fraud risk experts to develop solutions that stay ahead of emerging fraud patterns. You’ll leverage technologies, including AWS, Glue, Spark, and EMR, to build monitoring systems and deploy alert mechanisms that respond instantly to suspicious activities. Your insights and models will directly influence our ability to protect both the business and our customers, ensuring that every transaction is secure without compromising the speed and simplicity of our checkout.
