You’ll take a hands-on role managing and monitoring retail credit risk exposures across merchant and consumer portfolios in a Type 3 / Segment S3 financial institution operating in the payments and acquiring space.

This role blends deep expertise in credit risk and regulation with a passion for data, automation, and AI — helping us build scalable, smart systems that keep our ecosystem safe while enabling innovation.
