OnePay

OnePay operates as a consumer fintech platform that integrates banking, high-yield savings, credit cards, point-of-sale lending, investing, and cryptocurrency into a single application. The company serves millions of Americans as well as employees and frontline workers through partnerships with employers, gig platforms, and HCM providers. Backed by Walmart and Ribbit Capital, the organization focuses on delivering financial services designed to help users grow their money and manage everyday banking needs.

In the domains of artificial intelligence and machine learning, OnePay applies machine learning and foundation models—including transformer-based and graph-based architectures—to customer, transaction, and merchant data. AI initiatives support core platform capabilities such as integrating agentic AI into risk decision flows, building threat detection and workflow automation systems, and driving personalization and fraud strategy efforts across products.

The open roles indicate that OnePay is building cross-functional teams spanning engineering, applied science, research, security, product strategy, and legal compliance. Open positions feature individual contributor and internship opportunities across varied seniority levels. While most technical and engineering roles are listed as remote across the United States, certain positions such as the legal and compliance internship are based out of New York City in a hybrid format.
