About OnePay
OnePay is a leading consumer fintech platform that empowers millions of Americans by transforming how they manage their finances.

Additionally, we collaborate with employers, HCM providers, gig economy platforms, and others to deliver embedded financial solutions to countless employees and frontline workers.
Backed by Walmart, the world’s largest retailer, and Ribbit Capital, a prominent investor in fintech, we possess the unique capability to scale, distribute, and innovate in ways that are truly groundbreaking.
What differentiates OnePay is our pace. Our customers need swift solutions, and we share that urgency. We are seeking individuals who are:
- Proactive and eager to take initiative
- Driven by a sense of urgency
- Highly skilled yet humble
- Comfortable with a dynamic work environment
