As a Staff Engineer at OnePay, you’ll serve as a highly versatile technical leader and contributor, tackling complex engineering challenges across multiple domains. Rather than being tied to a single product or team, you’ll be deployed as a utility player where the business needs you most—whether that’s scaling systems, guiding architectural decisions, or accelerating delivery of user-facing features. You’ll collaborate broadly with engineering, product, and design, and play a pivotal role in shaping OnePay’s technical foundation and customer experience.
