The Role

Were looking for a Fullstack Engineer to build the systems and interfaces that power global transactions for thousands of merchants.

What Youll Do

- Build the core services and interfaces that drive high-scale, global payment flows - owning features end-to-end from API to UI

- Work directly with product and design to ship features rapidly from idea to production, and contribute to refining our design system for visual consistency

- Design and ship frontend in React, TypeScript, Tailwind, and TanStack/React Query

- Strong working knowledge of React, TypeScript, Tailwind, and TanStack/React Query we are not adaptable on the frontend stack

- Solid backend fundamentals we use Java, Spring Boot, and MongoDB, but were adaptable here. If youre solid in another stack (Node.js, Go, Python, Kotlin, etc.) and willing to ramp up on ours, wed love to talk

- Comfort moving fluidly between backend and frontend within the same feature solid instincts for API design, data modeling, and system tradeoffs

- Strong sense of UX and visual design, and an eye for polished interfaces

- Strong communication skills, curiosity, speed, and willingness to learn in a high-growth environment
