We’re building the first group payment platform that integrates directly into merchant checkouts. Backed by real user demand and selected by Lanzadera (Spain’s top startup accelerator), OnePool is looking for a technical cofounder to lead the development of our MVP and shape the future of collaborative payments. What you’ll do: - Lead the architecture and development of our first product - Work closely with PSPs integrations - Build and maintain APIs, webhook logic, and payment flow orchestration - Own technical decisions from infrastructure to deployment - Define our engineering culture and roadmap as a core founding member. Nice-to-haves (not all required): Next.js, Go/Python/Node, typescript, payment integrations, full-stack dev, early-stage products, fintech or checkout UX. About us: We’re a small team with backgrounds in product, growth, and early-stage startups. OnePool simplifies one of the most frustrating payment flows for users and businesses alike — and we’re ready to build fast with the right tech partner on board.
