Remote Next.js Developer – Fintech (Full-Stack) - Remote

About the Role We’re a fintech company building financial infrastructure that touches real money, real accounts, and real users across multiple markets. Our product surface includes banking integrations, payment flows, and data-intensive dashboards — the kind of work where bugs have consequences and architecture decisions compound over time. We’re looking for a senior full-stack developer who can own features end-to-end, make sound technical decisions independently, and deliver production-ready code — without needing hand-holding or weekly check-ins to stay on track. This is a long-term remote engagement (6+ months). If you’re looking for a short sprint or a quick gig, this isn’t the right fit. What You’ll Work On • Building and maintaining full-stack features in Next.js (App Router) and TypeScript • Designing and consuming RESTful APIs for financial data — rates, transactions, balances, account flows • Implementing secure, performant UI components and data-fetching layers • Collaborating async-first with a lean team on a product that needs to scale reliably • Participating in architecture and code review with a high bar for clarity and maintainability
