Full Stack Developer

Full Stack Developer Company: Lansdowne Payments (lansdownepayments.com) Location: Remote / Hybrid - Europe, Latvia (CET +/- 3 hours) Type: Full-time Sector: Fintech - Payments, FX & Digital Assets About Us Lansdowne Payments is a FINTRAC-regulated Money Services Business operating across payments, FX, and virtual currency / stablecoin services. We serve businesses across the payments ecosystem — including clients underserved by traditional banks — and we're building out the core technology that powers everything we do. We work in a lean, fast-moving environment. AI-assisted development is a core part of how we ship — not an experiment, but a baseline expectation. The Role We're looking for a Full Stack Developer to own and evolve our internal operations platform and client-facing portal. You'll work across the full stack: Next.js App Router, TypeScript, PostgreSQL with Prisma ORM, and a rich MUI-based UI — all deployed on Azure. The codebase follows strict security, audit, and compliance patterns appropriate to a regulated financial services business. You'll work directly with the founding team, shipping features end-to-end: API routes, CQRS command handlers, repositories, data grids, upload forms, and everything in between.
