## Description

Senior Developer (TypeScript + Node.js) - Fintech - 100% Remote At this company, everyone in tech carries the "Tech Generalist" title on purpose: no one is only frontend, only backend, or only data. Every engineer has a specialization but works across the stack. Engineers pick up projects end-to-end and rotate between initiatives rather than staying in silos. We are actively looking for this hire to be an AI Builder - someone who has genuinely adopted AI in their daily engineering workflow and can become an internal reference across the team. What you'll do - Design, develop, and maintain end-to-end systems (frontend and backend) - supporting customer-facing workflows and internal backoffice operations. - Evolve the architecture for scalability, reliability, and security, making pragmatic tradeoffs between speed and long-term maintainability. - Design and maintain the platform's core financial systems: payment orchestration, ledger infrastructure, underwriting engines
