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. Engineers pick up projects end-to-end and rotate between initiatives rather than staying in silos.
Design, develop, and maintain end-to-end systems (frontend and backend) — supporting customer-facing workflows and internal backoffice operations.
Design and maintain the platform's core financial systems: payment orchestration, ledger infrastructure, underwriting engines, reconciliation pipelines, and real-time deal tracking. Integrate third-party financial APIs (Taktile, Modern Treasury, Kantox) to automate data ingestion, risk evaluation, and cash movement workflows.
Raise the team's bar through thoughtful system design, high-quality code reviews,



and mentorship — including acting as an internal reference on AI-assisted engineering.
