The AI Product Builder — Payments will help define and build the next generation of payment capabilities at Nymbus, including support for multiple payment rails, networks, message standards, settlement models, and integration patterns.
You will own the transformation of complex payment-domain problems into working, production-ready software.
You will design system behavior, author implementation-ready specifications, shape APIs and data models, prototype solutions, and participate directly in implementation using AI-assisted development workflows.
You must understand how money moves—not only at the feature or requirements level, but at the system, message, transaction, settlement, and operational levels.
You understand that the difficult parts of payments live in timeouts, duplicate messages, reversals, returns, cutoffs, partial failures, unavailable endpoints, liquidity constraints, and ambiguous transaction states.
You will not simply maintain a backlog and hand requirements to an engineering team. You are the primary product maker and payments-domain builder within the squad.
