AI Product Shipper - Payments

com/) is not just a leader in fintech; we are a community of innovators passionate about reimagining banking. Our modern core platform and cloud based technology serve as the backbone for financial institutions eager to modernize and excel. Nymbus is building the next generation of fintech platforms and that requires a new kind of delivery leader.

This role is the quality and release backbone of the squad — the person who ensures what gets built actually reaches production reliably, correctly, and on cadence. You will own delivery, validation, and operational readiness using AI-first methodology, working hand-in-hand with your Builder and Architect to ship outcomes end-to-end. WORK ENVIRONMENT: We are a remote first company, with occasional travel required for team collaboration or client engagement.

POSITION SUMMARY: 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. At the heart of this role is a straightforward but demanding mandate: help us build sophisticated, extensible payment capabilities that financial institutions can depend on. 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.

Requirements

level, but at the system, message, transaction, settlement, and operational levels. You should be able to trace a payment from initiation through validation, routing, clearing, settlement, posting, reconciliation, and exception handling. 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.

-writer role.

to an engineering team. You are the primary product maker and payments-domain builder within the squad. Hands-on software development experience is strongly preferred.

We will also consider an exceptionally technical payments expert who has demonstrated the ability to design buildable software systems, reason at the code and data-model level, and work directly with engineers through implementation. The ideal candidate may have previously operated as a principal engineer, payments architect, payment-platform builder, technical product leader, or deeply technical payments operator. Regardless of title, you have personally helped build or substantially shape sophisticated payment infrastructure.

THE SQUAD TRIAD MODEL You will operate as one-third of a high-autonomy squad: Builder — This Role: Owns payment-product intent, detailed system behavior, specification, and implementation. You are the primary creator, translating payment-domain problems into working software and using AI tools to accelerate design, development, and iteration. Architect — Your Partner: Owns system architecture, technical integrity, and cross-squad consistency.

You will collaborate daily on service boundaries, payment state models, API contracts, data architecture, integration patterns, security, scalability, and resilience. Shipper — Your Partner: Owns delivery discipline, quality assurance, release management, and operational readiness. You will collaborate on acceptance criteria, automated testing, rail certification, observability, deployment, production validation, and incident readiness.

Together, the triad owns the complete outcome—from problem definition through production operation.
