About The Position

Nymbus is seeking an AI Product Builder to join their innovative team. This role is central to the company's AI-first methodology, responsible for transforming product vision into working software. The AI Product Builder will design, specify, and build products using AI-assisted workflows, collaborating closely with an Architect and a Shipper within a dedicated squad. This is a full-stack role that involves authoring specifications, writing code, designing interactions, and rapidly iterating to deliver outcomes end-to-end, from problem definition through production operation. The ideal candidate will have a strong background in fintech, a technical fluency across the stack, and a proactive, experimental mindset.

The AI Product Builder operates as the primary maker within the "squad triad model," which also includes an Architect (responsible for system design and technical integrity) and a Shipper (responsible for delivery, quality, and release). Together, this triad owns the entire product lifecycle. The AI Product Builder leverages tools like Kiro and Claude to accelerate product creation, defining APIs, data models, and interaction patterns in partnership with the Architect, and collaborating with the Shipper on acceptance criteria and release readiness. Domain expertise in areas such as core banking, digital banking, lending, or payments and cards is highly valued.

Requirements

• 5 plus years in product and/or engineering roles within fintech, banking, or financial services.
• Experience working with core banking or digital banking platforms.
• Strong understanding of complex, regulated environments and financial workflows.
• Proven ability to design and build systems and workflows, not just define requirements.
• Track record of shipping working software, not just producing documentation.
• Strong hands-on development capability across front-end and/or back-end technologies.
• Ability to own implementation end-to-end within a product domain.
• Comfort working across the stack as needed to deliver complete features.
• Active, hands-on experience with AI-assisted development workflows.
• Demonstrated use of AI tools for specification, code generation, and iteration.
• Willingness to experiment with tools and continuously improve AI-augmented building practices.
• Comfort operating in a spec-first, AI-first development methodology.
• High Agency: Takes ownership of outcomes and drives work forward without waiting for permission or heavy process. Identifies what should be built and builds it.
• Problem Solver: Thrives in ambiguity. Frames problems clearly, explores solution spaces, and converges on practical approaches quickly.
• Builder Mindset: Measures success by what ships. Prefers building and iterating over planning and discussing. Gets energy from creating working software.
• Experimenter: Tests ideas quickly using AI tools and iterates based on results. Explores multiple approaches before committing.
• Quality Driven: Focuses on correctness, clarity, and long-term maintainability. Treats specifications and code as durable assets.
• Scale Oriented: Designs with performance, extensibility, and operational realities in mind from the start.
• Ownership: Takes pride in end-to-end delivery. Does not hand off and walk away — stays accountable through production.

Nice To Haves

• Understanding of REST APIs, data modeling, and system interactions.

Responsibilities

• Own end-to-end product design from problem definition through system behavior and user experience.
• Author clear, testable, implementation-ready specifications using AI-assisted workflows.
• Define APIs, data models, and interaction patterns in partnership with the squad Architect.
• Translate business requirements and domain knowledge into buildable system specifications.
• Build working software using AI-assisted development workflows as the primary creation method.
• Generate, refine, and implement product and technical specifications using spec-driven development.
• Prototype and validate solutions rapidly before committing to full implementation.
• Push through ambiguity — when requirements are unclear, explore, propose, and build to learn.
• Leverage AI tools as co-developers, not just assistants, to multiply output and quality.
• Partner daily with the Architect on API design, data modeling, and system architecture decisions.
• Coordinate with the Shipper on acceptance criteria, testability, and release readiness.
• Participate directly in technical design discussions and tradeoff decisions with the full triad.
• Surface blockers, risks, and dependencies to the squad early and proactively.
• Maintain shared context with squad partners through specifications, documentation, and working demos.
• Apply expertise in one or more domains such as: Core Banking, Digital Banking, Lending, or Payments and Cards.
