AI Product Builder

About the role

Nymbus (https://nymbus.com/) is a fintech leader committed to reimagining banking through innovation. As an AI Product Builder, you'll transform product visions into reality, collaborating closely with an Architect and Shipper to deliver end-to-end outcomes.

Work environment

We are a remote-first company with occasional travel for team collaboration or client engagement.

Position summary

The AI Product Builder operates as one-third of a high-autonomy squad: the primary creator, the system designer, and the delivery manager. You're responsible for product design, specification, and implementation, while partnering with the Architect and Shipper to ensure system integrity and quality.

Squad triad model

• Builder (This Role): Owns product intent, specification, and implementation. Designs system behavior, authoring specs, and iterating with AI tools to produce working software.
• Architect: Owns system design, technical integrity, and cross-squad consistency. Ensures solutions are scalable, maintainable, and aligned with platform architecture.
• Shipper: Owns delivery, quality assurance, release management, and operational readiness. Ensures what you build meets quality standards, passes validation, and reaches production reliably.

Essential job functions / responsibilities

• Use AI tools (Kiro, Claude) to rapidly iterate on designs, edge cases, and alternative approaches.
• 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.
• AI-First Building and Implementation:
• 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.
• Squad Collaboration:
• 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.
• Domain Ownership (Fintech Systems)
• Apply expertise in one or more domains such as: Core Banking, Digital Banking, Lending, Payments and Cards.

Qualifications

• Product & Fintech: 5+ 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.
• Technical Fluency: Strong hands-on development capability across front-end and/or back-end technologies.
• Comfort working across the stack as needed to deliver complete features.
• Bonus - Understanding of REST APIs, data modeling, and system interactions.
• AI-First Mindset: 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.

CORE TRAITS

• 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.
