AI Product Builder
ABOUT NYMBUS
Nymbus (https://nymbus.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 product builder. This role is the engine of the squad — the person who takes product intent and turns it into working software. You will design, specify, and build products using AI-first methodology, working hand-in-hand with your Architect and Shipper to deliver outcomes end-to-end.
WORK ENVIRONMENT:
We are a remote first company, with occasional travel required for team collaboration or client engagement.
POSITION SUMMARY:
At Nymbus, the AI Product Builder is the primary maker in our squad triad model.
You are responsible for transforming product vision into reality. Working within a dedicated squad alongside an Architect (who owns system design and technical integrity) and a Shipper (who owns delivery, quality, and release), you own the build — from specification through implementation. You operate with an AI-first, spec-first mindset, leveraging tools like Kiro and Claude to accelerate every phase of product creation.
This is not a traditional developer or product owner role. You are a full-stack product builder who authors specifications, writes code, designs interactions, and iterates rapidly using AI-assisted workflows. You own the "what" and the "how" — translating domain problems into working, shippable software.
THE SQUAD TRIAD MODEL
You operate as one-third of a high-autonomy squad:
Builder (This Role): Owns product intent, specification, and implementation. You are the primary creator — designing system behavior, authoring specs, and iterating with AI tools to produce working software.
Architect (Your Partner): Owns system design, technical integrity, and cross-squad consistency. The Architect ensures your solutions are scalable, maintainable, and aligned with platform architecture. You collaborate daily on data models, API contracts, and integration patterns.
Shipper (Your Partner): Owns delivery, quality assurance, release management, and operational readiness. The Shipper ensures what you build meets quality standards, passes validation, and reaches production reliably. You collaborate on acceptance criteria, test coverage, and deployment strategy.
Together, the triad owns outcomes end-to-end — from problem definition through production operation.
ESSENTIAL JOB FUNCTIONS / RESPONSIBILITIES
Product Design and Specification
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 including account structures, posting models, settlement processes, and data integrity
Digital Banking including account opening, onboarding workflows, KYC and CIP, and user experience design
Lending including loan lifecycles, servicing logic, payments, and exception handling
Payments and Cards including transaction flows, authorization and settlement, and integration patterns
QUALIFICATIONS:
Product & Fintech
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
Technical Fluency
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
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.
WHAT WE ARE EXPLICITLY NOT LOOKING FOR
Backlog administrators who manage tickets but do not build
Requirement translators removed from implementation
Developers who wait for fully specified work before starting
People uncomfortable with ambiguity or cross-functional ownership
Those unwilling to adopt AI-first development practices
Individuals who view their role as narrowly scoped to a single function
