Full-Stack Developer (AI-Assisted Development)

About Us
Clean Nutra is one of the fastest-growing health and wellness brands in the world, powering over 12,000+ daily Amazon orders, 200+ product SKUs, and a rapidly expanding DTC and TikTok presence. Behind the scenes, we're building an internal platform, an AI-powered operating system designed to run our entire company from end to end: marketing, payments, inventory, purchasing, forecasting, and more.
Our mission is to create the most advanced eCommerce operating platform in the industry, automating 90% of business operations across logistics, finance, and marketing.
We're looking for a Full-Stack Developer who leverages AI coding tools like Claude Code and Cursor to ship production-ready features at 3–5x the speed of traditional development workflows.
Role Overview
This isn't a traditional developer role. We're looking for someone who has fully embraced AI-assisted development and uses tools like Claude Code, Cursor, and similar AI coding assistants as core parts of their daily workflow, not as novelties.
You'll work across our entire stack, rapidly building and iterating on features for our internal platform system, Shopify integrations, internal dashboards, payment infrastructure, and AI automation tools. Speed and output matter here. We want someone who can turn a Loom video or Slack message into a deployed feature within hours, not weeks.
Core Responsibilities
Rapid Feature Development

Build and ship full-stack features across our internal platform using AI-assisted workflows
Use Claude Code, Cursor, and similar tools to accelerate coding, debugging, new feature implementation, and documentation
Turn product requirements into working code quickly we measure in days, not sprints
Write clean, maintainable code even at high velocity
Payment Processing & Checkout Systems

Build and maintain PCI-compliant checkout pages and payment flows
Develop post-purchase upsell funnels with one-click functionality
Implement credit card vaulting systems for secure storage and subscription billing
Integrate with payment gateways (Stripe, NMI, Checkout Champ, or similar processors)
Build subscription management infrastructure - billing cycles, failed payment recovery, card updates, and cancellation flows
Ensure all payment systems meet PCI-DSS compliance requirements
Develop fraud prevention measures and chargeback management tools
ERP & Backend Systems

Develop and extend backend modules for inventory, purchasing, payments, and forecasting
Build and maintain API integrations with Amazon SP-API, Shopify, TikTok Shop, 3PLs, and payment gateways

Frontend & Web Development

Build React-based interfaces for internal tools and dashboards
Develop Checkout Champ and Shopify landing pages, funnels, and custom app integrations
Create high-converting checkout experiences optimized for mobile and desktop
Ensure seamless UX across all internal and customer-facing systems
AI Tool Integration

Help integrate AI-generated video, image, and automation tools into our internal software ecosystem
Build internal tools that leverage LLMs and other AI software APIs for marketing automation, listing optimization, and reporting
Stay current on emerging AI dev tools and bring new capabilities to the team
Collaboration & Communication

Work directly with the executive team
Translate business requirements into technical solutions rapidly
Document your work clearly so AI tools and teammates can build on it
Participate in weekly syncs with milestones, blockers, and deliverables
Qualifications

5+ years of full-stack development experience (Node.js, Python, React, or similar)
Demonstrated proficiency with AI coding tools - Claude Code, Cursor, GitHub Copilot, or equivalent. We want to see that you've shipped real projects using these tools.
Experience building PCI-compliant payment systems - checkout flows, tokenization, and secure card handling
Familiarity with subscription billing infrastructure - credit card vaulting, recurring payments, dunning management, and self-service portals
Experience with payment processors such as Stripe, NMI, Adyen, Braintree, Checkout.com
Experience with CRMs such as Checkout Champ, sticky.io, or other similar e-commerce focused CRM
Strong understanding of API integrations, databases, and cloud infrastructure
Experience with eCommerce platforms (Shopify, Amazon) preferred
Ability to work independently and move fast without constant oversight
Excellent written communication - you'll be prompting AI tools as much as writing code
Comfort with ambiguity; able to take a rough idea and figure out the best implementation
