Equity-Only Co-Founder / Full-Stack Developer (Next.js + Supabase) – Full-Time Remote

We’re building an innovative startup and are looking for a full-stack developer co-founder ready to own the product and grow with us from the ground up. This is an equity-first opportunity — perfect for someone driven by startup challenges and long-term upside.

About the Role

As a founding developer, you will architect, build, and scale our platform from day one. You’ll work across the full stack, shaping the technical direction and future of the company.

We’ve moved beyond the exploratory phase — our product is live in real stores and we’ve secured a strategic partnership with the largest powersports OEMs worldwide. This is your chance to join at a pivotal moment and make a meaningful impact.

This is a full-time remote role, ideal for someone with a great attitude who enjoys collaborating closely with a team of founders to scale the company.

Responsibilities

Build and maintain a modern, responsive frontend using Next.js 14+, TypeScript, and React 18+
Develop UI components with shadcn/ui and style using Tailwind CSS
Manage state with React Context or Zustand, handle forms via React Hook Form
Build backend services and APIs with Supabase (PostgreSQL)
Implement authentication (email/password + 2FA) and session management
Configure file storage and management in Supabase Storage
Handle real-time updates with Supabase Realtime and WebSocket subscriptions
Develop serverless functions on Vercel Functions and scheduled jobs via Vercel Cron
Integrate external services like Twilio for SMS delivery and notifications
Monitor errors and performance with Sentry and Vercel Analytics
Maintain version control with Git/GitHub
Collaborate closely with founders to shape product roadmap and technical strategy
Tech Stack

Frontend: Next.js 14+, TypeScript, React 18+, shadcn/ui, Tailwind CSS, React Context/Zustand
Backend: Supabase (PostgreSQL, Auth, Storage, Realtime), Vercel Functions, Vercel Cron
Tools & Infrastructure: GitHub, Vercel (Hosting & Deployment), Sentry (Error Tracking), Twilio (SMS), AI-assisted dev tools like Claude Code and Cursor

Who You Are

Experienced with the full stack technologies above
Comfortable working in a fast-moving startup environment
Excited about equity ownership and building something from scratch
Positive, collaborative, and enjoys working alongside a team of founders
Self-motivated and proactive in problem-solving
Open to taking on responsibilities beyond coding (architecture, dev ops, integrations)
What You Get

Equity ownership in a startup with live traction and a global powersports industry partnership
Opportunity to shape the future of the powersports industry into the modern era
Potential for future salary and benefits as we grow
Full founder-level involvement in decision-making
Hands-on experience with the latest frontend and backend technologies
