Commitment: Part-Time (15–20 hrs/week)

Compensation:No Salary - Equity Only (salary follows funding)

About Us

Suportr League is building a new category at the intersection of sports fandom, loyalty, and gamification.

We have traction, a working MVP, and are moving toward our pre-seed raise. We are seeking a React Native Developer cofounder to take our mobile experience from prototype to platform.

The Opportunity

You won’t be a cog in a team, you’ll be the architect of our iOS/Android front end. If you can turn complex application flows, real-time interactions, and backend services into a polished React Native experience, this role puts you in the driving seat.

This isn’t a “dev-for-hire” job. It’s a founding seat with influence over architecture decisions, product direction, and future team hires.

What You’ll BuildYou will take ownership and lead mobile development across:

- React Native iOS + Android App—core and engagement interface

- Real-time fan interactions—WebSocket-driven loyalty features and live events

- Native integrations of RESTful API

- Authentication & wallet flows with encrypted payload handling

- Mobile dashboards and UI systems for fan performance, rewards, and inventory

- Messaging & notifications pipelines powered by WebSockets

- You’ll take our existing web-based MVP and evolve it into a native, scalable mobile product.

You MUST have the following skillsets:

- React Native (expert level, iOS/Android delivery experience)

- JavaScript / TypeScript

- State management mastery (Redux, Zustand, React Query, or similar)

- Experience consuming REST APIs & WebSockets

- Strong grasp of authentication flows (JWT)

- Ability to interpret architecture diagrams and system flows

- Expo, Vite, Tailwind, or RN styling frameworks

- Familiarity with gRPC (you won't build it, just understand the exposure layer)

- Experience integrating RESTful APIs

• - Comfort working alongside blockchain or wallet-style data flows

We value execution over buzzwords. If you know how to turn backend complexity into an elegant native app, you’re our person.

What You Get

• Founding equity—not a cosmetic title, real ownership
• A product worth shipping, not a pitch deck looking for a coder
• Influence over the technical roadmap and early hires
• Future salary post-raise
• A category-defining problem that sits at the heart of fandom, loyalty, and mobile rewards

Who This Isn’t For

• Delusional Dev’s waiting for someone to tell them what to build
• Portfolio tourists who get bored before delivery
• Devs who only want web; this is a mobile-first mandate
