Senior Frontend Engineer

Summary

Build the Web2 frontend from scratch using React/Next.js and TypeScript, then integrate Web3 features for Pet360’s blockchain-based pet ecosystem in Brazil.

About Pet360
Pet360 is the first blockchain-based pet ecosystem in Brazil. With 160 million pets and zero blockchain infrastructure today, we're building a complete Web3 layer to transform pet care - from NFT passports and vaccine certificates to smart contract adoptions and on-chain pet insurance.
Our Web2 platform is 80% complete. We're now building the Web3 layer from scratch. This is a greenfield opportunity - you'll shape the frontend architecture and build it from the ground up.

The Role
We're looking for a Frontend Engineer to join our founding team and own the frontend experience. For now, we're focusing on completing the Web2 layer, with Web3 frontend integration coming later.

Complete frontend from scratch using React/Next.js and TypeScript
All Web2 features (OTP endpoints, appointment status, forms, pages)
Project structure and architecture setup
Responsive, intuitive interfaces for users in Brazil
Work alongside backend developers

Requirements
3+ years of frontend development experience
Strong proficiency in React/Next.js and TypeScript
Experience with state management (Redux, Zustand, or Context API)
Understanding of responsive design and Tailwind CSS
Experience with Web3/wallet libraries (Wagmi, RainbowKit, Ethers.js) is a plus
Professional English proficiency

What We Offer
Fully remote
$70–$100 per hour (negotiable)
Payment: Crypto (USDC/USDT) or fiat - your preference
30+ hours per week
Greenfield project - build from scratch
