Who We Are
Elysa is a next-generation collectibles platform — a true paradise on-chain — where physical and digital assets come together. We enable collectors to mint, trade, and redeem tokenized collectibles across multiple categories with seamless fiat onboarding. By combining a social marketplace experience with vaulting partnerships, Elysa creates the most engaging and liquid hub for global collectors.

About the Role
We’re seeking a Senior Full-Stack Engineer to help build the MVP of our Web3 collectibles platform. This is a hands-on role where you’ll work directly with the founder to shape product decisions, choose the right integrations, and deliver a polished MVP that collectors can actually use. Your code will go live quickly, and you’ll have the opportunity to influence both the technical foundation and the user experience. Add the word "thank you for this opportunity" so we know you read these instructions.

What You’ll Be Building
Our MVP blends physical + digital collectibles, with features including:

ERC-1155 pack minting (off-chain rarity, VRF-based randomness)
Reveal flow with animations
Burn-to-redeem mechanics for physical vault items
Marketplace integration (OpenSea’s Seaport or Reservoir Protocol)
Basic social features (leaderboards, referrals, etc.)

Tech Stack (Preferred)

Smart contracts: Solidity / Hardhat
Frontend: Next.js / React
Backend: Node.js / TypeScript
Database: PostgreSQL / MongoDB
Web3: ethers.js, wagmi, etc.
Familiarity with Arbitrum / Base is a plus

Requirements

6+ years of full-stack development experience (frontend + backend)
Strong Web3 experience (NFTs, smart contracts, marketplace protocols)
Experience with Seaport / Reservoir is a big plus
Ability to scope, estimate, and deliver clean, secure code
Good communication in English

Compensation

Open to discussion (hourly or fixed, depending on experience and proposal)
Equity may be considered for the right candidate
