Who We Are:

Elysa is a next-generation collectibles platform — a true paradise on-chain — where physical and digital assets come together.

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.

  • 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:
