Senior Full-Stack Developer

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.

- Burn-to-redeem mechanics for physical vault items
- Marketplace integration (OpenSea's Seaport or Reservoir Protocol)
- Basic social features (leaderboards, referrals, etc.)
