  • Manage wallet connections (MetaMask, WalletConnect, Coinbase Wallet) and transaction flows.
  • Work with design and marketing teams to deliver seamless UX/UI for on-chain operations.

3. Infrastructure & Interoperability

  • Connect DApp components with backend services (Node.js, Express, GraphQL, Firebase, etc.).
  • Integrate oracles, indexing solutions (The Graph), and third-party APIs.
  • Optimize dApp performance across multiple networks and ensure cross-chain compatibility (Layer2, bridges).

  • Strong problem-solving and documentation skills; able to work in fast-moving Web3 teams.

Preferred Experience

  • Built or contributed to public blockchain projects (GitHub or portfolio links welcome).
  • Experience with cross-chain bridges, zk-proofs, or L2 rollups.
  • Knowledge of backend indexing (Subgraph / Dune / SQL) and smart contract audits.
  • Understanding of token issuance & DAO governance frameworks (Gnosis Safe, Snapshot, Tally).

Compensation & Benefits

  • Competitive salary + performance bonus + token/equity incentives.
  • Flexible remote work policy; global team collaboration.
