I’m looking for a senior-level smart contract engineer to take the lead on the core contracts of our new Vault. The contracts will live on Ethereum and must automate a full financial workflow:

• Interest calculations
• Recurring payments
• Asset transfer management

Your mandate is to design, code, test, and document everything required for these automated financial processes while keeping gas usage practical and the codebase audit-ready. Solidity 0.8.x, Hardhat (or Foundry), and thorough unit + integration testing are expected as part of the delivery.

Clean, upgrade-friendly architecture, detailed NatSpec docs, and an internal walkthrough of the deployed contracts will serve as the acceptance criteria. If you have a track record of shipping production-grade DeFi vaults or similar protocols, let’s talk.

Compensation: $75–$100 per hour.
