Design and ship audit-ready smart contracts and full-stack dApps for protocols securing real on-chain value.

You will own smart contract systems end to end — from threat modelling and architecture through implementation, testing, and mainnet deployment. Our contracts secure billions in on-chain value, so security and correctness are not negotiable.

What you'll do

  • Architect and implement Solidity (and occasionally Vyper) contracts for exchanges, DeFi protocols, and token systems
  • Write comprehensive test suites — unit, fuzz, and invariant testing with Foundry and Echidna
  • Lead internal security reviews and coordinate third-party audits
  • Build the full-stack dApp layer with React, wagmi, and ethers.js

Requirements & nice-to-haves

  • 5+ years of software engineering, 3+ years shipping production smart contracts
  • Deep Solidity expertise and a security-first mindset
  • Experience with Foundry, Hardhat, and EVM internals
  • Track record of contracts deployed to mainnet
  • Nice to have: formal verification, Cairo/Solana, or audit experience
