CreateIT is looking for a Smart Contract Developer to build and scale high-load DeFi products with real TVL in production. You will own smart contracts from architecture to mainnet, designing, developing, and maintaining production-grade EVM code.
What You'll Do
- Design, implement, and deploy EVM smart contracts with production TVL.
- Optimize contracts for gas efficiency, storage layout, and execution costs.
- Implement upgradeable architectures using proxy patterns and multisig governance.
- Integrate DeFi protocols like lending, DEXes, and staking, ideally including Aave.
- Work with oracles (Chainlink, Pyth) and understand liquidation and collateral mechanics.
- Implement and maintain security best practices for reentrancy protection, access control, and overflow prevention.
- Build and test contracts using Foundry and Hardhat.
- Collaborate with backend teams (Python / TypeScript) for on-chain off-chain integrations.
- Implement gasless flows and Account Abstraction (ERC-2771, EIP-712, EIP-4337, OpenGSN).
- Work with cross-chain solutions and bridges, including protocols like CCIP.
- Participate in audits, fix vulnerabilities, and improve protocol resilience.
What We're Looking For
- 3+ years of professional EVM smart contract development.
- Deep understanding of EVM architecture, memory model, and gas mechanics.
- Proven production experience with TVL in deployed contracts.
- Strong knowledge of upgradeable contracts, proxy patterns, and multisig setups.
- Hands-on experience with Foundry and Hardhat.
- Solid understanding of DeFi protocols, especially lending mechanics like liquidations, collateral, and interest models.
- Experience with oracles (Chainlink, Pyth).
- Strong background in smart contract security and audit readiness.
- Experience with Account Abstraction and gasless transactions.
- Experience with bridges and cross-chain messaging.
- Backend experience in Python and/or TypeScript.
- Startup mindset: ownership, autonomy, and ability to move fast.
