Smart Contract Developer – DeFi / Token Infrastructure

An early-stage, well-funded cryptocurrency startup (name under wraps) is preparing for public launch. We are building a lean engineering team from the ground up.

We seek a Smart Contract Developer who can independently design, implement, and deploy secure blockchain protocols – bridging product requirements with on-chain reality.

Key Responsibilities: Smart Contract Development: Design, write, test, and deploy Ethereum-compatible smart contracts (Solidity) or Solana programs (Rust). Implement token standards (ERC-20, ERC-721, ERC-1155) and custom logic as required.

Security & Best Practices: Write comprehensive unit and integration tests using Foundry/Hardhat. Implement re-entrancy guards, access controls, and emergency pause mechanisms. Prepare code for external auditing. Deployment & Verification: Deploy contracts to testnet and mainnet.

Verify source code on Etherscan or similar. Manage upgradeable proxies (UUPS/Transparent) where applicable. Cross-Team Collaboration: Work directly with the founder and marketing lead to translate product requirements into gas-efficient, secure contract logic.

Team Building: As an early engineering hire, help define coding standards, review external contributions, and participate in interviewing future developers.

Required Qualifications: 1+ years of hands-on smart contract development with deployed code on Ethereum mainnet or equivalent L2 (Arbitrum, Optimism, Base, etc.). Provide contract addresses.

Deep understanding of EVM fundamentals (gas, storage, calldata, re-entrancy, front-running). Proficiency with Solidity and at least one framework (Foundry, Hardhat, or Truffle). Experience with OpenZeppelin libraries and contract upgrade patterns.

Ability to read and debug using block explorers and tracing tools. Strong version control practices (Git). Preferred (Not Required): Rust experience for Solana or SVM chains. Knowledge of DeFi protocols (Uniswap V2/V3, Aave, Compound forks).

Basic TypeScript/JavaScript for integration testing. Previously participated in a formal smart contract audit. Compensation & Benefits: Competitive salary (USDC/USDT or bank transfer) + significant token allocation. Fully remote, flexible hours with key team syncs.

Real ownership – architect the protocol from day one. Budget for audit tooling and gas costs. Pay: $98,670.69 - $130,872.23 per year Work Location: Remote
