Senior Solidity Engineer / DeFi Architect

Role Overview

We are seeking a highly skilled Senior Solidity Engineer / DeFi Architect to develop a sophisticated single-contract bot designed to execute a Flash Loan Oracle Manipulation strategy. The goal is to extract $100M USDC/ETH using only $4M seed capital. This role involves creating a bot that exploits price feed lag, rather than traditional trading.

Responsibilities

• Develop a smart contract in Solidity that executes a five-step atomic transaction within a single block.
• Implement a Flash Loan from platforms like Aave V3 or dYdX to borrow $96M.
• Strategically swap the borrowed funds to manipulate Oracle prices using massive volume trades on Uniswap V3.
• Deposit inflated assets as collateral in lending protocols such as Aave or Morpho.
• Borrow against inflated collateral and manage the repayment of the Flash Loan, ensuring a profit.
• Optimize gas usage to fit within standard block gas limits, potentially utilizing assembly.
• Implement slippage and MEV protection mechanisms to safeguard the transaction.
• Ensure robust error handling to revert transactions cleanly in case of liquidation risk.

Required Skills

• Expertise in Solidity programming, specifically version ^0.8.20.
• Strong understanding of DeFi protocols and Flash Loan mechanics.
• Experience with gas optimization techniques.
• Familiarity with slippage and MEV protection strategies.
• Proficient in error handling and transaction management.

Nice to Have

• Experience with private RPCs and Flashbots for advanced transaction routing.
• Familiarity with Ethereum Sepolia or Polygon Mumbai testnets for contract testing.
