Job Title: Blockchain Security Developer (ERC20 / TRC20 Testing Environment) Location: Remote Employment Type: Contract / Full-Time Sector: Cybersecurity / Blockchain Auditing About the Role We are looking for a skilled Blockchain Developer to join our security testing division. In this role, you will be responsible for simulating advanced threat scenarios to help us fortify our infrastructure. Your primary focus will be to create test-specific USDT flash wallets and simulate the transfer of assets to ERC20 and TRC20 contract addresses. This is strictly a defensive security role. You will be building controlled environments to test our monitoring systems, smart contract vulnerabilities, and exchange protocols against potential cyber attacks. Key Responsibilities • Develop and deploy temporary USDT flash wallets on testnet (and controlled mainnet environments) for stress-testing purposes. • Engineer scripts to simulate the transfer of test assets from flash wallets to specific ERC20 (Ethereum) and TRC20 (Tron) contract addresses. • Work closely with the red team to simulate "dusting" attacks, fake deposit scenarios, and network congestion tests. • Document the behavior of assets during transfer to identify potential security loopholes. • Stay updated on the latest flash loan attack vectors and malicious wallet creation techniques to ensure our testing remains relevant. Required Skills & Experience • Strong proficiency in Solidity (ERC20) and/or Tron Smart Contracts (TRC20). • Experience with Web3.js, Ethers.js, or TronWeb. • Deep understanding of the USDT token standard on both Ethereum and Tron networks. • Familiarity with blockchain explorers and debugging transactions. • Security-first mindset: You understand how malicious actors operate and can replicate those methods in a safe, sandboxed environment. • Experience with Hardhat, Truffle, or Foundry for testing. Nice to Have • Previous experience in blockchain security auditing or penetration testing. • Knowledge of Node.js or Python for automation scripts.
