Job Description
We are building a decentralized cryptocurrency trading platform that allows users to trade digital assets in an automated and trustless manner—without relying on a centralized exchange. Our platform will leverage the Polygon blockchain for fast and cost-effective transactions.
Key features of the platform:
1. Staking & Farming – Users can lock up tokens to earn rewards.
2. Lottery System – A randomized token reward system.
3. NFTs & NFT Marketplace – Buy, sell, and trade unique digital assets.
Requirements:
We are looking for an experienced blockchain developer with expertise in smart contract development, DeFi protocols, and backend integration. The ideal candidate should have:
1. Strong experience in Ethereum and Polygon-based smart contract development (Solidity).
2. Expertise in DeFi mechanisms, staking, yield farming, and liquidity pools.
3. Ability to optimize gas fees and improve transaction efficiency.
4. Hands-on experience with backend development (Node.js, MongoDB) and blockchain integration.
5. A solid understanding of security best practices to mitigate potential vulnerabilities and hacks.
6. The ability to work independently in a fast-paced startup environment with minimal supervision.
Responsibilities:
1. Develop and deploy smart contracts for the LMNG token, staking, farming, lottery, and NFTs.
2. Optimize transactions to reduce gas fees and enhance platform efficiency.
3. Integrate the backend (Node.js, MongoDB) with blockchain smart contracts.
4. Implement robust security measures to safeguard user assets.
5. Collaborate with our team to bring the platform to market.
