Solidity Smart Contract Developer

As a Solidity Smart Contract Developer, you will be working on three interconnected products: Mining Staking Ecosystem, NFT Marketplace, and SmartCommerce. You will design and implement smart contracts from scratch, optimize gas efficiency, and prepare for the next phase of staking features. You will also work on building on-chain payment acceptance and validation logic, handling edge cases, and creating settlement logic that bridges on-chain payments to off-chain fulfillment.

What You Will Do

Your day-to-day work will involve designing and implementing NFT minting contracts, building trading logic, implementing the staking engine, and creating settlement logic. You will also write comprehensive test suites for every contract, optimize gas usage, and prepare contracts for third-party security audit.

Why It Might Be a Fit

We are looking for a developer with 2+ years of experience writing production Solidity with deployed, verified contracts. You should have a strong understanding of smart contract vulnerabilities and hands-on experience with Hardhat or Foundry. You should also be familiar with OpenZeppelin contracts and EVM token standards.

Requirements

• 2+ years writing production Solidity with deployed, verified contracts
• Strong understanding of smart contract vulnerabilities
• Hands-on experience with Hardhat or Foundry
• Familiarity with OpenZeppelin contracts and EVM token standards

• Clear written communication in English for async collaboration

Benefits

• $138,000 – $181,700 USD/year— competitive and negotiable based on experience

• Ground-floor timing — proven foundation (live staking) + greenfield products (marketplace, SmartCommerce)
• Security-first culture — we budget for audits and take them seriously
• Small, focused team — your voice matters in every architectural decision
