Solidity / Smart Contracts Developer — BNB Smart Chain (Remote)

Job Description

About the project

NodeMeta is a Web3 project on the BNB Smart Chain. We are building two products: an NFT marketplace featuring on-chain staking and real-world utility, and SmartCommerce—a platform where users spend NTE tokens on digital and physical products.

We are seeking an experienced Solidity developer to design and implement the core smart contracts for these two products. What you will build

• NFT minting, listing, and trading contracts (BEP-721/BEP-1155)
• Staking logic — reward calculation per second, lock-up periods, secure withdrawal flows
• On-chain payment contracts for SmartCommerce
• Comprehensive test suites (unit, integration, fuzz testing)
• Contract preparation for third-party security audits

Requirements

• 2+ years of experience writing Solidity for production
• Contracts deployed and verified on BscScan or Etherscan (please provide links — this counts for more than a resume)
• Solid understanding of vulnerabilities: reentrancy, integer overflow, oracle manipulation, front-running
• Experience with Hardhat or Foundry
• Familiarity with OpenZeppelin contracts and EVM token standards

Bonus points

• Prior experience with staking protocols or NFT marketplaces
• Experience undergoing third-party audits (CertiK, PeckShield, etc.)
• Familiarity with IPFS/Arweave
• Full-stack blockchain developers with strong Solidity skills are welcome

Details

• Type: Remote, full-time
• Compensation: USD $52,000 – $58,000/year (negotiable based on experience)
• Hiring process: Portfolio review → 1-hour practical assessment (hands-on project, no LeetCode) → technical interview (20–30 min) → final interview → offer
