We are hiring directly for our internal development team. This is not a recruitment agency posting - we are the direct employer looking for a core team member to build our flagship Web3 product.
We are developing an innovative decentralized platform and need a Lead Blockchain Developer to take complete ownership of our smart contract architecture, NFT minting mechanisms, marketplace logic, and wallet integrations. You will work side-by-side with our founding engineers, not as an outsourced vendor, but as a key decision-maker in our in-house tech stack.
Key Responsibilities:
Architect, develop, test, and deploy Solidity smart contracts on EVM-compatible blockchains.
Build and customize ERC-721 and ERC-1155 NFT contracts, including logic for ownership verification and reward distribution.
Seamlessly connect smart contracts with our Node.js/Express backend and React/Next.js frontend using Web3.js or Ethers.js.
Write comprehensive automated tests using Hardhat, Truffle, or Foundry, and manage deployments across testnet and mainnet.
Create and maintain clear technical documentation for all smart contracts and on-chain processes.
Required Qualifications:
Minimum 5 years of blockchain-specific experience, with at least 8 years in software development overall.
Proven track record of shipping production-grade Solidity contracts (ERC-721, ERC-1155, ERC-20).
Deep proficiency with Hardhat, Truffle, or Foundry for testing and deployment workflows.
Solid experience integrating blockchain logic with Node.js backends via REST APIs and event-driven architectures.
Strong analytical mindset and excellent written/verbal communication skills.
Preferred Qualifications:
Experience building NFT marketplaces, royalty platforms, or collaborative Web3 products.
Active participation in open-source blockchain communities or projects.
Why join us directly?
You will have direct equity/ownership discussions with the founders, zero middlemen, and full creative control over the blockchain layer. We are looking for a long-term technical partner, not a one-off contractor.
To apply: Please send your GitHub/portfolio and resume directly through Hubstaff. No agencies, recruiters, or third-party intermediaries, please.
