Senior NFT Engineer

Senior NFT Engineer

About Us

We’re a mission-driven Web3 organization operating at the forefront of decentralized innovation. We believe blockchain technology has the power to fundamentally reshape the way people build, work, govern, and exchange value across the globe. Our work spans smart contracts, decentralized protocols, node networks, and data-driven blockchain tooling that empower individuals and communities.

We're a fast-paced, async-first, fully remote team made up of incredibly talented contractors around the world. Every day, we’re amazed by the creativity, integrity, and dedication of the people we work with — and we’re just getting started.

We believe in building with purpose, collaborating without ego, and shipping products that actually matter. If you're looking to do meaningful work in an environment that values autonomy, impact, and trust, you're in the right place.

Role Overview

We’re looking for a Senior NFT Developer who is passionate about building innovative, scalable, and secure NFT-based systems that redefine digital ownership and utility. You’ll lead the design and implementation of NFT smart contracts, on-chain metadata logic, and integrations with marketplaces, token standards, and off-chain services.

The ideal candidate has a proven track record of launching NFT projects — from generative collections and dynamic metadata to fractionalization, royalties, and advanced minting mechanics. You’re comfortable working across EVM-compatible chains, integrating with APIs and decentralized storage solutions (IPFS, Arweave), and ensuring top-tier security and performance at every step.

Key Responsibilities

• Architect, develop, and deploy secure NFT smart contracts using Solidity and ERC standards (ERC-721, ERC-1155, ERC-2981, etc.)
• Design custom minting logic, reveal mechanisms, and trait randomization systems for NFT collections
• Implement dynamic or evolving NFT metadata using decentralized storage (IPFS, Arweave, or Filecoin)
• Integrate NFTs into web3-enabled frontends and marketplaces using ethers.js, wagmi, or similar libraries
• Develop scalable minting, marketplace, and ownership verification APIs in collaboration with backend engineers
• Collaborate closely with product and design teams to translate creative and functional concepts into on-chain mechanics
• Conduct internal audits, write unit and integration tests using Hardhat or Foundry, and support external security reviews
• Optimize gas efficiency, minting performance, and cross-chain interoperability
• Stay current with NFT ecosystem standards, royalty models, and L2 minting best practices
• Contribute to open-source NFT tooling, SDKs, or developer documentation

Requirements

• 4+ years of experience developing and deploying Solidity smart contracts
• 2+ years specifically focused on NFTs or tokenized digital assets
• Deep understanding of NFT standards (ERC-721, ERC-1155, ERC-2981, ERC-6551) and their extensions
• Proven experience deploying NFT contracts to mainnet (Ethereum, Polygon, or comparable EVM chains)
• Familiarity with NFT marketplaces (OpenSea, Blur, Magic Eden) and on-chain indexing
• Strong grasp of metadata structures, decentralized storage, and token URI design
• Proficiency integrating smart contracts with backend or API services (Node.js, Go, or Python)
• Comfortable working in CI/CD environments, Git workflows, and async-first teams
• Excellent written communication and documentation skills for distributed collaboration
• Experience building or scaling NFT marketplaces, launchpads, or creator tools

Preferred Qualifications

• Hands-on experience with dynamic NFTs, gaming/NFT interoperability, or token-bound accounts (ERC-6551)
• Background in royalty enforcement, metadata evolution, or NFT rental/fractionalization mechanics
• Contributions to NFT open-source projects, SDKs, or community standards
• Familiarity with Layer 2 minting, bridging NFTs, or gasless transaction frameworks
• Prior involvement in NFT smart contract audits or bug bounty programs

Example Projects / Deliverables

Please include examples that demonstrate your NFT expertise, such as:

• Links to deployed NFT contracts (Etherscan, Polygonscan, etc.)
• Live NFT projects, marketplaces, or dApps you’ve developed or contributed to
• GitHub repositories or code samples of NFT-related Solidity contracts
• Whitepapers, design docs, or technical specifications you’ve authored
• Public audits or testnet deployments showing contract architecture and optimization

Hands-on experience with NFT smart contracts, metadata systems, and creative blockchain applications will be heavily weighted in our evaluation process.
