At Ironclad Ledger, we're pioneering enterprise blockchain solutions that bridge cutting-edge technology with real-world business applications. We develop multiple projects across the Ethereum ecosystem and EVM-compatible chains, solving complex challenges in supply chain, compliance, and enterprise automation.

We’re expanding our development team and seeking a Senior Full‑Stack Web3 Developer who excels at building intuitive decentralized applications that integrate seamlessly with our smart contracts. In this role, you’ll own the front‑end and integration layers, working closely with our Solidity engineers to deliver polished, reliable dApps. If you thrive in a fast-paced environment and enjoy owning the full stack from UI to chain interaction, join us.

Responsibilities

• Design, build, and maintain full‑stack dApps with modern frameworks (React/Next.js).
• Integrate wallet connections and blockchain interactions using ethers.js, viem, wagmi, or web3.js.
• Work with decentralized storage (IPFS, Filecoin, Arweave, Pinata) for off‑chain metadata and content.
• Write unit/integration tests for both front‑end components and contract interaction logic.
• Collaborate with smart contract engineers to define clean interfaces and optimize gas‑efficient front‑end patterns.
• Maintain deployment pipelines and monitor production dApps.

Job Requirements

• 4+ years of full‑stack development, with at least 2 years focused on Web3.
• Deep, hands‑on experience with ethers.js, viem/wagmi, or web3.js.
• Strong TypeScript/JavaScript and component‑based frameworks (React/Next.js preferred).
• Proven knowledge of IPFS, Filecoin, Arweave, or similar decentralized storage protocols.
• Solid understanding of smart contract interactions (ABIs, encoding/decoding, gas estimation, event listening).
• Experience with Node.js backends or serverless functions.
• Clear communication and ability to work autonomously in a remote, async environment.

Bonus Skills

• Solidity experience – you’ve written, tested, or audited simple contracts.
• Familiarity with Hardhat or Foundry (useful for testing local forks).
• Experience with multiple EVM chains (Ethereum, Polygon, Arbitrum, Base, Optimism).
• Knowledge of token standards (ERC‑20, ERC‑721, ERC‑1155) and integration patterns.
• Experience with The Graph (subgraphs) or GraphQL.

Why Work With Us?

• Diverse Enterprise Projects: Work on supply chain tracking, compliance automation, and DeFi tools for real clients.
• Direct Impact: Your code ships to production and solves tangible business problems.
• Flexible Commitment: Full‑time or contract (20–40 hours/week) – you choose.
• Competitive Compensation: $60–$120 per hour (contract) or competitive salary (full-time), commensurate with experience.
• Remote‑First, Async‑Friendly: Work from anywhere, manage your own schedule.

Ready to Build?

If you’re passionate about Web3 and enjoy owning the full stack from UI to chain, please apply with your resume, GitHub/portfolio, and a short note about a dApp you built (and which Web3 library you chose – and why).
