About Legal Chain
At Legal Chain, we’re reengineering how the world interacts with law. By merging AI and Web3, we’re creating a decentralized legal ecosystem that automates document management, contract intelligence, and compliance — all backed by blockchain transparency, security, and immutability. Our mission: build the trust layer for legal data in a digital-first world.
Blockchain Role Overview
We’re looking for a Blockchain / Web3 Developer with deep Ethereum expertise to help architect and deploy smart contract systems that make legal documents verifiable, permanent, and secure. You’ll be shaping the decentralized foundation of a next-generation AI-powered LegalTech platform — one block at a time.
This is an equity-based remote role (U.S. only) designed for builders who want to code the legal infrastructure of the future.
What You’ll Build
- Design & deploy Solidity smart contracts for authentication, timestamping, and proof-of-ownership.
- Integrate Web3 protocols directly into Legal Chain’s AI-driven document platform.
- Optimize blockchain performance using Layer 2 networks (Polygon, Arbitrum, Optimism) for speed and gas efficiency.
- Collaborate cross-functionally with AI engineers, legal experts, and product teams to bridge law and code.
- Implement decentralized storage via IPFS, Arweave, or Filecoin for immutable document storage.
- Maintain high-grade security standards across contract deployment, audits, and node operations.
What You Bring
- Strong command of Solidity, EVM internals, and Ethereum development frameworks (Hardhat, Foundry, Truffle).
- Experience with web3.js, ethers.js, Node.js, and API integration.
- Working knowledge of cryptography, Merkle proofs, and data verification models.
- Familiarity with decentralized storage systems and smart contract security patterns.
- Startup or early-stage experience where you’ve built and shipped code that scales.
- Must be legally authorized to work in the United States.
Why Build with Us
- Join a mission-first startup shaping how law meets blockchain.
- Lead innovation in AI × Web3 infrastructure for the legal world.
- Remote-first, builder-friendly environment focused on creativity and ownership.
- Equity-based opportunity with room to grow into a lead or founding-engineer role.
Must be authorized to work in the United States: Due to the nature of our operations, this position is open exclusively to those located in the United States.
