Solidity Engineer - On-Chain Data Exchange

Solidity Engineer - AI-Native Data Exchange

location: Remote - Must be based within PST -- CET Time zones

We are a pioneering technology company tackling one of the most critical challenges today: unlocking the immense power of private data without compromising privacy. We are building the AI-native data platform that allows major industries—from finance and energy to supply chain and construction—to securely analyse and act on their most sensitive information. This is your opportunity to work at the intersection of privacy, big data, and artificial intelligence. You will be creating the foundational tools that enable companies to make smarter, data-driven decisions and help define the next generation of AI.

We’re hiring a Solidity Engineer to build the core smart contract infrastructure for a tokenized data exchange powering enterprise-grade AI and analytics workflows. The ideal candidate has 2+ years of experience building in Solidity, strong familiarity with EVM-based applications, and deep comfort working with DeFi primitives.

You will:

• Design and implement smart contracts that enable data discovery, licensing, and pricing—on-chain.
• Develop modules inspired by decentralized exchanges (DEXs), NFT marketplaces, and perpetual-style financial infrastructure, adapted for the unique constraints of enterprise data.
• Architect and implement core contracts for the Data Exchange, including:
• On-chain orderbooks or matching logic.
• NFT-based data certificates (e.g., ERC-725, ERC-735).
• Licensing primitives (e.g., ERC-5006 / custom access control).
• Pricing modules (fixed, dynamic, oracles, AMM-style models).
• Integrate with L1 settlement layer and bridge infrastructure.
• Write modular, gas-optimized, and auditable Solidity code.
• Collaborate with frontend/backend, protocol, and enterprise teams to align smart contracts with user needs.
• Write comprehensive test suites using Hardhat, Foundry, or similar frameworks.
• Participate in contract audits, upgrades, and mainnet deployments.

Essential:

• Experience: 3+ years of experience building Solidity contracts for production applications.
• EVM Expertise: Deep familiarity with EVM mechanics: storage layout, events, proxy patterns, and calldata management.
• DeFi Knowledge: Hands-on experience with DEXs, NFT exchanges, or perp-style trading systems.
• Pricing Mechanisms: Strong understanding of pricing mechanisms (e.g., oracles, TWAPs, bonding curves, auctions, etc.).
• Tooling: Proficient with Hardhat, Foundry, or Brownie; strong Git-based workflows.
• Production History: Experience shipping audited smart contracts to mainnet (please include examples).

Nice to Have:

• Experience with advanced token standards: ERC-725, ERC-735, ERC-5006.
• Prior work on data licensing, data marketplaces, or enterprise analytics systems.
• Familiarity with gas optimizations, proxy upgrade patterns, and reentrancy mitigations.
• Open-source contributions or published research/code in Solidity or DeFi.
• Strong interest in bridging enterprise systems with on-chain infrastructure.
