Remote | Full time

Compensation: $200K - $300K

We are hiring on behalf of our client, a pioneering technology company tackling one of the most critical challenges today: unlocking the immense power of private data without compromising privacy. They are building the AI-native data platform that allows major industries—from finance and energy to supply chain and construction—to securely analyze and act on their most sensitive information.

This is your opportunity to work at the intersection of privacy, big data, and artificial intelligence. You won't just be writing code; you'll be creating the foundational tools that enable companies to make smarter, data-driven decisions. If you're passionate about solving complex problems and want to have a tangible impact on how data is used intelligently and ethically, join them and help define the next generation of AI.

They are hiring a Solidity Engineer to build the core smart contract infrastructure for a tokenized data exchange powering enterprise-grade AI and analytics workflows.

Key Responsibilities:

• 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 and custom access control (e.g., ERC-5006).
• Pricing modules (fixed, dynamic, oracles, AMM-style models).
• Design and implement smart contracts that enable data discovery, licensing, and pricing—on-chain. These modules will be inspired by DEXs, NFT marketplaces, and perp-style financial infrastructure, adapted for the unique constraints of enterprise data.
• Integrate with the Layer 1 settlement layer and bridge infrastructure.
• Write modular, gas-optimized, secure, and auditable Solidity code.
• Write comprehensive test suites using Hardhat, Foundry, or similar frameworks.
• Collaborate with frontend/backend, protocol, and enterprise teams to align smart contracts with user needs.
• Participate in contract audits, upgrades, and mainnet deployments.

Requirements

• 3+ years of experience building Solidity contracts for production applications.
• Deep familiarity with EVM mechanics: storage layout, events, proxy patterns, and calldata management.
• Hands-on experience with DEXs, NFT exchanges, or perp-style trading systems.
• Strong understanding of pricing mechanisms (e.g., oracles, TWAPs, bonding curves, auctions, etc.).
• Proficient with development tools like Hardhat, Foundry, or Brownie, and strong Git-based workflows.
• 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.

What They Offer:

Impact: Help define the on-chain standard and novel use cases for enterprise data exchange, access control, and data pricing.

Team: Work with a cross-disciplinary team spanning blockchain, AI, and traditional enterprise systems.

Compensation: Highly competitive Base Salary + Tokens/Equity package.

Backing: Join a company backed by top-tier investors and strong enterprise design partners.
