What is a Solidity engineer?

A Solidity Engineer is a blockchain developer specializing in writing smart contracts using Solidity, the primary programming language for Ethereum and other compatible blockchains. They design, develop, test, and deploy decentralized applications (dApps) and ensure contract security, performance, and efficiency. Solidity Engineers often work with tools like Hardhat, Truffle, and Web3.js to integrate smart contracts with front-end applications. Their role requires expertise in blockchain architecture, cryptography, and security best practices to prevent vulnerabilities like reentrancy attacks.

What does a Solidity engineer do?

A typical workday for a Solidity Engineer involves designing, coding, and testing smart contracts, collaborating closely with blockchain architects, front-end developers, and product managers. You may participate in code reviews, contribute to security audits, and stay updated on the latest Web3 technologies. Most teams work in an agile environment, which means frequent meetings to discuss progress and brainstorm solutions to technical challenges. This role offers the opportunity to tackle complex blockchain problems and contribute directly to innovative decentralized applications.

What are the key skills and qualifications needed to thrive as a Solidity engineer?

A Solidity Engineer requires strong proficiency in Solidity programming, blockchain concepts, and smart contract development, often supplemented by a degree in computer science or related fields. Familiarity with tools such as Truffle, Hardhat, Remix, and version control systems like Git is essential, while certifications like Certified Blockchain Developer can be advantageous. Attention to detail, problem-solving skills, and effective communication set outstanding candidates apart. These abilities are crucial to ensuring secure, efficient, and collaborative smart contract development in blockchain projects.

Job description

Interval helps enterprises turn messy, underused data into governed, high-confidence intelligence-without handing control to a black box. We bring compute to your data with a private data lakehouse, verifiable audit trails, and U-AI, our contextual AI framework for secure AI workflows.
Our platform is built around three outcomes:
- Control: Keep ownership of your data and how models use it.
- Verify: Audit what happened, why it happened, and where results came from.
- Monetize: Create new revenue opportunities through private, permissioned data exchange.
About the Role
We're looking for a Solidity Engineer with deep experience in smart contract development, particularly in designing complex data structures and logic for decentralized marketplaces. This role is critical to shaping the core primitives of Interval's on-chain data exchange, licensing systems, and dynamic pricing mechanisms.
You'll be working alongside world-class engineers, researchers, and product leaders to implement secure, scalable smart contracts that power the Interval protocol. We come from Chainlink, NEAR, LayerZero, Kraken, Coinbase, Point72, Curve, Twitter, and more.
Responsibilities
  • Design, implement, and test Solidity smart contracts for data tokenization, licensing, and pricing workflows.
  • Develop robust on-chain data structures to represent enterprise datasets, metadata, and access conditions.
  • Architect marketplace and exchange primitives including order books, escrow, dispute resolution, and royalties.
  • Integrate pricing logic grounded in financial derivatives (e.g., options pricing, bonding curves, auction models).
  • Optimize gas efficiency and ensure upgradability where needed using proxies or modular contracts.
  • Collaborate with auditors and internal security teams to harden contracts against vulnerabilities.
  • Work cross-functionally with product and protocol teams to define new features and mechanisms.

  • 3+ years of Solidity development experience with a strong portfolio of deployed smart contracts.
  • Proven understanding of EVM architecture, smart contract security, and gas optimization.
  • Experience building or contributing to Web3 exchanges, NFT marketplaces, or DeFi protocols.
  • Deep familiarity with data modeling, complex storage patterns, and Solidity-specific design patterns.
  • Knowledge of token standards (ERC20, ERC721, ERC1155, ERC4626) and upgradeable contract frameworks.
  • Exposure to pricing mechanisms, such as dynamic pricing curves, auctions, or option-like instruments.
  • Proficient in development tools (Hardhat, Foundry, Tenderly, etc.) and testing frameworks (Chai, Waffle).
  • Comfortable with Git-based workflows and agile engineering processes.

Bonus Qualifications
  • Background in quantitative finance, information theory, or data licensing models.
  • Experience with cross-chain messaging or bridging technologies.
  • Contributions to open-source projects in the Ethereum ecosystem.
  • Interest in AI workflows, data provenance, or zero-knowledge cryptography.
