• Web3 API Development: Design, develop, and maintain server-side logic and public APIs using TypeScript, SQL, REST, GraphQL, and Web Sockets.
• Optimization & Scalability: Write efficient, reusable, and reliable code to optimize for maximum speed, scalability, and system efficiency.
• Tooling & Integration: Apply knowledge of Solidity and the EVM transaction lifecycle to explore and unblock Web3 tool and DApp integration capabilities, ensuring developers can use familiar tools.
• Innovation: Continuously discover, evaluate, and implement new technologies to maximize development efficiency and effectiveness.
• Experience: 7+ years of software development experience, with experience in distributed open-source application development.
• EVM Expertise: Deep knowledge of the blockchain technology ecosystem, particularly the EVM, including understanding of ERC20s, ERC721s, and other on/off-chain standards.

Smart Contract Development: Experience with smart-contract development (Solidity/Vyper), using popular frameworks like Foundry, Hardhat, Web3.js / Ethers.js, and writing secure, efficient, and gas-optimized smart contracts.

• Language Expertise: Expertise in the Java and JS/TS programming languages and their ecosystems.

API & Integration: Strong understanding of RESTful API design and development, and experience with Wallet integrations (MetaMask, WalletConnect, etc.). Development Process: Familiarity with test-driven software development processes and continuous integration tools. Tooling: Experience with Web3 tools that support development, indexing, and transaction management (e.g., TheGraph). Education: Master’s degree in Computer Science or a similar field, or equivalent work experience. Soft Skills: Excellent debugging, critical thinking, and interpersonal skills.

Preferred Experience (Nice-to-Haves):

• Deep knowledge of and experience with the Java VM and Node.js VM (5+ years of experience in each).
• Strong grasp of Computer Science fundamentals, including concurrency and performance optimization.
• Familiarity with security principles, cryptographic tools, and high-performance architectural systems.
• Compensation: Highly competitive package including Equity & Tokens.
• Bonus: Opportunities for Performance Bonuses.
• US Benefits: Health insurance and 401k for US employees only.
