Staff Software Engineer - Smart Contracts Team

🔗 Senior EVM & Web3 Engineer - Enterprise Distributed Ledger

Location: Remote - US - Open to Europe if happy to overlap with EST

Compensation: Competitive

We are a fast-growing software company dedicated to supporting and servicing an open source, proof-of-stake platform that is EVM-compatible. This network is specifically built to meet the needs of enterprise and Web3 applications, prioritizing speed, security, and stability. We are seeking a seasoned Smart Contract Engineer to join our team, focusing on developing both the core Java services and the Web3 APIs (JS/TS) that process transactions across our network.

You will be a high-impact, hands-on programmer, spending approximately 80% of your time designing, coding, and testing. Your primary focus will be enhancing EVM compatibility and improving the developer experience (DevEx) for users migrating from other EVM chains. This includes both low-level transaction processing in Java and high-level API development for public consumption.

Key Responsibilities:

• EVM Compatibility & DevEx: Stay connected with the EVM ecosystem, bringing vital learnings and applicable explorations back to the team to improve EVM DevEx.
• Core Service Enhancement: Implement and enhance the Java-based smart contract services that parse bytecode and process transactions submitted via an EVM client.
• 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.
