Smart Contract Engineer at Layer N

Job Description

Key Responsibilities

• Architect and implement smart contract solutions for decentralized applications (dApps), focusing on core functionalities such as token management, governance mechanisms, and decentralized finance (DeFi) protocols.
• Write, test, debug, and deploy smart contracts on blockchain platforms like Ethereum, ensuring robustness, security, and compliance with regulatory requirements.
• Optimize contract performance and gas efficiency to reduce transaction costs and improve scalability, leveraging tools like Hardhat or Truffle for development and testing.
• Collaborate with developers, product managers, and QA teams to define specifications, integrate contracts into larger systems, and ensure seamless user experiences.
• Contribute to the maintenance and enhancement of an open-source project, including code reviews, documentation updates, and community engagement to promote adoption and transparency.
• Monitor and analyze contract behavior post-deployment, identifying potential vulnerabilities or bugs and implementing timely fixes to ensure system reliability.
• Stay updated on emerging blockchain technologies, industry trends, and security threats to continuously refine development approaches and mitigate risks.

Job Requirements

• Proven experience (5+ years) in smart contract development, with a strong portfolio of production-grade Solidity projects deployed on major blockchain networks.
• Advanced proficiency in Solidity, including mastery of contract patterns, security best practices (e.g., reentrancy guards, access control), and gas optimization techniques.
• Deep understanding of blockchain architecture, consensus mechanisms, and cryptographic principles, with hands-on experience in Ethereum or other EVM-compatible platforms.
• Excellent problem-solving skills and ability to debug complex issues under time constraints, supported by familiarity with testing frameworks like Mocha or Chai.
• Strong collaboration and communication abilities to work effectively with distributed teams, present technical solutions to non-technical stakeholders, and document processes for maintainability.
• Experience with version control systems (e.g., Git) and agile development methodologies, including Scrum or Kanban, to manage project timelines and deliverables.
• Preferred qualifications include a degree in Computer Science, Software Engineering, or a related field, along with knowledge of decentralized identity (DID), NFTs, or DAO frameworks.
• Ability to mentor junior engineers, conduct code reviews, and contribute to the design of scalable, secure, and user-friendly blockchain systems.

This role is ideal for a seasoned developer passionate about blockchain innovation, with a proven track record of delivering high-impact smart contract solutions. You will work in a dynamic environment that values technical leadership, open-source contributions, and continuous learning. The position offers opportunities to shape the future of decentralized technologies while collaborating with industry experts and contributing to a globally recognized project.
