Company Overview
We are the founding team of an industry-leading DeFi project that has garnered significant attention and investment from top-tier institutions in Silicon Valley and the cryptocurrency space. Our mission is to innovate and deliver cutting-edge decentralized financial solutions that redefine traditional finance through blockchain technology. As a core member of this dynamic team, we seek a senior smart contract engineer to contribute to our ongoing development and ensure the robustness of our DeFi ecosystem.
Job Description
The senior smart contract engineer will play a pivotal role in shaping the technical foundation of our DeFi products. This includes designing, developing, and deploying secure, efficient, and scalable smart contracts on the Ethereum Virtual Machine (EVM). You will work closely with cross-functional teams to integrate these contracts seamlessly with user interfaces, backend systems, and other critical components of our platform. Additionally, you will be responsible for creating comprehensive test plans and use cases to validate the reliability, security, and performance of our smart contract infrastructure. The role also involves staying abreast of the latest advancements in blockchain technology, Ethereum upgrades, and best practices in smart contract development to ensure our solutions remain competitive and future-proof.
Key Responsibilities
- Architect and implement secure, auditable, and high-performance smart contracts for DeFi protocols, ensuring compliance with industry standards and regulatory requirements.
- Collaborate with product managers, designers, and developers to translate business requirements into technical specifications for smart contract functionality.
- Conduct rigorous code audits on existing contracts, identify vulnerabilities, and propose optimization strategies to enhance security and efficiency.
- Develop and maintain automated testing frameworks using tools like Truffle, Hardhat, or Mocha to ensure contract reliability under various scenarios.
- Participate in the design and implementation of decentralized applications (dApps) that leverage smart contracts for lending, borrowing, trading, or yield generation.
- Document contract logic, interactions, and security measures to facilitate onboarding of new team members and future maintenance efforts.
- Engage in continuous learning and experimentation with emerging blockchain technologies, cross-chain solutions, and novel DeFi use cases.
- Coordinate with external auditors and security experts to ensure third-party validation of critical smart contract components.
- Monitor and analyze blockchain network performance metrics to optimize gas costs and transaction throughput for our contracts.
- Lead technical discussions and contribute to the strategic direction of our DeFi product roadmap through innovative contract design.
Job Requirements
- Proven expertise in blockchain development with a minimum of 5 years of experience in designing and deploying smart contracts on Ethereum and other EVM-compatible chains.
- Advanced proficiency in Solidity (v0.8.x preferred), including mastery of security patterns, gas optimization techniques, and contract best practices.
- Strong understanding of DeFi protocols, including lending, stablecoins, yield farming, and decentralized exchanges, with hands-on experience in at least two of these domains.
- Experience with blockchain development tools such as Truffle, Hardhat, Remix, and Ethers.js, along with version control systems like Git.
- Ability to conduct thorough security audits using frameworks like OpenZeppelin, Slither, or MythX, and demonstrate a track record of identifying and mitigating vulnerabilities.
- Excellent problem-solving skills and a deep technical understanding of cryptographic principles, consensus mechanisms, and blockchain architecture.
- Collaborative mindset with proven experience in working within agile development teams and cross-functional collaboration environments.
- Strong communication skills to effectively convey technical concepts to non-technical stakeholders and document complex contract logic.
- Preferred: Experience with cross-chain bridges, zero-knowledge proofs, or other advanced blockchain technologies that enable innovative DeFi solutions.
- Preferred: Familiarity with DeFi governance models, on-chain analytics tools, and regulatory compliance frameworks for blockchain projects.
