About the Role

Our client, a pioneering force in Decentralized Finance (DeFi), is seeking an exceptionally talented and motivated Remote Blockchain Developer with a specialization in DeFi protocols. This role is entirely remote, offering the flexibility to work from anywhere within South Africa, though it's an excellent opportunity for individuals residing near **Mossel Bay, Western Cape**. You will be at the forefront of developing and optimizing innovative DeFi applications, including decentralized exchanges (DEXs), lending protocols, and yield farming platforms. This is a chance to contribute significantly to the growth of a leading DeFi ecosystem, working with a passionate and distributed team. If you have a deep understanding of blockchain technology and a proven track record in building robust DeFi solutions, we want to hear from you.

Key Responsibilities

• Design, develop, test, and deploy smart contracts for various DeFi applications (e.g., AMMs, lending protocols, derivatives).
• Develop and maintain backend services and APIs to support DeFi applications.
• Integrate smart contracts with external data sources (oracles) and other blockchain protocols.
• Write clean, efficient, and secure Solidity code, focusing on gas optimization.
• Conduct rigorous testing, including unit, integration, and end-to-end testing of DeFi protocols.
• Collaborate with frontend developers to integrate smart contracts with user interfaces.
• Stay updated with the latest trends, innovations, and security best practices in the DeFi space.
• Participate in code reviews and contribute to the improvement of development processes.
• Troubleshoot and resolve issues in production smart contracts and applications.
• Contribute to technical documentation and knowledge sharing within the team.

Requirements

• Bachelor's degree in Computer Science, Software Engineering, or a related technical field, or equivalent practical experience.
• 3-5 years of experience in blockchain development, with a strong focus on DeFi.
• Proficiency in Solidity and experience with the Ethereum Virtual Machine (EVM).
• Proven experience building and deploying DeFi protocols (e.g., DEXs, lending platforms, staking contracts).
• Familiarity with DeFi concepts such as liquidity pools, impermanent loss, yield farming, and token standards (ERC-20, ERC-721).
• Experience with blockchain development tools and frameworks (e.g., Hardhat, Truffle, Foundry).
• Understanding of tokenomics and economic incentives within DeFi protocols.
• Knowledge of security best practices for smart contracts and DeFi applications.
• Experience with backend development (e.g., Node.js, Python) and RESTful APIs.
• Excellent problem-solving skills and the ability to work independently in a remote setting.
• Strong communication skills for effective collaboration with a distributed team.
• While this is a remote role, proximity to **Mossel Bay, Western Cape** is a plus but not required.

Benefits

• Highly competitive salary and performance-based incentives.
• Fully remote work environment with flexible hours.
• Comprehensive health and wellness benefits.
• Generous budget for professional development, conferences, and online courses.
