Job description

As a Web3 backend developer, you'll be at the forefront of building the decentralized internet. Your primary focus will be on the server-side logic that powers decentralized applications (dApps), interacting with protocols, smart contracts, and decentralized storage systems. You'll be responsible for creating a robust and secure infrastructure that enables users to seamlessly interact with the Web3 ecosystem.

Responsibilities:

• Design and Development: Architecting, designing, and implementing efficient and scalable backend systems and APIs that connect to blockchain networks (e.g., Ethereum, Solana, Polygon).
• Smart Contract Interaction: Building and deploying serverless or decentralized backend services that interact with smart contracts.
• API Development: Creating secure and performant APIs for accessing blockchain and off-chain data.
• dApp Integration: Collaborating with frontend and blockchain developers to integrate backend services into new and existing dApps.
• Data Management: Designing and optimizing solutions for large-scale blockchain data storage, indexing, and querying.
• Security: Implementing security best practices to protect user data and prevent vulnerabilities in Web3 applications.
• Event Handling: Developing event-driven architectures to manage events triggered by smart contracts and blockchain transactions.
• Collaboration: Working closely with cross-functional teams (frontend, blockchain, product) to define and implement new features.
• Troubleshooting and Optimization: Identifying, debugging, and resolving performance and security issues in backend systems.
• Best Practices: Adhering to Web3 development standards, design patterns, and security guidelines.
• Documentation: Creating and maintaining technical documentation for backend components and processes.
• Continuous Learning: Staying up-to-date with the latest advancements in Web3 technologies, tools, and trends.

Key Skills and Qualifications:

• Blockchain Fundamentals: A strong understanding of blockchain technology, consensus mechanisms, cryptography, and decentralized protocols.
• Smart Contract Development: Proficiency in smart contract languages like Solidity, Vyper, or Rust, and experience with development frameworks (e.g., Truffle, Hardhat).
• Backend Development: Solid experience with backend programming languages (e.g., Node.js, Python, Go), database management, and API development (RESTful APIs).
• Web3 Technologies: Familiarity with Web3 libraries (e.g., Web3.js, Ethers.js), decentralized storage (e.g., IPFS), and relevant blockchain platforms (e.g., Ethereum, Solana).
• Cryptography: Knowledge of cryptographic concepts such as hashing, encryption, and digital signatures.
• Security: A strong understanding of security best practices in Web3 development, including common vulnerabilities and mitigation strategies.
• Cloud Technologies: Familiarity with cloud platforms (e.g., AWS, GCP) and serverless architectures.
• DevOps and CI/CD: Experience with tools like Docker, Kubernetes, and CI/CD pipelines for automated deployment.
• Problem-Solving: Strong analytical and problem-solving skills with the ability to debug and optimize complex systems.
• Collaboration: Excellent communication and teamwork skills to work effectively with cross-functional teams.
• Adaptability: Willingness to learn and adapt to the rapidly evolving Web3 landscape.
