Job Description
This position involves designing and developing backend API services for off-chain applications, as well as creating and maintaining smart contracts on the blockchain. The ideal candidate will work closely with cross-functional teams to ensure seamless integration and functionality across both on-chain and off-chain components. Responsibilities include writing, testing, and deploying APIs, developing secure and efficient smart contracts, and collaborating with developers and stakeholders to meet project goals.
Key Responsibilities
- Develop and maintain backend API services for off-chain applications, ensuring scalability, reliability, and performance.
- Design, implement, and deploy smart contracts on blockchain platforms such as Ethereum (EVM) and Rust-based systems.
- Collaborate with cross-functional teams to integrate on-chain and off-chain components effectively.
- Write and test smart contract code using Solidity, Rust, and other relevant languages.
- Optimize API performance and ensure secure, efficient, and compliant blockchain interactions.
- Participate in code reviews and contribute to the improvement of existing systems.
- Document technical specifications and maintain clear communication with stakeholders about project progress and challenges.
- Stay updated on blockchain technologies, industry trends, and best practices to enhance system capabilities.
- Debug and resolve complex technical issues across both backend and smart contract environments.
- Support the deployment and maintenance of blockchain-based solutions in production environments.
Job Requirements
- Proficient in backend development with experience in building APIs for off-chain applications (e.g., RESTful APIs, GraphQL interfaces).
- Strong knowledge of smart contract development, including Ethereum (EVM) and Rust-based frameworks (e.g., ink! or Substrate).
- Excellent understanding of blockchain platforms, tools, and protocols such as Solidity, Rust, and Ethereum Virtual Machine (EVM).
- Experience with version control systems like Git and collaborative development practices in agile environments.
- Excellent problem-solving skills and the ability to debug complex systems with high precision.
- Strong communication skills to collaborate with teams and stakeholders effectively.
- Ability to work independently and manage multiple tasks simultaneously under tight deadlines.
- Knowledge of cryptographic principles and security best practices for blockchain development.
- Experience with decentralized application (dApp) architecture and integration with front-end systems.
- Proficiency in programming languages such as Python, JavaScript, and Go for backend development.
- Understanding of blockchain consensus mechanisms and network protocols.
- Ability to analyze system requirements and translate them into technical solutions.
- Experience with DevOps tools and CI/CD pipelines for automated testing and deployment.
- Strong attention to detail and commitment to writing clean, maintainable code.
- Knowledge of blockchain scalability solutions and optimization techniques.
- Ability to work with stakeholders to define project scope and deliverables.
- Experience with blockchain analytics and monitoring tools for system performance evaluation.
- Proficiency in using blockchain development frameworks and libraries.
- Understanding of blockchain governance models and compliance requirements.
