Job Description
As a Golang backend engineer, you will be responsible for designing, developing, and maintaining the core backend systems for decentralized applications (DAPPs) within a blockchain ecosystem. This role requires deep technical expertise in building scalable, secure, and high-performance infrastructure that supports complex decentralized protocols and user-facing services. You will collaborate with cross-functional teams to deliver robust solutions that integrate with Ethereum, EVM-based networks, and other layer 1 and 2 blockchain technologies. The position involves working on cutting-edge projects related to NFT marketplaces, decentralized finance (DeFi), and gamefi platforms, ensuring seamless interaction between smart contracts and backend systems.
Key Responsibilities
- Develop and maintain backend services for DAPPs, focusing on performance optimization, security enhancements, and system scalability.
- Design and implement APIs for blockchain-based applications, ensuring compatibility with Ethereum, EVM, and other layer 1/2 protocols.
- Collaborate with blockchain developers to integrate smart contracts with backend systems, handling transaction processing, data validation, and state management.
- Conduct code reviews, debug complex issues, and ensure adherence to best practices in Go development and blockchain architecture.
- Research and adopt new technologies, tools, and frameworks to improve system efficiency and support emerging blockchain use cases.
- Document technical specifications, maintain system architecture diagrams, and provide clear explanations for backend components.
- Work closely with product managers and frontend teams to align development efforts with business goals and user requirements.
- Monitor system performance, identify bottlenecks, and implement solutions to ensure reliability and uptime for decentralized applications.
- Participate in agile development cycles, including sprint planning, daily standups, and iterative delivery of backend features.
- Ensure compliance with security standards, such as preventing smart contract vulnerabilities, protecting user data, and maintaining network integrity.
Job Requirements
- Proficient in Golang, with 3+ years of experience building scalable backend systems for blockchain applications.
- Deep understanding of Ethereum blockchain, Solidity smart contracts, and EVM execution environment.
- Experience with layer 1 and layer 2 blockchain technologies, including but not limited to IPFS, Cosmos, and Polygon.
- Strong knowledge of API development, RESTful services, and GraphQL integration for decentralized platforms.
- Hands-on experience with blockchain tools such as Truffle, Hardhat, and Remix for contract deployment and testing.
- Excellent problem-solving skills and ability to debug complex issues in distributed systems and blockchain networks.
- Experience with NFT marketplaces, DeFi protocols, and GameFi applications, including token economics and smart contract logic.
- Proficiency in version control systems like Git, and experience with CI/CD pipelines for automated testing and deployment.
- Ability to work in a fast-paced environment, prioritize tasks effectively, and deliver high-quality code under tight deadlines.
- Strong communication skills to collaborate with developers, stakeholders, and cross-functional teams on technical challenges.
- Knowledge of cloud platforms (AWS, GCP, Azure) and containerization technologies (Docker, Kubernetes) for scalable deployment.
- Experience with blockchain analytics tools and familiarity with on-chain data processing for application insights.
- Understanding of decentralized application security best practices, including cryptographic protocols and access control mechanisms.
- Ability to design and implement backend systems that support high-throughput transactions and low-latency responses for blockchain applications.
- Experience with blockchain consensus algorithms and network protocols to ensure system reliability and consensus integrity.
- Knowledge of blockchain scalability solutions such as sharding, state channels, and layer 2 rollups.
- Strong analytical skills to evaluate system performance, identify optimization opportunities, and implement improvements.
- Ability to document technical processes, maintain system architecture, and provide clear guidance for team members.
- Experience with blockchain-based application testing, including unit testing, integration testing, and stress testing for decentralized systems.
