• Collaborate with product managers, software engineers, designers, and business stakeholders throughout the development lifecycle.
• Define technical architecture, system components, blockchain protocols, and integration strategies.
• Evaluate blockchain networks and select suitable platforms based on project requirements.
• Work with Ethereum and other compatible Layer 1 and Layer 2 blockchain ecosystems.
• Develop and integrate smart contracts with web applications, APIs, wallets, and backend services.
• Design token-based systems, digital assets, and blockchain transaction workflows where applicable.
• Implement contract standards such as ERC-20, ERC-721, ERC-1155, and other relevant protocols.
• Conduct smart contract testing, debugging, optimization, and deployment across development and production environments.
• Perform code reviews and identify potential security, performance, and architectural issues.
• Work closely with cybersecurity teams to strengthen blockchain application security.
• Identify vulnerabilities such as reentrancy, access-control issues, integer-related vulnerabilities, oracle manipulation, and other smart contract risks.
• Support smart contract audits and address findings identified through security assessments.
• Optimize smart contract code for gas efficiency, transaction performance, and maintainability.
• Design secure wallet, key-management, authentication, and transaction-signing workflows.
• Integrate blockchain solutions with existing enterprise systems, databases, APIs, and cloud environments.
• Develop blockchain integration patterns for financial, supply-chain, identity, asset-management, or other business applications.
• Evaluate decentralized protocols, infrastructure providers, blockchain frameworks, and development tools.
• Monitor blockchain technology developments and assess emerging protocols and architectures.
• Research Layer 2 solutions, interoperability technologies, decentralized storage, oracles, and cross-chain technologies.
• Prepare technical architecture documents, system diagrams, API specifications, and smart contract documentation.
• Establish development standards, coding practices, testing procedures, and deployment processes for blockchain projects.
• Support CI/CD pipelines and automated testing for blockchain applications and smart contracts.
• Troubleshoot blockchain transactions, contract failures, integration issues, and production incidents.
• Work with external blockchain vendors, infrastructure providers, auditors, and technology partners when required.
• Provide technical guidance and mentorship to developers working on blockchain projects.
• Ensure blockchain solutions are designed with appropriate governance, monitoring, compliance, and operational controls.
