Blockchain Architect

Role & responsibilities

• Design and implement scalable, secure, and high-performance blockchain architectures aligned with business and technical requirements.
• Evaluate and select suitable blockchain platforms, protocols, consensus mechanisms, and distributed ledger technologies for enterprise use cases.
• Architect and develop smart contracts, decentralized applications (dApps), and blockchain-based solutions using platforms such as Ethereum and Hyperledger Fabric.
• Define blockchain network architecture, including public, private, and consortium blockchain networks.
• Lead smart contract development, testing, deployment, auditing, and optimization to ensure security and reliability.
• Design tokenization frameworks, digital asset solutions, and blockchain-based transaction workflows where applicable.
• Integrate blockchain applications with enterprise systems, databases, APIs, payment platforms, and external services.
• Establish blockchain security standards covering cryptography, identity management, access controls, key management, and transaction validation.
• Optimize blockchain performance, scalability, interoperability, transaction throughput, and network costs.
• Evaluate Layer 1 and Layer 2 solutions, cross-chain interoperability, bridges, and decentralized infrastructure.
• Collaborate with product managers, developers, security teams, business stakeholders, and compliance teams to translate requirements into technical architecture.
• Define architecture standards, development guidelines, technical documentation, and governance practices.
• Lead proof-of-concept initiatives, technical design reviews, architecture assessments, and production deployments.
• Monitor emerging blockchain technologies, Web3 developments, and industry standards to identify opportunities for innovation.
• Provide technical leadership, mentor engineering teams, and ensure compliance with applicable security and regulatory requirements.

Preferred candidate profile
