Web3 Architect

Role & responsibilities

• Lead the architecture, design, and implementation of enterprise Web3 and blockchain solutions.
• Define scalable, secure, and high-performance blockchain architecture, protocols, platforms, and integration patterns.
• Evaluate blockchain networks and technologies including Ethereum, EVM-compatible chains, Layer 1/Layer 2 networks, Solana, and enterprise DLT platforms.
• Design and oversee development of smart contracts, decentralized applications (dApps), tokenization platforms, digital asset solutions, DeFi applications, and Web3 infrastructure.
• Translate business and product requirements into technical architecture, solution blueprints, APIs, data models, and implementation roadmaps.
• Design smart-contract architecture and blockchain integrations using Solidity, Rust, Go, or relevant technologies.
• Establish standards for smart-contract security, blockchain security, cryptography, key management, wallet security, and transaction integrity.
• Architect cross-chain interoperability, blockchain bridges, oracles, decentralized storage, and blockchain data solutions where required.
• Design integrations between blockchain networks and enterprise systems, APIs, databases, payment platforms, cloud infrastructure, and external services.
• Drive scalability, performance, availability, gas optimization, transaction throughput, and infrastructure cost optimization.
• Lead technical POCs and evaluate emerging technologies such as Zero-Knowledge Proofs, zk-Rollups, Account Abstraction, tokenization, and decentralized identity.
• Collaborate with product managers, blockchain developers, security teams, cloud engineers, compliance teams, and business stakeholders.
• Conduct architecture reviews, technical assessments, code/design reviews, and technology/vendor evaluations.
• Establish best practices for DevOps, CI/CD, monitoring, observability, testing, deployment, and blockchain infrastructure management.
• Ensure Web3 solutions comply with applicable security, regulatory, privacy, AML/KYC, and digital-asset governance requirements.
• Mentor blockchain engineers and provide technical leadership across Web3 development teams.
• Communicate architecture decisions, technical risks, investment requirements, and implementation plans to senior management and stakeholders.
