Full-timeInformation Technology
As Web3 Architect, you will be responsible for defining and shaping the overall technical strategy for blockchain-based systems. You will lead architectural design, tooling decisions, protocol selection, and ensure secure, scalable, and interoperable solutions. You will work closely with other architects, engineering teams, product managers, and external partners to ensure we deliver cutting-edge Web3 products.

Key Responsibilities

  • Define system architectures for decentralised applications , smart contracts, blockchain networks, side-chains, layer-2 solutions and/or roll-ups.
  • Select appropriate blockchain protocols , consensus mechanisms, and scaling solutions based on use case.
  • Lead smart contract design and audit reviews to ensure security, gas optimisation, upgradeability, and best practices.
  • Design and integrate interoperable systems, bridges, or cross-chain communication where required.
  • Evaluate and adopt decentralised storage, identity, oracles, oracles, zero-knowledge proofs, and privacy enhancing technologies.
  • Oversee decentralised governance, tokenomics design, and incentive mechanisms in line with business objectives.
  • Define and enforce security, compliance, and regulatory best practices where applicable.
  • Guide tooling, CI/CD pipelines, developer SDKs, testing frameworks, and infrastructure required for Web3 deployment.
  • Mentor engineering teams to embed Web3 engineering culture and practices.
  • Monitor emerging developments in the Web3 / blockchain space and recommend adoption where beneficial.


Requirements

  • Strong experience (5+ years) in designing and delivering blockchain / decentralised solutions, smart contracts, or Web3 platforms.
  • Proficiency in one or more smart contract languages
  • Deep understanding of various blockchain architectures ,layer-2 (optimistic / zk-rollups), side-chains, sharding, and scalability trade-offs.
  • Familiarity with formal verification, gas profiling, security auditing, threat modelling.
  • Experience integrating and managing oracles, identity protocols (DID), privacy technologies
  • Strong software architecture skills: microservices, modular design, event-driven systems, API design.
  • Excellent understanding of cryptography fundamentals, consensus algorithms, distributed systems.
  • Skilled in infrastructure and operations: node operation, wallets, key management, deployment pipelines.
  • Good experience with cloud platforms and container orchestration (Docker, Kubernetes) is advantageous.
  • Excellent communication skills; able to explain complex technical topics to non-technical stakeholders and lead cross-disciplinary teams
