About the Role

My Client is looking for a visionary and hands-on Tech Lead to join our fast-growing Web3 platform focused on creator monetization. In this high-impact, strategic role, you’ll take ownership of system design and technical architecture, working closely with the CTO and cross-functional stakeholders to deliver scalable, secure, and user-centric Web3 applications.

You will lead the selection and implementation of the right technologies for the business – from core infrastructure to application layer – with a strong focus on Layer 1 and Layer 2 blockchain integrations, smart contract development, and tokenomics.

Key Responsibilities

• Lead end-to-end system architecture and technical design of our Web3 platform.
• Evaluate and select appropriate Layer 1 and Layer 2 blockchain technologies based on product and business requirements.
• Design and oversee the development of smart contracts, ensuring security, auditability, and scalability.
• Collaborate with product, design, and marketing teams to translate user journeys into robust backend and frontend architecture.
• Guide technical implementation and mentor engineering teams where required.
• Ensure systems are secure, scalable, and optimized for performance in a distributed environment.
• Work closely with the CTO on technology strategy, roadmap planning, and scaling engineering efforts.
• Provide technical leadership during token generation events (TGEs) and contribute to the design and implementation of tokenomics models.

Requirements

• Proven experience as a Tech Lead, Solutions Architect, or Senior Engineer in a Web3 or blockchain environment.
• Strong hands-on experience in smart contract development (e.g. Solidity, Vyper), with a portfolio of deployed contracts.
• Deep understanding of blockchain fundamentals, particularly Layer 1 & Layer 2 protocols.
• Demonstrated experience in building and launching commercial-facing Web3 products to market.
• Solid understanding of tokenomics and direct involvement in at least one successful TGE or token launch.
• Strong grasp of system scalability, distributed infrastructure, and blockchain security best practices.
• Familiarity with modern cloud architecture (e.g. AWS/GCP) and containerized environments (e.g. Docker, Kubernetes) is a plus.
• Excellent communication skills and ability to collaborate with non-technical stakeholders.

Nice to Have

• Experience with DAO governance frameworks or staking mechanisms.
• Familiarity with zk-rollups, optimistic rollups, or other scaling solutions.
• Contributions to open-source blockchain projects or protocols.
