• 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
