skill: 5+ years building scalable, high-performance backend systems. Deep understanding of software engineering best-practices and architectures. In-depth hands-on experience designing decentralized applications and protocols (asymmetric cryptography, hashing algorithms, Merkle trees, peer-to-peer networking, consensus mechanisms, token economics, and smart contracts). Strong written and verbal communication skills, ability to debate complex technical tradeoffs, and debug complicated issues across protocol layers with globally distributed engineering teams. 加分项： Experience with machine learning platforms - knowledge of ML models, pipelines, MLOps tools or a strong desire to learn these technologies. Startup or early-stage company experience showing scrappiness, resilience, and comfort with ambiguity. Hands-on experience with zkRollups, Optimistic Rollups, trusted execution environments (TEEs), cross-chain bridges. 职责： Collaborate on high-level architecture and protocols for a novel AI/blockchain system. Research and evaluate technology options for key components like on-chain coordination, storage, and secure compute. Design core system functionality end-to-end, documenting in technical specifications and whitepaper. Implement smart contract logic and off-chain components required for minimum viable product. Work closely with founding team to iteratively refine architecture and roadmap based on learnings.
