About the role

  • Design and implement core blockchain protocols with zkVM integration for verifiable AI agent execution
  • Define smart-contract standards and on-chain agent interfaces (analogous to EVM ABIs)
  • Build and optimize high-throughput, low-latency node software in Rust
  • Architect P2P networking, consensus mechanisms, and state synchronization tailored for AI workloads
  • Develop and audit smart contracts for agent registration, staking, and on-chain governance
  • Integrate multi-agent orchestration frameworks (e.g., CrewAI, MCP) into the blockchain runtime
  • Create backend services and APIs (REST/GraphQL) to interact with nodes and agents
  • Implement monitoring, observability, and analytics pipelines to track chain and agent performance
  • Partner with AI engineers to optimize gas models, transaction batching, and resource metering for agentic use cases
  • Research emerging Web3 and zero-knowledge technologies to keep our stack cutting-edge.

Requirements

  • 5+ years building or auditing blockchain protocols, smart contracts, or node infrastructure
  • Deep practical experience writing and maintaining large-scale Rust applications
  • Hands-on with zero-knowledge VM design or implementation (e.g., zkEVM, zkWASM)
  • Solidity or ink! proficiency; familiar with security best practices and gas optimization
  • Strong background in backend engineering (Node.js, Go, or Python)
  • In-depth understanding of consensus algorithms, P2P networking, and state replication
  • Proven track record working in decentralized environments; familiarity with staking, governance, token economics
  • Solid grasp of multi-agent systems, agent orchestration, or integrating AI workloads with on-chain logic
  • Nice-to-Haves: Experience with CrewAI, A2A protocols, or MCP server development
  • Familiarity with on-chain verifiable computation frameworks and trusted execution environments (TEEs)
  • Background in building RAG frameworks, vector search, or other AI-powered data services
  • Contributions to open-source blockchain or zero-knowledge projects
  • Thrives in ambiguous environments and independently drives solutions
  • Clearly articulates complex blockchain and AI topics to technical and non-technical stakeholders
  • Values teamwork and contributes to a culture of shared ownership
  • Passionate about staying current with Web3, ZK research, and AI advancements.
Benefits
  • Flexible work arrangements
  • Professional development opportunities
