You will play a pivotal role in designing and building the marketplace of AI agents, enabling them to collaborate, execute multi-agent workflows, and securely manage funds on-chain.This role requires someone who is as comfortable deploying large-scale backend systems as they are with smart contract engineering and the next-gen agent-to-agent (A2A) protocols that power AI-native Web3 applications.Key Responsibilities

  • Build and maintain multi-agent workflows: utility agents, solver agents, settlement agents, etc.
  • Integrate MCP servers, A2A protocols, and on-chain execution environments.
  • Develop secure agent deployment principles (sandboxing, containerization, notarization).
  • Implement DeFi trading strategies through on-chain agent logic and Web3 integrations.
  • Work with zk-systems and TLS notarizations to enable verifiable execution and trust guarantees.
  • Collaborate with researchers, smart contract engineers, and AI experts to shape AI-on-chain standards.
Requirements

  • Solid knowledge of deployment architectures for agent-based systems (Docker, Kubernetes, enclaves, secure containerization).
  • Understanding of cryptography and verification systems (zk proofs, TLSNotary, EIP-1271-style validation).
  • Strong ability to reason about security, decentralization, and performance tradeoffs.
  • Bonus: familiarity with RAG pipelines or AI-enhanced decision-making.

What We Offer

  • Work on cutting-edge multi-agent frameworks and verification systems.
