We are looking for a AI Web3 Backend Engineer with deep expertise in DeFi protocols , backend engineering , and agentic architectures . 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

Architect and implement the Traia.io AI Agent Marketplace backend and deployment infrastructure.
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.
Collaborate with researchers, smart contract engineers, and AI experts to shape AI-on-chain standards .

REQUIREMENTS

Backend engineering expertise : strong experience in designing and deploying distributed systems.
Agentic architectures : familiarity with multi-agent systems, MCP servers, A2A protocol, and autonomous workflow orchestration.
Solid knowledge of deployment architectures for agent-based systems (Docker, Kubernetes, enclaves, secure containerization).
Familiarity with RAG pipelines or AI-enhanced decision-making.
Web3 development background : smart contracts (Solidity/Rust), DeFi protocol integrations, on-chain settlement logic.
Strong ability to reason about security, decentralization, and performance tradeoffs .

What We Offer

The chance to build foundational infrastructure for the AI x Web3 ecosystem.
Work on cutting-edge multi-agent frameworks and verification systems.
A highly collaborative environment of engineers, researchers, and builders pushing the frontier.
Remote-first culture with flexible collaboration.
