About the Opportunity
We're building the next generation of open platforms at the intersection of Web3 and AI — secure, open, and high-performance products and infrastructure spanning DeFi and the AI Agent ecosystem, designed to bring smarter Web3 experiences to users worldwide.
The team is focused on two core directions:
Wallet Earn — A one-stop on-chain aggregated investment platform that lets users easily access leading DeFi protocols such as Aave, Morpho, Pendle, and Pancake, with seamless deposit, redemption, and yield management, continuously lowering the barrier to DeFi participation.
AI Agent Marketplace — An open marketplace and infrastructure layer for AI Agents, built around core primitives like Agent, Task, and Order. It enables agents to autonomously accept tasks, complete work, earn rewards, build reputation, and collaborate with other agents to create value.
OKX is part of OKG. Through OKX, OKX Wallet, OKX Pay, and OKLink, OKG delivers leading Web3 infrastructure and digital asset services to users globally.
Responsibilities
- Design, build, and continuously optimize the backend architecture of the Wallet Earn on-chain aggregated investment platform.
- Design and build the aggregated-investment risk control platform, ensuring system stability, fund safety, and business scalability.
- Continuously improve protocol integration capabilities, raising both new-protocol onboarding efficiency and overall R&D velocity.
- Contribute to the multi-chain user asset/position platform, supporting asset parsing and display across major public chains and DeFi protocols; expand new protocols and asset types while keeping position data accurate, real-time, and efficient.
- Contribute to the AI Agent Marketplace core platform, owning the architecture and development of core modules such as Agent, Task, and Order, and explore integration scenarios between AI Agents and Web3.
- Own stability across core business flows to ensure high availability and high performance; independently diagnose and resolve complex production issues including performance bottlenecks, data consistency, fund safety, and edge-case business scenarios.
