Responsibilities

Our team is building the next generation of AI-native risk intelligence systems to address emerging challenges driven by large-scale AIGC content production.As content creation becomes automated and adversaries adopt systematic experimentation (e.g., large-scale template variation and rapid iteration), traditional rule-based and single-model approaches are no longer sufficient. We are transitioning from monolithic LLM applications to a structured multi-agent architecture that emphasizes:- Tool-augmented reasoning (ReAct-style systems)- Modular skill composition- Execution traceability and observability- Feedback-driven system evolution- Cross-domain risk reasoningWe are looking for talented individuals to join our team. As a graduate, you will get opportunities to pursue bold ideas, tackle complex challenges, and unlock limitless growth.Successful candidates must be able to commit to an onboarding date by the end of the year. Please state your availability and graduation date clearly in your resume.

• Tool-augmented reasoning (ReAct-style systems)
• Modular skill composition
• Execution traceability and observability
• Feedback-driven system evolution
• Cross-domain risk reasoning
