Tech Lead-Machine Learning Engineer (Agent & Multi-Agent Systems) - AIGC Risk Intelligence

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 reasoning

We are seeking an experienced technical leader to define and implement this architecture.

Responsibilities ----------------

• Architect and Implement Agent Systems Design structured agent workflows (e.g., Evaluate Validate Reflect Summarize) Implement ReAct-style tool allocation and reasoning frameworks Develop short-term and long-term memory architectures Ensure robustness under adversarial and evolving conditions

• Lead Multi-Agent Architecture Development Design orchestration layers for coordinating vertical domain agents Build modular Skill systems for extensibility and reuse Define execution graph standards and planning abstractions Establish traceability mechanisms for debugging and auditability

• Develop Open Risk Detection Capabilities Architect systems capable of identifying previously unseen risk patterns Implement execution trace-driven optimization loops Translate feedback signals (FP/FN, reviewer overrides, drift signals) into system improvements Enable proactive rather than purely reactive detection systems

• Establish Engineering Standards for Agent Systems Define traceability, observability, and guardrail requirements Evaluate and integrate multi-agent frameworks where appropriate Ensure production-readiness, scalability, and reliability

• Provide Technical Leadership Own the technical roadmap for Agent and multi-agent systems Partner cross-functionally with Risk, Safety, Infra, and ML teams Mentor engineers and drive architectural rigor

Minimum Qualifications --------------------

• 5+ years of experience in software engineering or applied AI systems
• Deep understanding of LLM-based agent architectures (ReAct-style reasoning/Tool calling systems/Workflow orchestration/Memory design patterns)
• Experience designing distributed or modular AI systems
• Strong backend engineering skills (Python or equivalent)
• Experience operating systems in adversarial or high-stakes environments

Preferred Qualifications ----------------------

• Experience in trust & safety, risk detection, or adversarial ML
• Familiarity with multi-agent orchestration frameworks
• Experience building systems with execution trace logging and observability
• Background in RL-style policy optimization or iterative system refinement
• Demonstrated experience leading high-impact technical initiatives
