Software Engineer, AI Search Security with DeepMind

Google

  • Lead engineer for multimodal RAG poisoning mitigations on Search, covering text & video injection vectors across AI Overviews and AI Mode
  • Shipped high-precision, low-latency classifiers that suppress adversarially self-promotional and biased content in AI Mode, improving result integrity & factuality across billions of queries per month
  • Architected self-improving red-teaming systems that autonomously generate, mutate, and score prompt-injection attacks, surfacing novel attack classes into Gemini post-training and Cyber model training
  • Designing RL / continual-learning environments so RAG poisoning defenses adapt as attack strategies shift, in collaboration with DeepMind
