Responsibilities

• Contribute to and execute the actor safety strategy in collaboration with the PM and Eng leads by blending abuse prevention frameworks with targeted, tactical protections. Analyze complex abuse patterns and system precision/recall metrics to drive continuous improvements across our AI models (mScore, potential damage, identity change), detection systems, and operational workflows in close collaboration with partner Trust and Safety teams.
• Design, train, deploy, and iterate on ML models including Gemini LLMs, GNNs, and NLP architectures to detect spam, fraudulent actors, and abusive behaviour across shopping products. Build data pipelines for training data curation, establishing active learning workflows, synthetic datasets, and robust frameworks (LLM-as-a-judge) for model evaluation, monitoring, and performance tracking.
• Design and build high-throughput, resilient back-end services with production hygiene. Build our intelligence platform, managing models and seamlessly integrating with the actor lifecycle.
