Amazon Ads Brand Safety & Suitability protects advertisers from exposure to unsafe, unsuitable, or policy-violating content across web, mobile app, CTV, and audio advertising inventory. Our mission is to ensure that every ad impression delivered through Amazon's demand-side platform appears adjacent to content that meets advertiser trust expectations while giving brands granular controls to define suitability on their own terms. We operate at the intersection of advertiser trust, publisher quality, and supply integrity.
What Makes This Role Unique
Generative AI has dramatically lowered the cost of producing deceptive, policy-evasive content, and the adversary evolves daily. Your detection systems must reason contextually, adapt rapidly, and generalize beyond previously seen content risk patterns. Static models fail here; you will build living systems that learn and respond in real time. You will do this at internet scale, developing low-latency ML and LLM‑powered systems evaluating content safety, brand suitability, misinformation risk, and emerging content risk vectors across massive real‑time traffic streams, making billions of decisions per day with single‑digit millisecond latency constraints. This role sits at the intersection of frontier AI research and large‑scale production engineering, combining deep science, system‑wide impact, and business‑critical outcomes. The models your team ships directly influence billions of dollars in advertising spend and the trust of the world's largest brands in Amazon DSP.
The Science Problems Are Genuinely Hard
You will tackle challenges including detecting sophisticated AI‑generated and synthetic content, understanding nuanced contextual brand risk, identifying coordinated MFA space before they scale, balancing precision, recall, latency, explainability, and fairness, designing adaptive models resistant to adversarial evolution, and leveraging LLMs for semantic understanding in real‑time, latency‑constrained environments.
Why This Matters
Few roles offer the opportunity to work at the intersection of frontier AI, internet‑scale production systems, adversarial environments, and business‑critical impact—while tackling open‑ended scientific challenges with real‑world societal relevance. As AI reshapes the internet, the systems your team builds will define what trustworthy, high‑quality digital systems look like for the next decade.
