Applied Scientist I, Ads Trust Science, Bangalore Every ad that reaches a customer through Amazon DSP has passed through a system you'll help build. The Ads Trust Science team protects one of the world's largest advertising ecosystems , We moderate millions of ad requests a day across 1P and 3P publisher platforms globally across different languages. And we're scaling by an order of magnitude from here. This isn't a research team working in isolation, it's a science team whose models ship into production and directly decide what customers should not see. You'll build ML models that understand ads the way a human reviewer would: reading text, parsing images, catching intent, across languages and cultures. You'll work at the frontier of multimodal content understanding, combining vision and language models to solve problems that don't have off-the-shelf solutions, because the scale and stakes are unlike almost anywhere else. What you'll actually do: - Design and train multimodal (vision + language) ML models that flag or clear ads at massive scale - Push these models beyond English. You will build systems that generalize across languages, scripts, and cultural context - Take models from notebook to production: write the code, build the pipelines, and own the systems that moderate millions of ads a day - Partner closely with engineers and fellow scientists to turn a research idea into something that runs reliably at Amazon scale - See your work matter immediately: a model you ship this quarter is protecting customers next quarter Why this role: - Rare combination: real research problems (open-vocabulary understanding, low-resource languages, cross-modal reasoning) with real production impact and real scale - You won't be the only scientist working on a narrow slice rather you'll have end-to-end ownership from problem formulation to deployment - Trust and Safety at Amazon's size is a genuinely hard, underexplored ML problem. Most of what you'll build doesn't exist in a textbook yet
