Applied Scientist I, Ads Trust Science

Description

Applied Scientist I, Ads Trust Science, Bangalore

Every ad that reaches a customer through Amazon DSP has passed through a system youll help build. The Ads Trust Science team protects one of the worlds largest advertising ecosystems , We moderate millions of ad requests a day across 1P and 3P publisher platforms globally across different languages. And were scaling by an order of magnitude from here.

This isnt a research team working in isolation, its a science team whose models ship into production and directly decide what customers should not see. Youll build ML models that understand ads the way a human reviewer would: reading text, parsing images, catching intent, across languages and cultures. Youll work at the frontier of multimodal content understanding, combining vision and language models to solve problems that dont have off-the-shelf solutions, because the scale and stakes are unlike almost anywhere else.

What Youll 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

• Rare combination: real research problems (open-vocabulary understanding, low-resource languages, cross-modal reasoning) with real production impact and real scale
• You wont be the only scientist working on a narrow slice rather youll have end-to-end ownership from problem formulation to deployment
• Trust and Safety at Amazons size is a genuinely hard, underexplored ML problem. Most of what youll build doesnt exist in a textbook yet

• Experience building machine learning models or developing algorithms for business application
• Experience in state-of-the-art deep learning models architecture design and deep learning training and optimization and model pruning
• Currently has, or is in the process of obtaining, a Masters degree or equivalent in Engineering, Computer Science, Machine Learning, Operations Research, Statistics, or related fields
• Experience researching about machine learning, deep learning, NLP, computer vision, data science
• Experience programming in Java, C++, Python or related language
• Experience with SQL and an RDBMS (e.g., Oracle) or Data Warehouse

• Experience applying theoretical models in an applied environment
• Have publications at top-tier peer-reviewed conferences or journals
• Masters degree
