Applied Scientist II, Alexa Ads
Key job responsibilities
- Design, develop, and evaluate innovative machine learning and deep learning models for natural language processing (NLP), recommendation systems, and personalization.
- Conduct hands-on data analysis and build scalable ML pipelines.
- Design and run A/B experiments to measure the impact of new models on customer experience and ad performance.
- Collaborate with software development engineers to deploy models into high-scale, real-time production environments.
About the team
We are building a new science team in Bangalore to solve some of the most impactful problems in computational advertising. This isn't about tweaking existing models as we are rethinking how ads are ranked, priced, and personalized across voice-first and screen-first surfaces. These are problems that don't have textbook solutions. Key points to note about the team:
🧪 Greenfield team - you are not joining a mature org with rigid processes. You will shape the science roadmap, pick the problems, and define the culture from day one.
📈 Direct business impact — your models directly drive revenue. No yearly cycles to see if your work matters.
🌏 Global scope, local autonomy — collaborate with scientists and engineers across Seattle, Sunnyvale, and Bangalore, but own your problem space end-to-end.
🎓 Ship AND Publish: We encourage top-tier publications (NeurIPS, ACL, EMNLP, KDD, ICML, WWW) while ensuring your research hits production.
