Applied Scientist, Alexa Ads

Amazon Amazon · Big Tech · IN, KA, Bengaluru · Applied Science

Applied Scientist role focused on building Generative AI models for conversational ads and personalization within the Alexa ecosystem. Responsibilities include designing, developing, and evaluating ML models for NLP, recommendation systems, and personalization, building ML pipelines, running A/B experiments, and collaborating on production deployment.

What you'd actually do

  1. Design, develop, and evaluate innovative machine learning and deep learning models for natural language processing (NLP), recommendation systems, and personalization.
  2. Conduct hands-on data analysis and build scalable ML pipelines.
  3. Design and run A/B experiments to measure the impact of new models on customer experience and ad performance.
  4. Collaborate with software development engineers to deploy models into high-scale, real-time production environments.

Skills

Required

  • Java, C++, Python or related language
  • SQL and an RDBMS (e.g., Oracle) or Data Warehouse
  • 1+ years of building models for business application experience
  • Machine Learning and Large Language Model fundamentals, including architecture, training/inference lifecycles, and optimization of model execution, or experience in machine learning, data mining, information retrieval, statistics or natural language processing

Nice to have

  • publications at top-tier peer-reviewed conferences or journals
  • advertising technologies (i.e., ad server, DSP)
  • programmatic advertising technologies (DSP, RTB, bid shading, machine learning optimization, ad verification, ad tracking, ad attribution, etc.)
