Software Development Engineer II (SDE II) for Amazon India Ads, focusing on building scalable, low-latency AI/ML solutions for digital advertising. The role involves designing and implementing ML infrastructure for recommendations, ads ranking, personalization, and search, integrating generative AI and LLMs. Responsibilities include working with modern AI/ML technologies, driving technology choices, contributing to technical direction, coding and supporting distributed systems, implementing AI-powered products, and owning product operations with a focus on responsible AI.

What you'd actually do

  1. You will design and build large-scale ML infrastructure for online recommendation, ads ranking, personalization, and search — including integrating generative AI and LLM-based approaches to improve ad relevance and customer experience.
  2. You will work with modern AI/ML and Big Data technologies such as AWS (SageMaker, Bedrock, EMR), Spark, PyTorch/TensorFlow, vector databases, LLM serving frameworks, and real-time inference pipelines.
  3. You will drive appropriate technology choices for the business — evaluating when to apply traditional ML vs. foundation models, leading continuous innovation, and shaping the future of India Advertising.
  4. You will follow and contribute to the technical direction of our offerings and solutions, working across the India Advertising organization with many different technologies including LLM orchestration, RAG pipelines, and agentic systems.
  5. You will code, troubleshoot, and support high-volume, low-latency distributed systems — including ML model serving and real-time feature stores. What you create is also what you own.
