What if you could build the machine learning systems that decide which ads hundreds of millions of shoppers see—across every Amazon surface, worldwide?
The Sponsored Products and Brands - General Shopping Intelligence is looking for a talented Software Engineer with a strong machine learning engineering background to help us push the boundaries of ad relevance at Amazon scale. You'll partner with engineers and scientists to build advanced ML models and infrastructure—from training to inference—including emerging LLM-based systems that connect shoppers with the most relevant ads at exactly the right moment.
We're a highly motivated, collaborative team with a strong entrepreneurial spirit and bias for action. If you thrive in fast-moving environments where your work directly drives business growth and customer experience, this is where you'll do your best work.
Key job responsibilities As a Software Development Engineer in Machine Learning, you will:
Design, build, and operate near-real-time (NRT) data ingestion pipelines using Apache Flink, Kinesis, and DynamoDB that process shopper behavioral signals at scale (100K+ TPS, sub-second latency)
Develop and maintain ML feature generation services that transform raw customer interactions into ML-ready signals consumed by prediction models across Amazon Ads
Enhance the scalability, automation, and efficiency of large-scale training and real-time inference systems.
Build and improve data quality monitoring frameworks, automated alerting, and self-healing mechanisms to ensure signal reliability at 99.9%+ availability
Collaborate with applied scientists and partner engineering teams to onboard new shopper signals, define feature schemas, and optimize serving latency for real-time ad personalization
Contribute to system design discussions, propose technical solutions for ambiguous problems, and drive implementation end-to-end with guidance from senior engineers
A day in the life
Highly analytical — You solve problems backed by verifiable data, driving processes, tools, and statistical methods that support rational decision-making
Humbitious — Ambitious yet humble; you use introspection and feedback to continuously raise the bar
