Software Development Engineer II — Ads Reporting, Programmatic Reporting Interfaces

Amazon Advertisings Measurement and Data Science (MADS) organization delivers campaign measurement and reporting across the advertising business and serves as the scientific center of excellence for measurement algorithm development. Within MADS the Programmatic Reporting (PREP) team builds the interfaces and engines that turn measurement data into consistent accurate and efficient reporting for advertisers and partners through programmatic interfaces rather than dashboards. Other companies systems talk to ours to measure and grow their Amazon advertising investment.

We operate at scale. Billions of ad impressions clicks and conversion events are processed and summarized every day across petabyte-scale data with millions of transactions per second. Delivering this reliably requires invention ahead of common technologies and event-driven architectures built on AWS.

This SDE II role spans two of our three tier-1 reporting surfaces and the engines behind them:

- Reporting API the pull surface: an asynchronous API for occasional experimental and analytical queries and the back end to the Unified Report Builder.
- Amazon Marketing Stream the push surface for recurring high-volume reporting data.
- The processing engines including the Offline Engine (Iceberg Spark on EMR) that computes the data those surfaces deliver.

You will own projects end to end requirements system design implementation testing and production support on systems built with Spark and EMR alongside AWS services including Lambda S3 SQS Step Functions Kinesis and DynamoDB. The work is high-ownership and collaborative: you will partner with senior and principal engineers on architecture and with product managers and technical account managers to translate customer pain points into features. You will also help deliver Unified Reporting as Amazons single programmatic reporting solution and shift high-volume recurring consumption from repeated API polling toward Amazon Marketing Stream.

Amazon is investing heavily in a world-class advertising business and this team is at the forefront of that growth. We are highly motivated collaborative and direct with a strong bias for action and a broad mandate to experiment. We start with the customer and work backwards in everything we do. If you want to build the next generation of large-scale reporting systems on modern data and AWS technologies we would like to hear from you.
