Are you passionate about building systems that power advertising at internet scale? The Supply Forecasting team within Amazon Ads is seeking a Software Development Engineer to help shape the future of programmatic advertising for our publisher partners.

Our team builds the critical infrastructure that enables publishers across Prime Video, Twitch, Freevee, and other Amazon properties to forecast inventory, book guaranteed advertising deals, and maximize monetization. Every day, our systems process billions of ad events and serve real-time availability queries that directly impact deal creation and revenue optimization.

Key job responsibilities
- Design and implement scalable, highly available services and APIs that enable customers to book programmatic guaranteed deals and simulate inventory contention
- Build fault-tolerant distributed systems capable of processing internet-scale data volumes with sub-hour latency requirements
- Own the full software development lifecycle—from architecture and design through deployment, monitoring, and operational support
- Drive technical excellence by establishing best practices, conducting thorough code reviews, and maintaining high quality standards
- Collaborate across Amazon Advertising teams to integrate solutions and deliver end-to-end customer experiences
- Mentor team members and contribute to a culture of continuous learning and improvement

A day in the life
You will be working with a team of Software Development Engineers on building inventory forecasting and allocation systems that power programmatic guaranteed deals for Amazon's publisher partners.

You will participate in design reviews, contribute to technical discussions, and collaborate with other teams within Supply Tech on integration solutions. You will attend daily standups with the engineering team and work with product managers to understand publisher requirements and ensure the features you're building solve real customer problems.
