Software Development Engineer, Amazon Ads Geographic Targeting

Application deadline: Sep 28 2026

Amazon Ads is building the systems that determine where billions of ad impressions land geographically every day and we need a Software Development Engineer to lead that work. Youll own the architecture that scores location signals in real time turns those scores into bid-time features and connects advertiser targeting to the physical world.

The Geo Targeting team sits at the intersection of ad tech large-scale data infrastructure and applied ML. Our systems process billions of bid requests daily fusing multiple location signal sources to determine where an impression is coming from and how confident we are in that answer. The challenge is that location signals are noisy often conflicting and vary in reliability by country device type and signal source. Youll design the systems that make sense of that noise at bid-time latency at global scale under evolving privacy constraints. This is a hands-on engineering role where youll write production code lead design reviews mentor engineers and own systems that directly affect how hundreds of thousands of advertisers reach customers.

Key job responsibilities
- Build and extend location signal processing systems that ingest score and resolve geo data sources at bid-time latency
- Implement and maintain data pipelines that connect address and device signals to impression-level location inference
- Own component-level integration between location intelligence systems and the bid optimization stack
- Contribute to solutions for international coverage gaps working with senior engineers to identify and address unreliable location inference methods
- Drive operational excellence within your scope of geo infrastructure ownership including latency monitoring accuracy measurement and cost efficiency
- Participate in design reviews and mentor junior engineers on your team

A day in the life
Your days are anchored in code but the problems change. One morning youre building a pipeline that processes location signals across billions of daily requests. That afternoon youre digging into data to figure out why accuracy drops for a specific carrier in Germany. The next day youre in a design review with scientists and bidding engineers working through how to turn a noisy signal into something the bidder can act on in microseconds. You own what you build from design through production operations. You also mentor engineers on your team and interview candidates. The problems are hard the scale is massive and the impact is direct.
