Software Development Engineer, Amazon Ads Nova

Amazon Advertising is building a startup team to tackle a greenfield problem: simplifying full-funnel advertising solutions at internet scale for strategic verticals including financial services, automotive, and local businesses. There is no known answer or existing pattern to follow—we are defining the space from the ground up with specialized agentic AI-powered models that will diversify demand and transform how vertical advertisers grow on Amazon. We are seeking a Software Development Engineer to help evolve the tools, services, and frameworks that power this new product area. You will lead innovation in an ambiguous, fast-moving environment where the problems are big, the solutions are yet to be invented, and the impact is immediate.
