Amazon's Sponsored Products advertising business is one of the fastest growing areas in the company. Have you ever wondered what happens behind that “Sponsored” label you see in search results on Amazon? Hint: it involves a lot of interesting tech delivered by a great team.
The Sponsored Products team optimizes the systems and ad placements to match demand with supply using a combination of data-driven product innovation, machine learning, big data analytics, and low latency/high-volume engineering. By the time organic search results are ready, we've processed all of the potential ads and determined which ones are going to be shown. We do that billions of times per day, resulting in millions of engagements with products that might otherwise not have been seen by shoppers.
The business and technical challenges are significant. Fortunately, we have a broad mandate to experiment and innovate, and a seemingly endless range of new opportunities to build a big, sustainable business that helps Amazon continuously innovate on behalf of all customers.We're looking for customer-obsessed, innovative, professional engineers who can help us take our products to the next level of functionality, quality and performance. We embrace leaders with a startup mentality — those who seek a disruptive yet clear mission and purpose, have an unambiguous owner's mindset, and are relentlessly obsessed with delivering amazing products. As a Software Engineer on our team, you will be responsible for delivering large-scale, operationally robust software running sophisticated machine learning models that allow us to perform optimizations on Sponsored Products advertising campaigns. You'll own significant products and features from design through launch, and will work with product managers, scientists, UX designers, and other engineers to make your efforts successful. If this sounds like your sort of challenge, read on.
