DESCRIPTION
Identity Services owns the systems that enable authenticating and identifying every Amazon customer in the world. Every aspect of the Amazon global business depends on our systems to know who the customer is, and if our systems are not up and running, the company stops. We balance keeping our systems fast, scalable and performant (no exceptions!) with rapidly delivering great features for Amazon customers and our developer partners. In short, we get to own and innovate on a critical customer experience while also supporting nearly every other business at the company; the best of both worlds!
The Authentication Workflows team within Identity Services provides the authentication solution on the web for Amazon businesses and subsidiaries. We are looking for software engineers who thrive on complex problems and relish the challenge of operating a complex and mission critical system under extreme loads. Our systems manage hundreds of millions of customer records, and respond to millions of transactions per minute.
