Security Products group is responsible for the protection of customer and corporate data. It is connected to all parts of Amazon’s business and its massive worldwide service-oriented architecture. They are starting the work on a new mission-critical system that will preserve and improve the trusted experience that Amazon provides to its customers. This is a greenfield initiative with plenty of opportunity for innovation in the security space through new machine learning techniques.

They are seeking a talented, self-directed Applied Scientist to work on cutting-edge security technologies. You’ll design and run experiments, research new algorithms, and find new ways of protecting Amazon’s customer trust. Besides theoretical analysis and innovation, you will work closely with talented engineers to put your algorithms and models into practice. You should thrive in ambiguous environments that require finding solutions to problems that have not been solved before. You enjoy and succeed in fast-paced environments where learning new concepts quickly is a must. You leverage your exceptional technical expertise, a sound understanding of the fundamentals of Computer Science, and practical experience in building large-scale distributed systems. Your strong communication skills enable you to work effectively with both business and technical partners.
