Job summary

Amazon's Talent Assessment team ensures the right people are matched to the right roles, quickly, fairly, and with an amazing experience. To achieve this, we design, implement, and optimize hiring systems experienced by millions of candidates annually. We work in a data-rich, global environment solving complex problems with deep thought, large-sample research, and advanced quantitative methods to deliver practical solutions that make all aspects of hiring more fair, accurate, efficient, and enjoyable.

Key job responsibilities

We're looking for a thoughtful applied scientist interested in working on a multi-disciplinary team to create products with a wide audience of users and high business impact in a high regulation environment. In this role, you will apply your skills in collaboration with cross-functional teams of psychologists, UX researchers, engineers, and product managers, to research, develop, analyze and implement new talent assessment products intended to measure and predict exactly what it requires to be an engaged and successful employee at Amazon.

A day in the life

You will work with a variety of data sources (e.g., structured assessment question responses, unstructured text or audio data, mined data, behavioral data) requiring a breadth of ML knowledge and techniques to deploy scalable algorithms and products. Deployed products must also meet strict fairness and model interpretability standards. You'll be expected to stay informed on the latest machine learning, natural language and artificial intelligence trends.
