A little over a year ago, Marco Argenti, a top engineering executive at Amazon Web Services, left the cloud computing arm of the internet retail giant to join Goldman Sachs as co–chief information officer. He brought with him some of the quirky practices he learned at Amazon—and, over time, more than a half-dozen Amazon colleagues followed him to Goldman, The Information has learned.

The former AWS employees who jumped ship over the past year to Goldman include Vladimir Zhukov, who was director of engineering and general manager of Amazon SageMaker, a key AWS service that helps engineers work with machine-learning models, and Rahul Sharma, who was general manager of deep-learning frameworks at AWS, according to people familiar with matter and the employees’ LinkedIn profiles. Both are now managing directors at Goldman, with Zhukov serving as global head of machine learning and data science and Sharma serving as head of identity and access management. A Goldman spokesperson confirmed the changes.
