Amit Singhal

In 2000, he was recruited by friend Krishna Bharat to join Google. Singhal ran Google's core search quality department where he and his team were responsible for the Google search algorithms. According to The New York Times, Singhal was the "master" of Google's ranking algorithm – the formulas that decide which Web pages best answer each user's question. As a reward for his rewrite of the search engine in 2001, Singhal was named a "Google Fellow". Singhal served as the head of Google's core search ranking team until his retirement announced on 26 February 2016.

In 2017, he joined Uber as SVP of engineering, reporting to CEO Travis Kalanick, and with his fellow Google alum Kevin Thompson operating as SVP of marketplace engineering.

He left Google on 26 February 2016, following sexual-harassment allegations.

He later joined Uber as Senior Vice President of software engineering in 2017 but was asked to resign for failing to disclose the reason for his resignation from Google. It was later revealed that Google paid him $35 million as his exit package.
