Amit Singhal, Uber's senior vice president of engineering, has left the company after it was revealed that he did not disclose a sexual harassment allegation against him at Google, where he was previously employed, Recode reported on Monday. Singhal left Google last year, following a sexual harassment allegation from an employee. A Google investigation found the allegation to be "credible," according to Recode. Singal disputed the allegations while at Google, but resigned from the Google post shortly thereafter, ending his 15-year career with the company. He reportedly did not inform Uber of the allegations when he applied for his new job, and the allegations did not surface during a background check. Uber CEO Travis Kalanick reportedly asked Singhal to resign Monday morning. Uber is currently undergoing an internal investigation into alleged sexism at the company, after a female former engineer published an essay detailing a culture of harassment and inequality earlier this month. Uber has hired former attorney general Eric Holder to lead the investigation, alongside Uber board member Arianna Huffington, Uber human-resources chief Liane Hornsey, and Uber Associate General Counsel Angela Padilla. Critics have suggested that the team, composed mostly of Uber stakeholders, could be biased in Uber's favor.
