I am currently working at ByteDance as head of the applied machine learning (AML) research team. Previously, I worked as a research scientist at Google. Even earlier, I received my PhD from Computer Science Department, Princeton University. Our team works on fundamental machine learning research and its applications for many of our products, such as TikTok and Douyin, among others. We are actively hiring research engineers, scientists and interns. Please apply here: research scientist and research engineer. If you are a new graduate, you can apply here. Feel free to use my referral code: My referral code: UN7TKMA. Contact: chong.wang@[companyname].com
