Tesla is suing former engineer Alexander yatskov for allegedly stealing’confidential and tightly guarded’ information related to the company’s supercomputer technology. In a copy of the complaint, Tesla accuses yatskov of downloading the information to his personal devices and refusing to give it back.

Yatskov worked for Tesla as a thermal engineer in January. He aided in the design of Dojo’s cooling systems.

Tesla says engineers signed a non-disclosure agreement that should prevent them from disclosing or storing confidential information about Dojo. The company also says it discovered yatskov sending emails with classified Tesla information from his personal email address to his work email.

Tesla claims yatskov hid classified information on his personal devices. The EV maker then put yatskov on administrative leave starting April 6th, 2022. yatskov responded by allegedly providing Tesla with a’dummy’ laptop.
