For the third time in a year, electric car maker Tesla will have to find another general counsel.

Jonathan Chang, who was appointed Tesla’s general counsel in February 2019, has already moved on from the role after nine years with the company. On Dec. 12, SambaNova Systems, a startup in the artificial intelligence space, announced it hired Chang as general counsel.

At Tesla, Chang had assumed the general counsel role from Dane Butswinkas, who left the job after just two months with the company. Prior to Butswinkas (who represented Musk in his legal battle with the Securities and Exchange Commission), the general counsel role was held by Todd Maron, who was Elon Musk’s divorce lawyer before joining Tesla in-house in 2013.

Chang joins the list of dozens of other Tesla executives who have left in the last three years, some who held their roles for just a few weeks.
