Jerome Guillen, a veteran at Tesla and a key executive that was working on the Tesla Semi, a battery electric semi-truck, has left the company, as reported in a U.S. SEC filing on Monday.

Guillen recently was moved to Head of Heavy Duty Trucking in March, a role that carried much less oversight than his previous one. Before the switch, Guillen was in charge of running Tesla’s entire automotive business and had direct oversight on the Tesla Semi project. previously in charge of the Tesla Semi.

A former Daimler executive, Guillen is also responsible for the development of the company’s new generation of Class 8 trucks. He first joined Tesla in 2010, reporting directly to CEO Elon Musk as the Program Director of the Model S, and later as the VP of Vehicle Engineering.

The Tesla Semi is still in development but is unclear if Guillen’s departure means further delays in its release. It was originally slated to go into production in September 2019. This past January, Musk said that all the engineering work on the Semi had been completed, but at the time said it was hindered by a lack of availability in battery cells to start production.

Earlier this year, it was also reported that the company is building a new production line for its semi-model near its Nevada Gigafactory location, with the goal of producing five semi-trucks per week.
