Jerome Guillen, Tesla Inc's chief of heavy transportation, has departed the firm, the electric-car maker announced on Monday, only three months after taking up the position.
Guillen, who has been with Tesla for almost a decade, was designated president of the Tesla Heavy Trucking segment in March, with the responsibility of leading the company's entry into the heavy truck industry.
Tesla has yet to begin delivering its battery-powered Semi electric commercial vehicle, citing supply difficulties as a reason for the delay.
