Prior to Tesla, Julia spent 8 years with SunPower working in project management and engineering where she supported over 2.5GW of solar projects. Some of her notable projects included Solar Star 1 and 2, a 579MW project sold to BHE Renewables for $2.5B in 2012. She was responsible for all technical aspects of development including permitting, engineering, interconnection, procurement and construction. Julia spent the early years of her career as a structural engineer designing buildings from town homes to stadiums and concert halls.
