Join us at SB Energy, the renewable energy company of SoftBank Group. Our vision is to become the global leader of the energy transition to clean sources of power.

SB Energy develops, constructs, and owns and operates some of the largest and most technically advanced renewable projects across the United States, with Headquarters in San Francisco, CA. The company was formed in 2015 as a subsidiary of Japanese multinational conglomerate SoftBank Group Corp. SB Energy entered the United States energy market in 2019 through the acquisition of 5 contracted utility-scale solar projects, bringing its contracted development pipeline to 1.7 gigawatts (GW) of renewable energy projects in the US. In 2020, SB Energy started construction on these 5 new solar projects across California and Texas, created 10,000+ direct and indirect jobs, and will power 330,000+ homes when all 5 projects are complete.

SB Energy also collaborates across the SoftBank ecosystem of companies to innovate solutions for the power industry, including making investments in next-generation energy technologies such as iron-based battery company ESS, Inc. Come join us in accelerating the energy transition to cleaner, more sustainable sources of power!
