Battery Software Engineer at King Energy

The Company:

King Energy is a leader in rooftop solar and battery storage, serving commercial and industrial properties across the United States.

Powered by King Energy’s OneBill software platform and backed by significant venture capital and project financing investment, we deploy solar on commercial rooftops and provide the energy generated to both local tenants and members of the broader community.

Our goal is to generate financial value for commercial property owners, their tenants, and the broader community by engaging in rooftop leases that increase a property’s net operating income and by saving tenants and local residents money on their energy bills.

King Energy solar programs are deployed at no cost to property owners or their tenants, generating financial, social and environmental benefits to the property and to the community.
