I am a CA resident and will be starting a new Job for a company based out of MA, as a remote worker. The company is registered in Delaware. Will I be double taxed?

Since there are 3 states involved, I am not quite sure how the state taxes are going to work. 

Delaware = where the company is registered

Massachusetts = where they are headquartered 

California = where I will be working. 

Thanks for the help of the community!
