Principal Software Development Engineer

Req ID:  124023

Do you want to change the world? We do, too.
Solar penetration is less than 1%, but just one hour of sunlight, if harnessed, could power the entire world for a year. We have the opportunity to change the way energy is produced, distributed and consumed, and we’re looking for talented, committed people to help us drive our growth and achieve our goals.
SunPower is a solar energy solutions company with a rich heritage of pioneering the best solar technologies in the world.

As a Principal Software Development Engineer at SunPower, you will build software and services that increase the amount of solar power produced on our planet every single day. SunPower’s mission is to change the way the world is powered.  Solar energy is one of the fastest-growing industries in the US. Not only is going solar beneficial for the planet; for most Americans it also saves money vs. buying power from utilities.  Studies show that the #1 barrier to solar adoption is concern over how to pay for initial installation. The mission of the Financial Products team is to remove that barrier by making it cheap and easy for customers to go solar. This is a green field opportunity allowing for impact at scale almost immediately.

An ideal candidate will approach their job with empathy, seeking to understand existing systems and practices, and building relationships with teams and team members along the way.
