Embedded Systems Jobs

Our mission at Enphase Energy is to advance a sustainable future for all.

Today, our intelligent microinverters, which turn sunlight into an affordable, safe, reliable, and scalable source of energy, work with virtually every solar panel made, and when paired with our award-winning smart battery technology, we engineer one of the industry's best-performing clean energy systems. To date, we have installed more than 36 million microinverters on more than 1.5 million homes across 130 countries.

Like our customers, our innovative teams are also worldwide, making Enphase Energy a truly global company. We are one of the fastest growing and most dynamic energy companies in the world. Nimble and acutely focused on developing ground-breaking solar energy management technology, each of our teams have a shared goal of creating a carbon-free future.

At Enphase we are also committed to diversity and inclusion. Developing cutting edge technology requires a workforce as diverse as the populations we wish to serve. We are a values-driven company that puts people and their power at the centre of our shared energy future.
