Job description

Join to apply for the Backend Engineer role at Svea Solar.

Svea Solar is on the verge of transforming how we manage energy with just the click of a button. We’re here to help our customers make the most of their energy usage while also balancing the energy grid with smart, innovative solutions. To bring this vision to life, we’re expanding our engineering team and are on the lookout for our next Backend Engineer.

About The Role & The Team

As a Backend Engineer, you’ll join our Sunbeam Labs, where we’re creating digital services that range from energy optimization to virtual power plants. You’ll work closely with a talented and energetic team of engineers and domain experts, all focused on building cutting‑edge software solutions that make energy optimization a reality for our customers.

In this role, you’ll be involved in every stage of the software development lifecycle, from brainstorming ideas to deployment and ongoing maintenance. Since we’re pioneering services that haven’t existed before, there’s plenty of room for discovery and problem‑solving! You’ll be working with thousands of connected devices that we control in real time, based on measurements taken multiple times per second. Your daily challenges might include figuring out how to distribute work among devices, handling AWS datacenter fail‑overs without a hitch, counting milliseconds and megawatts, and even predicting tomorrow’s sunshine.

If you love tackling challenges, writing code, and having fun while doing it, this could be the perfect fit for you!
