Build the Operating System of the Energy TransitionMost internships have you sitting in meetings, fixing small bugs, and watching others build.
This one doesn't.
At Reonic, you'll work on software used by thousands of renewable energy companies across Europe.
You'll ship real features, solve real problems, and see your code in production within days.
We're building the AI-native operating system for renewable installers.
And we're looking for ambitious builders who want to learn fast, take ownership, and make an impact from day one.
This is a full-time, on-site internship based in Berlin.
What makes this internship differentYour work directly impacts how renewable energy gets deployedYou'll ship production code used by real customersYou'll work closely with experienced engineers, product managers, and foundersYou'll own projects instead of shadowing othersYou'll see the full lifecycle: idea → implementation → customer feedbackNo busy work.
No "intern projects" disconnected from reality.
Just building, learning, and shipping.
What you'll buildDevelop product features across our React, TypeScript, and Node.
