Software Engineering Intern (AI x Greentech) (m/f/d)
About this role
Build the Operating System of the Energy Transition
Most 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 different
Your work directly impacts how renewable energy gets deployed
You'll ship production code used by real customers
You'll work closely with experienced engineers, product managers, and founders
You'll own projects instead of shadowing others
You'll see the full lifecycle: idea → implementation → customer feedback
No busy work. No "intern projects" disconnected from reality.
Just building, learning, and shipping.
What you'll build
Develop product features across our React, TypeScript, and Node.js stack
Turn complex business workflows into simple and intuitive user experiences
Work on AI-powered workflows
