Software Engineering Intern (AI x Greentech) (m/f/d)

• 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 that help installers sell and deliver renewable energy projects faster
• Contribute to backend services, APIs, and internal tooling
• Debug, improve, and optimize production systems
• Collaborate closely with product and design to bring ideas to life

And if you're eager to go deeper:

• Work with databases and PostgreSQL
• Learn about system architecture and scalability
• Explore AI integrations and automation workflows
• Take ownership of larger features end-to-end

This is not a typical internship.

It's a playground for builders.

You'll thrive here if you...

• Love building things and seeing them used by real people
• Are curious and learn quickly
• Prefer ownership over detailed instructions
• Enjoy solving problems, not just writing code
• Care about creating great user experiences
• Want to work with ambitious people who move fast
• Are studying Computer Science, Software Engineering, or a related field

Previous startup experience is a plus, but not required.

What matters most is your ability to learn, execute, and take ownership.
