Working Student - Marketing

What we are building
At ecoplanet, we're building the operating system for the energy transition. Our AI-powered platform turns energy management from a cost center into a competitive advantage for European manufacturers — saving energy costs and unlocking operational efficiency. Backed by EQT Ventures, HV Capital and more and built by a team full of top-tier talent. We're scaling our GTM engine — and we need someone to make sure the systems behind it actually work.
Why This Role Matters
This is not a traditional marketing role. You're the systems brain behind our marketing function leveraging AI to build a highly efficient marketing setup directly with one of our founders. You'll own the entire marketing stack from online, over events to PR and build the infrastructure to track performance of different channels.

You'll thrive in this role if...
You enjoy figuring things out independently
You like building systems instead of doing repetitive manual work
You see AI as a force multiplier
You want to take ownership and have an outsized impact early in your career
How You’ll Grow
What You Get
Competitive compensation: attractive salary
Flexibility: hybrid from our Munich office
Real ownership: you'll shape how marketing operates, not just execute tickets and work directly with the founders
A solid foundation: the tech stack is already in place (HubSpot, Webflow, N8N) — you build on it, not from scratch
