Marketing & Content
Marketing & Communications
Munich, Germany
Posted on Jul 31, 2026
We have a strong product, an honest story and seven pilots live, but barely any reach yet. You own the brand voice, the content, the social presence and the campaigns of a young startup for the trades. Not decorative posts, real reach.
What you’ll do
- Define how KAI sounds and set the content rhythm: what we post, in which channel, in what voice.
- Plan and produce content for Instagram, Meta and WhatsApp that actually reaches the trades.
- Set up and test campaigns, from the idea to the measured result.
- Sharpen our story: why KAI, why now, why transparent.
What you bring
- You write well, have a feel for social, and dare to test things.
- You work independently and want to shape a brand from early on.
- You use AI tools (Claude, ChatGPT, Gemini or similar) to produce and iterate content faster.
- German fluent (must), our content is German-facing.
Why KalkulAI
- Radical ownership from day one. No fixed job description, you own outcomes.
- A live product with real pilot customers, not a lab hypothesis.
- You never start from zero: you build on real, existing progress.
- AI-native: Claude, Codex, GPT and Gemini are part of how we work every day.
- You sit side by side with the founding team.
- Honest deal: this is unpaid, but you gain real ownership and startup experience most roles never offer.
- Backed by EXIST, TU Munich and UnternehmerTUM.
How to apply
- 1 Apply with your CV, transcript and a short motivation as one PDF, to leon@kalkulai.de.

- 3 After a yes, we set up the format together: as an unpaid internship, or we handle the TUM Projektstudium registration and exposé at the chair.
