Your role

We are looking for a talented young professional with technical understanding and strong communication skills. As a Customer Success Management intern, you will work closely with our CSMs and support them in making our key accounts (SMEs & enterprises) successful.

You will develop, test and document precise LLM prompts and design AI workflows that work measurably in the customer’s everyday life. You will work closely with our core team, be involved in real projects from day 1 and combine linguistic-analytical thinking with solid technical understanding. No research island – you work hands-on, evidence-based and results-oriented.

This role is your springboard to building in-depth product knowledge and developing into a permanent employee.

Your responsibilities

  • Ensure quality: Analyze responses, perform A/B tests, derive improvements.

  • Fine-tuning with the team: tailoring prompts to specific customer requirements.
  • Support testing: Check classification, analysis or research workflows.
  • Optional: Introduce low/no-code prototypes (e.g. n8n, Microsoft Power Automate) or small scripts.
