Working Student Linguistics & LLM Monitoring (m/f/d) – Performance Marketing

Deutschland - München
Part-time
Intern / Student

Your tasks

Location: Munich · Hours: 15-20 hrs/week · Start: immediately

What this role is about
ChatGPT, Gemini & Co. answer more and more questions about buying used cars – and mention our brand, category and other services along the way. We are building systematic monitoring of how LLMs portray our brand across our markets (Germany, Spain, Italy, Poland, and beyond) and use it to shape our communications and content strategy. You are the person who builds this data foundation.
To be honest: part of the work is manual and repetitive – tracking prompts, documenting answers, categorizing them. In return, you work in a field that is only just emerging (Generative Engine Optimization, GEO), with direct impact on strategy. Once the foundation is in place, we will improve and automate together – your systematic groundwork is the basis for that.
 
Your tasks 
  • Regular tracking of CARFAX-related prompts and LLM answers per market (using Sistrix, among other tools), on a biweekly cycle
  • Research and documentation of relevant prompts along the used-car buying journey
  • Building a semantic map of CARFAX mentions per language: how, in what context, and with what connotation are we mentioned?
  • Monitoring our competitors' LLM visibility
  • Structured documentation of relevant third-party content and sources (URLs, screenshots, dates) as an auditable evidence base
  • Keyword research in collaboration with our Content Manager
  • Supporting the communications strategy to correct inaccurate LLM portrayals

Your profile

  • Ongoing studies in linguistics, computational linguistics, translation studies, or a comparable field
  • Very good German and English; good command of another of our market languages (Spanish, Italian, or Polish) is a strong plus
  • An analytical, semantically precise way of working – you spot nuances of meaning and can categorize them systematically
  • Persistence and diligence with recurring tasks; clean documentation (e.g., in Excel or Confluence)
  • Interest in SEO, LLMs, and search behavior; experience with tools (Sistrix, Ahrefs, or similar) is a plus, not a must

Why us?


  • Insight into an emerging field (GEO/LLM optimization) with growing relevance in marketing
  • Direct collaboration with the Team Lead Performance Marketing and Content Management, short decision paths
  • The opportunity to help evolve the monitoring from manual to automated
  • Work with a purpose and help creating a fair used car market for everyone
  • A very pleasant atmosphere in an international team (27 nationalities) - we work together, we win together, no jerks allowed!
  • We stand for diversity and inclusion in all its dimensions, we see it as a strength for our teams
  • Great team events like our famous annual Sales Workshop, Hike Day and Christmas Party
