- Experimentation & Measurement: Design and run A/B tests and causal measurement to prove the real impact of AI-driven features.
- Data & ML Pipelines: Arbeiten Sie mit groß angelegten Transaktions- und Verhaltensdaten, stellen Sie die Datenqualität und Instrumentierung sicher und bringen Sie Modelle zuverlässig in die Produktion.

Our expectations of you
Qualifications
- Convince us with your skill set and mindset.
- Data Science Foundations: Solid grasp of statistics, machine learning and experiment design (clustering, prediction, uplift, significance) - applied in practice, not just in theory.
- Engineering Skills: Confident with Python (e.g. Pandas, common ML frameworks) and able to bring models into production in a clean, maintainable way.
- Experiment & Causal Thinking: You don't just want to build models - you want to prove they work, with clean measurement and honest attribution.
- Proactive Working Style: A structured, solution-oriented and self-directed approach to new, open-ended problems.
- You are a professional translator for a job portal, specialized in HR and Tech content. IMPORTANT RULES: - Maintain the original formatting and structure of the source text. - Correctly translate technical terms (e.g., "Frontend", "Backend", "DevOps", "Scrum Master"). - Use industry-standard terminology from HR and Tech. - Preserve the tone (formal/informal, Du/Sie) of the original text. - Translate only the text; do not add additional explanations or comments. - Keep the list structure exactly as in the original for bullet points. - Technical terms with international usage may remain untranslated. - Always ensure correct grammar and a natural linguistic flow. Translate the following text precisely into English: Language: Professional English skills; German is a welcome plus.
- Location: You are ready to join our team on-site in Leonding (Linz) or Vienna.
Experience
- What matters more than a specific number of years is how you think and what you have already built - whether you are an early-career talent with strong projects or an experienced practitioner.
- LLM & GenAI Experience: Practical experience with modern language models - prompting, RAG/grounding, tool use, and above all the systematic evaluation of AI outputs.
- AI-First Approach: You use AI tools daily, have built prototypes yourself, and hold a well-founded view on how AI products will evolve over the coming years.
