A/B Testing Artificial Intelligence Python (Programming Language) Machine Learning Language Modeling Tensorflow Large Language Models Pandas Machine Learning Operations

Job description

  • We run 1,000+ white-label loyalty programs across Europe, serving 17M+ end consumers in 28 countries.
  • As we move into the next era of loyalty, we are looking for an AI Engineer & Data Scientist (d/f/m) to further build the intelligent core of our platform.
  • In this role you turn transaction and behavioral data into measurable impact.
  • You build the models, pipelines and experiments that move us from a “tool to run loyalty” to a platform that “runs loyalty - and proves it works.”
  • Machine Learning & Data Science: Build and improve ML models that drive personalization and customer insights - e.g. segmentation, churn and behavior prediction, and uplift measurement.
  • Intelligent, Automated Features: Help develop AI-driven, personalized features across our platform, from automated messaging to smart campaign optimization.
  • LLM Integration: Integrate large language models into our product and build robust evaluation and grounding to ensure reliable, high-quality output at scale.
  • Experimentation & Measurement: Design and run A/B tests and causal measurement to prove the real impact of AI-driven features.
  • Data & ML Pipelines: Work with large-scale transaction and behavioral data, ensure data quality and instrumentation, and bring models reliably into production.
  • Prototyping & Impact: Rapidly prototype with modern AI tools, validate ideas directly on real data, and drive data-informed decisions across the team., * 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.

Requirements

  • 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.
  • Language: Professional English skills; German is a welcome plus.
  • Location: You are ready to join our team on-site in Leonding (Linz) or Vienna., * LLM & GenAI Experience: Hands-on 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.

Benefits & conditions

  • Shape our most strategic product initiatives - from Autopilot to our Intelligence Layer to autonomous, hyper-personalized communication.
  • Advance your career in a culture of continuous learning, intensive onboarding and proactive support.
  • Work with a modern stack and choose the hardware that maximizes your productivity.
  • Join a cohesive team with numerous events throughout the year, plus supported fitness memberships and shared sport activities.
  • Benefit from a modern office with parking and excellent public transport connectivity.
  • Shape the future of our platform alongside international talent in a high-growth, value-driven setting.
  • We offer a base salary of € 60,000 gross per year, with a market-competitive overpayment depending on your track record and expertise.
