About the Role

We are seeking a Staff Data Scientist to join our AI-first team at Holidu, based in Munich, Germany. This is a brand-new role where you will bring deep expertise and hands-on excellence to our hardest, most ambiguous ML problems. You'll set technical direction, raise the bar, and multiply the impact of everyone around you, while staying hands-on in the code and the models.

This role is based in Munich with two office days/week.

Responsibilities

As a Staff Data Scientist, you will:

• Own flagship ML initiatives end-to-end - architecting, building, and shipping the models our most important applications run on, and proving their impact.
• Set technical direction and standards for the Data Science team: modelling approaches, experimentation rigor, MLOps, and code quality.
• Act as a force multiplier - mentor data scientists, review designs and models, and level up the whole team's craft.
• Partner with leadership to shape the company-wide ML roadmap, spotting where data science can unlock the most value next.
• Champion AI across the team - continuously integrating it into our data science workflows and finding ways to make our processes and systems smarter and more efficient.
• Bring clarity to complexity - communicate trade-offs and recommendations to both deeply technical and non-technical audiences.

Requirements

• Substantial experience as a Data Scientist / ML practitioner (typically 5+ years), with a clear track record of shipping high-impact models to production end-to-end.
• A quantitative degree in Machine Learning, Computer Science, Mathematics, Physics, or a related field.
• Deep expertise across statistics, predictive modelling, and machine learning, with the judgment to pick the right approach - and the engineering skill to ship robust, production-quality systems, with or without AI writing the first draft.
• Deep, hands-on experience with tree-based and gradient-boosting models (XGBoost, LightGBM, CatBoost) on large-scale tabular data.
• A history of technical leadership - you set direction, mentor others, and leave every team you touch stronger.
• A proactive, ownership-driven mindset - you naturally take the hardest problem in the room and see it through.
• Clear communication - you make complex ideas simple for technical and non-technical audiences alike.
• Genuine enthusiasm for using AI in your daily work - you experiment, adopt what works, and set the example for others.
