Senior Machine Learning Engineer (m/x/d)

THE ROLE We are looking for a Senior Machine Learning Engineer to design, own, and scale predictive systems that power VIS.X - our programmatic advertising platform. You will take end-to-end responsibility for high-impact ML initiatives (e.g., pricing optimization, bid prediction, performance forecasting, delivery optimization) and translate complex business problems into robust, production-grade machine learning systems. This is a senior individual contributor role with leadership potential. You will help shape our ML architecture, standards, and long-term AI strategy, with the opportunity to grow into a team lead role as we expand our data science capabilities. What You’ll Do Take ownership of machine learning problems from concept to production Design, build, and deploy predictive models (e.g. pricing, bidding, optimization, forecasting) Develop scalable feature engineering and data pipelines for large-scale datasets Define experimentation frameworks (A/B testing, offline validation, model comparison) Ensure production-grade MLOps: monitoring, retraining, drift detection, reliability Collaborate closely with DevOps, Product, Engineering teams to align ML with business impact Quantify model impact on revenue, margin, and performance KPIs Contribute to building our long-term ML architecture and best practices YOUR PROFILE 5+ years of experience in machine learning / applied ML roles with production ownership Proven track record of deploying and maintaining ML systems in real-world environments Strong Python skills (e.g., pandas, scikit-learn, PyTorch/TensorFlow) Solid knowledge of statistics, experimentation design, and model evaluation Experience working with large-scale datasets and performance-critical systems Understanding of MLOps principles (model lifecycle, monitoring, CI/CD integration, retraining pipelines) Strong problem ownership mindset - ability to independently structure ambiguous challenges Ability to translate business trade-offs into modeling decisions Experience in AdTech, marketplaces, or auction-based systems is a plus Experience working in high-scale, real-time systems is a plus Find more English Speaking Jobs in Germany on Arbeitnow
