Workster is partnering with a global leader in the mobility industry to recruit a Senior Data Scientist – Reinforcement Learning (m/f/d) for their growing Data Science & Engineering team in Munich. This is a high-impact opportunity to shape the future of intelligent pricing systems through advanced probabilistic modeling and state-of-the-art machine learning techniques.
You’ll be joining a company that values rigorous science, scalability, and innovation—where your models will directly influence millions of real-time business decisions across global markets.
Your Role
* Architect and prototype Bayesian regression models (GLM, mixed-effects, Gaussian Process) to support dynamic pricing strategies.
* Implement techniques like SVI, MCMC, and importance sampling to make robust decisions under uncertainty.
* Design and maintain feature engineering pipelines and automated data validation using tools such as Airflow or Dagster.
* Deploy production models via FastAPI, Docker, and Kubernetes, ensuring performance monitoring and anomaly detection are in place.
* Design and evaluate A/B and multivariate tests using causal inference and quasi-experimental methods.
* Collaborate cross-functionally with revenue and product teams to turn abstract ideas into data-driven hypotheses.
* Mentor team members and help elevate internal Bayesian and modeling standards through workshops and publications.
Your Qualifications
* 5+ years of experience in applied statistical modeling, with a strong focus on Bayesian methods.
* Proficiency in probabilistic programming using PyMC, Stan, NumPyro, TFP, or similar tools.
* Hands-on experience with SVI, black-box variational inference, and large-scale MCMC techniques.
* Strong Python programming skills with best practices in testing, type hints, and CI/CD.
* Familiarity with cloud infrastructure (AWS, GCP, or Azure), Docker/Kubernetes, and workflow orchestration tools.
* Excellent communication skills—able to explain statistical concepts and uncertainty to both technical and executive audiences.
The Offer
* A hybrid working model with flexibility and 30 days of paid vacation.
* Opportunities to engage in company-wide learning initiatives and volunteer days.
* Access to on-site fitness and leisure facilities in a modern workspace.
* Mobility support, pension contributions, and generous employee discounts on mobility services.
* A supportive and collaborative team culture with cutting-edge technologies and complex real-world challenges.
