Job Description
We work at the intersection of pricing science advanced statistics and scalable software. Youll build and bring in production state-of-the-art probabilistic models - like hierarchical Bayesian regression SVI or bandit algorithms - that power millions of pricing decisions at SIXT every day. From shaping the analytical question to deploying live models youll own the full lifecycle supported by an innovation-friendly culture and great team. If youre excited by real-world impact rigorous methods and turning cutting-edge ideas into production - even if you dont tick every box - wed love to hear from you!
YOUR ROLE AT SIXT
- You architect and prototype advanced regression models (linear GLM mixed-effects Gaussian Process) with a principled Bayesian approach guiding pricing strategy at scale
- You apply techniques like SVI MCMC and importance sampling to enable robust decision-making under uncertainty even with sparse high-volume or streaming data
- You build and maintain reproducible pipelines for feature engineering label generation and automated data validation using tools like Airflow or Dagster ensuring high code quality and reliability
- You deploy models via FastAPI Docker or Kubeflow and establish real-time monitoring with Bayesian control charts and performance dashboards to catch drift and anomalies early
- You design sophisticated A/B and multivariate tests apply quasi-experimental and causal impact methods and quantify the value of information to balance exploration and exploitation
- You collaborate with product and revenue leaders to translate ambiguous ideas into testable hypotheses while mentoring peers and elevating Bayesian practice through internal publications and workshops
YOUR SKILLS MATTER
- Expertise You bring deep statistical chops with 5 years of applying regression hierarchical models or state-space methods in production
- Computing proficiency You have a well-stocked Bayesian toolbelt - fluent in PyMC Stan NumPyro TFP or similar - and are comfortable writing custom likelihoods and priors.
- Modeling You have proven experience scaling inference using SVI black-box VI or advanced MCMC techniques on large datasets
- Engineering practices You write solid production-grade Python code and are familiar with type hints testing frameworks and CI/CD workflows
- Infrastructure You are hands-on with cloud platforms like AWS GCP or Azure and have experience with containerization (Docker/K8s) and workflow orchestration
- Stakeholder management You communicate uncertainty lift and risk in plain English for executives while engaging deeply with scientists and engineers
