Senior Machine Learning Scientist

Adyen is looking for a Senior Machine Learning Scientist to join our team in Amsterdam, a person sitting at the cornerstone of algorithms, mathematics, and engineering, who can solve problems by designing and implementing production-ready machine learning solutions. You will be responsible for building, developing and deploying algorithms that power data products at Adyen. 

In this role, you will: 

• Research, design, implement, train, deploy and monitor machine learning algorithms, either for batch prediction or real-time. Examples are: 
  • Anti-Money Laundering (AML) systems. 
  • Real-time anomaly detection based on time-series modeling.
  • On-line learning algorithms to pick the best optimization decision in a changing environment.
  • Clustering algorithms to group customers/shoppers.
  • Supervised and semi-supervised learning methods for inference on risk patterns.
  • Graph analysis and representation learning for behavior prediction and monitoring.
• Develop orchestrated pipelines for analytical purposes and machine learning training.
• Contribute to ongoing automation efforts for our experiments, training runs, validation runs and monitoring before, during and after deployment. Furthermore, collaborate with MLOps to improve our machine learning tooling.
• Create and iterate on state of the art machine learning algorithms with both merchant and product audiences.
• Stay up-to-date with the latest research and developments in the machine learning field, and apply this where applicable.

Who You Are:

• You have 8+ years of experience as a machine learning or data scientist.
• You have experience with the full machine learning model lifecycle in production flows.
• You have experience leveraging a big data framework to create the pipelines needed to feed the models with appropriate data.
• You have a good understanding of software engineering practices as well as data engineering and MLOps principles.
• You have knowledge of data science and statistics and machine learning techniques. These include a strong grounding in statistical inference, machine learning for prediction, and causal inference. Familiarity with graph-based techniques and Bayesian approaches is considered a plus.
• You have strong familiarity with the standard data science toolkit, such as (py)spark, (Trino) SQL, Scikit-Learn, PyTorch, XGBoost/LightGBM, Pandas, MLFlow or similar MLOps frameworks, and Airflow.
• You have an experimental mindset with a launch fast and iterate mentality. Extensive experience with designing and running experiments is essential.
• You are proactively taking the lead in projects, from ideation to deployment. You have experience working with a wide range of stakeholders and can clearly communicate complex outcomes over a wide range of audiences.
