Mollie is on an exciting journey.

We are looking for an experienced Data Scientist to join our growing team of Data Scientists (DSs) & Machine Learning Engineers (MLEs).

We primarily develop predictive ML models that provide decision intelligence to our colleagues in various departments, such as Product, Operations, and Commerce. We also maintain a cloud-based ML Platform, which we use for both model development and production.

In this role, you will be focused on developing ML models for Operations, to tackle challenges in fraud, transaction monitoring, credit risk, integrity risk, and more. This is a hands-on role, where you will spend most of your time developing in Python together with our team of DSs and MLEs. You will also be interfacing directly with subject matter experts & stakeholders, e.g. to evaluate the feasibility of potential DS use cases or to explain how your model works during a Sprint Review.

This role is based at Mollie’s new Milan Hub. You will be part of a geographically-distributed team (Amsterdam/Lisbon/Milan) that is comfortable collaborating virtually & hybrid.

  • Perform efficient exploratory data analysis (EDA) and present key insights to colleagues & stakeholders
  • Contribute regularly to our bi-weekly DS Community of Practice (knowledge sharing sessions)
  • Adopt best practices and standards for the development of ML models
  • Collaborate closely with MLEs to prepare your code & model for production using our ML Platform
  • Help evaluate the feasibility of new use cases for ML in Operations


What you'll bring
  • 1-3 years experience in data science and machine learning, including the development of models that successfully went to production 
  • You have experience with tabular datasets and applied ML, in particular regression and classification problems using boosted decision tree algorithms
  • You approach complex problems in a structured way, always looking for the simplest, pragmatic solutions
  • You understand the technical and non-technical constraints of a business problem
  • You are detail-oriented but can also quickly shift priorities if required
  • You enjoy working collaboratively in a cross-functional & distributed team environment
  • You have excellent presentation skills and can communicate to a wide variety of audiences
  • You have a strong foundation in statistics
  • You have solid software engineering skills and love coding in Python
  • You know your way around a linux shell and are comfortable with Git for version control
  • You know the scikit-learn API inside and out
  • You are comfortable in an agile Way of Working, with Scrum or similar frameworks


Nice to have
  • Experience with anomaly detection algorithms
  • Experience with (Py)Spark to handle large datasets
  • Experience in the financial services industry (banking or fintech)
  • Experience with Google Cloud Platform Vertex AI or similar
  • Familiarity with DevOps & MLOps principles
  • Ph.D. in Machine Learning, the natural sciences, or similar
