Join our Tribe Fraud as a Data Scientist/Machine Learning Engineer and help protect our customers and society from fraud!

The Team

Within our Tribe Fraud NL you will work in a squad of Data Scientists focusing on fraud detection. We detect fraud in all channels of ING retail bank, including cards, online banking and mobile banking. The environment and challenges we face in the field of fraud change daily. Our goal is to be always one step ahead. With every new iteration and every new insight, we make the bank safer and protect our customers from fraud.

The Data Science squad is responsible for developing and maintaining fraud detection models. We strive to make these future-proof and scalable, and have them complement expert-based rules. The team is an ambassador of data science in the fraud domain and actively participates in the data science community. In this team you will contribute to ING being the safest bank and a leading player in fraud detection.

Our data science workflow has been maturing over the years, with higher standards for coding, testing and documentation. Model development, deployment and monitoring has been significantly improved. However, there is still plenty of room for improvement, which is why we are looking for a Machine Learning Engineer to take our data science to the next level.

Roles and responsibilities

We are looking for a medior or senior Machine Learning Engineer to enable data science in fraud detection. You will work with data scientists to develop machine learning models and other data science solutions, while having a focus on the engineering aspects. This includes:

  • building and/or maintaining:
    • machine learning models;
    • tooling for model development;
    • data processing and validation;
    • pipelines for model deployment
    • model performance monitoring;
  • working with other teams to integrate solutions into production systems, such as a real-time fraud detection engine;
  • applying best practices, such as testing, version control, four-eyes, and coding standards;
  • providing support to and explaining best practices to colleagues;
  • documenting models and other components;
  • doing administration to comply with data, model and IT governance;
  • being aware of trends in fraud and banking.

The team works in a hybrid way, meeting up together in Amsterdam for one day a week, while working remotely the rest of the week.
