About the role**

You will lead the team responsible for building and deploying the machine learning models at the heart of Trustly’s transaction decisioning—determining whether each transaction is approved and guaranteed. Your work will directly influence how we manage risk, prevent fraud, protect our customers, and deliver fast, reliable payment experiences at scale.

This is a hands-on leadership role. You will develop and ship production-ready models yourself while setting the technical direction for a team of data scientists and machine learning engineers. You will mentor and grow the team, establish strong modeling and experimentation practices, and take end-to-end ownership of its work—from roadmap and development through deployment, monitoring, and continuous improvement.

You will partner closely with Risk, Product, Engineering, and Finance to translate complex risk challenges into practical machine learning solutions and measurable business outcomes.
