Senior/Lead Data Scientist -CreditJob detailsEngineeringMilanFull-time€65,133 EUR - €93,142 EUR**What you will do**
You will work on some of the most technically interesting modelling problems in fintech, training large transformer-based models on long sequences of real-world transactional events. You will design tokenisation schemes for numerical, categorical, and temporal features, making deliberate decisions about vocabulary size, sequence length, and information compounding. Your work spans the full model lifecycle from data preparation through to production and you will translate research decisions into systems that set the direction for how machine learning operates across Klarna. You will be part of a small, high-ownership team where what you build has genuine impact on the products Klarna ships.
**Who you are*** Deep understanding of transformer architectures and sequence modelling, with the ability to reason through architectural tradeoffs* Hands-on experience designing tokenisation schemes for heterogeneous feature types such as numerical, categorical, and temporal* Proficiency in Python, PyTorch, SageMaker, and Airflow* Experience owning the full model lifecycle, from training through to serving in production* Comfortable working in a small, high-ownership team on open-ended technical problems**Awesome to have*** Experience with Triton kernels or GPU-level optimisation* Broader ML background spanning areas beyond deep learning* Experience with large-scale transactional or financial data* Background in ML infrastructure or MLOpsPlease include a CV in English #J-18808-Ljbffr
