Overview

Remote ML internship focused on real company data, not Kaggle datasets. Most of the time goes into cleaning data and checking whether a model actually helps. Fully remote. You can work from anywhere in Sweden. Normal business hours, Monday to Friday, with some flexibility. You will need a reliable internet connection and a quiet place to work.

Day to day

• Engineer features from transaction, text or event data.
• Write prompts and evaluation sets for LLM features, and score the outputs.
• Train baseline models with scikit-learn and compare them against simple rules.
• Evaluate models using precision, recall, AUC and other metrics that fit the problem.
• Track experiments in MLflow or Weights & Biases so results can be reproduced.
• Label and review samples of training data to check quality.
• Run exploratory analysis and write up what you find in a Jupyter notebook.
