Summer Data Science Intern

About us:

Customers who call us usually reach someone who wrote the code they are asking about. Atlantic Software is a 30-person software shop in Toronto. The founders still answer support tickets.

About the role:

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. This is a remote internship. You will work with our team in Toronto, and the stipend is paid monthly in local currency. Expect to work a schedule that overlaps with US Eastern business hours until about noon ET. Clear written English is a must, as the team works across time zones.

Responsibilities:

• Engineer features from transaction, text or event data.
• Train baseline models with scikit-learn and compare them against simple rules.
• Package a trained model behind a simple FastAPI endpoint for testing.
• Pull data from BigQuery or PostgreSQL with SQL queries.
• Label and review samples of training data to check quality.

Requirements:

• Currently enrolled in a bachelor's or master's degree, graduating 2026 or 2027.
• Eligible to work in Sweden.
• Based in Sweden for the duration of the internship.
• Available for the full internship period.
• Pursuing a degree in Computer Science, Statistics, Mathematics, Data Science or a related field, graduating in 2026 or 2027.
• Working knowledge of SQL.
• Basic statistics: distributions, hypothesis testing, sampling.

Preferred:

• Experience with PyTorch or TensorFlow.
• Understanding of A/B testing.
• Kaggle competitions or a published student research paper.

What you get out of it:

• How to judge whether a model is worth deploying, not just whether its accuracy is high.
• You will take one model from raw data to an evaluated prototype.
• Experiment tracking and reproducible notebooks, the way the team actually does it.
