We have hosted remote interns from several countries before. You will need at least 4 hours of overlap with US Central time. We use Slack, Notion and Google Meet. Cameras on for team calls.

Day to day:

• Engineer features from transaction, text or event data
• Evaluate models using precision, recall, AUC and other metrics that fit the problem
• Clean and prepare datasets in Python using pandas and NumPy
• Fine-tune small transformer models with Hugging Face for classification tasks
• Write prompts and evaluation sets for LLM features, and score the outputs

Requirements:

• Have a working laptop and a stable internet connection, ideally with a UPS backup
• Based anywhere in Pakistan
• Available at least 30 hours a week, with some flexibility during exam weeks
• Pursuing a degree in Computer Science, Statistics, Mathematics, Data Science or a related field, graduating in 2027

Preferred:

• Experience with PyTorch or TensorFlow
• Knowledge of NLP or computer vision basics
• Exposure to SageMaker, Vertex AI or Databricks notebooks

What you'll learn:

• Certificate and a recommendation letter, plus a pre-placement interview for strong interns
• Working with messy production data and real business constraints
• Experiment tracking and reproducible notebooks, the way the team actually does it
• How to judge whether a model is worth deploying, not just whether its accuracy is high
