NLP Intern

About us:

Since 1927, the company has built manufacturing sites in County Dublin and abroad. We employ 620 people across research, clinical development, manufacturing and commercial teams.

The internship:

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. Our team is spread across 17 countries. Headquarters is in Dublin. The internship is fully remote. Interns join our Dublin team on daily calls and get a named mentor. Working hours overlap with UK business hours. We use Slack, Notion and Google Meet. Cameras on for team calls.

Day to day:

• Engineer features from transaction, text or event data
• Run exploratory analysis and write up what you find in a Jupyter notebook
• Write prompts and evaluation sets for LLM features, and score the outputs
• Evaluate models using precision, recall, AUC and other metrics that fit the problem
• Document assumptions, data sources and results in Confluence or Notion
• Present findings to the team in a short slide deck every few weeks
• Label and review samples of training data to check quality
• Clean and prepare datasets in Python using pandas and NumPy

What we're looking for:

• Have a working laptop and a stable internet connection
• Can start immediately or within two weeks

• Available at least 30 hours a week, with some flexibility during exam weeks
• Clear written English, since most discussions happen in docs and Slack threads
• Familiar with Jupyter or Google Colab

Preferred:

• Exposure to SageMaker, Vertex AI or Databricks notebooks

What you get out of it:

• Weekly mentorship from a senior data scientist
• 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
