Data Science Intern, Spring 2027

Who we are:

Southside Cloud builds scheduling and dispatch software for field service companies, from two-truck plumbing outfits to regional HVAC contractors.

About the role:

We are building text classification and search features using LLMs and classic ML. The intern will help with experiments, evaluation and data labelling. Remote within the US. The team meets in Waltham once a quarter, travel covered. We do not have many meetings. Most updates happen in writing. You will write a lot of updates, so clear written English is important.

Day to day:

• Fine-tune small transformer models with Hugging Face for classification tasks
• Clean and prepare datasets in Python using pandas and NumPy
• Track experiments in MLflow or Weights & Biases so results can be reproduced
• Package a trained model behind a simple FastAPI endpoint for testing
• 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
• Pull data from BigQuery or PostgreSQL with SQL queries

What we're looking for:

• Available 40 hours a week for the full internship
• Currently enrolled in a bachelor's or master's program, graduating between December 2027 and June 2028
• Authorized to work in the US. CPT and OPT candidates are welcome to apply
• A GitHub repo or Kaggle notebook showing at least one ML project end to end
• Available at least 30 hours a week, with some flexibility during exam weeks
• Laptop with 8 GB RAM or more and a stable internet connection (no GPU needed, we provide cloud compute)

What you'll learn:

• Working with messy production data and real business constraints
• 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

Duration: 12 weeks

Start date: Spring 2027

Stipend: $47.00 - $53.50 an hour

What we offer:

• Paid company holidays
• Intern events and speaker sessions (virtual)
• Home office setup stipend
• Return offer opportunities

New hires usually start two to three weeks after accepting an offer.

Duration: 12 weeks. Start: Spring 2027.
