## About the role

We're hiring a Machine Learning Engineer Intern to help build the AI systems that power our platform. The core challenge: take a natural language query from a biologist and turn it into a correct, reliable bioinformatics workflow. You'll work with LLMs, experiment with prompt engineering and fine-tuning, and help build evaluation systems to measure when the outputs are actually good.

## What they're looking for

- Currently pursuing or recently completed a Bachelor's or Master's in Computer Science, Machine Learning, AI, or a related field
- Strong Python skills
- Familiarity with ML frameworks (PyTorch, TensorFlow, or similar)
- Basic understanding of LLMs and modern AI techniques (fine-tuning, RAG, prompt engineering)
- Some experience working with datasets and building data pipelines
- Can think critically about when an LLM output is actually correct
