## About the role

We're hiring a Founding Machine Learning Engineer to 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. That means working with LLMs, building evaluation systems to know when outputs are good (and when they're not), and shipping models that real scientists depend on every day.

## What they're looking for

- Bachelor's or Master's in Computer Science, Machine Learning, AI, or a related field (PhD is a plus)
- 2+ years building and deploying ML models in production
- Strong Python skills and hands-on experience with PyTorch, TensorFlow, or similar
- Real experience with LLMs: fine-tuning, RAG, prompt engineering, evals
- Experience working with large datasets and building data pipelines
- Familiar with AWS or GCP for model training and deployment
