## About the role

AI is already in production across our platform. Your job is to make it measurably better and add ML where rules fall short. This is a hands-on role: you'll write the code, run the experiments, and ship the models. We're hiring at the Senior or Principal level. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 6+ years in data science or applied ML (Senior), or 8+ (Principal), with models you shipped and maintained in production
- Strong Python and SQL, and large-scale data processing on a major cloud platform
- Experience evaluating and improving LLM or agent systems in production
- Hands-on experience adapting or training models for a specialized domain
- Anomaly detection or classification with rare events and noisy labels
- Solid statistics and experimental design, and the judgment to ship a simple baseline when it's good enough
