About the role
As a Data Scientist, you will build the intelligence layer that powers how millions of developers and AI agents interact with the world's largest model marketplace. OpenRouter processes billions of LLM generations spanning every major model, provider, and use case. Your job is to turn that data into a better product and a better experience for our customers.
What they're looking for
- Experience building and shipping production-level data products such as models, algorithms, classifiers, scoring systems, or automated processes
- Proven ability to partner with engineering and product teams to convert insights and analytics into customer facing features
- Strong SQL skills. You can write complex, performant queries against large-scale analytical databases (ClickHouse, BigQuery, or similar)
- Deep fluency with AI and agents. You use LLMs and AI tools in your daily work, understand how they behave, and have informed opinions on model evaluation, prompt engineering, and the agentic ecosystem
- Excellent statistical and mathematical foundations. You think in distributions, causal inference, and experimental design, not just averages and dashboards
- Proficiency in Python (or similar scripting language). You can prototype models, run simulations, and build data pipelines
