AI Data Scientist - Routing & Product Analytics

OpenRouter, Inc; Northern (KY); Hybrid; USD 100,000 - 140,000; Full time

Job summary

OpenRouter, Inc is seeking a Data Scientist to build the intelligence layer powering routing and analytics for the world’s largest model marketplace. You will work with product and engineering to translate data into features and insights that guide routing, usage optimization, and product strategy.

You will own end-to-end questions—from framing problems to shipping insights that influence routing heuristics, analytics products, and roadmap decisions.

Qualifications

• 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.
• 4+ years of relevant experience in a data science, applied ML, or quantitative product role at a high-growth, high-velocity company.

Responsibilities

• Build and improve the rules, heuristics, and models that drive our core model routing and provider routing systems.
• Build analytics products and conduct deep-dive analyses that empower users to understand usage, diagnose issues, and optimize workflows while informing our product strategy.
• Design and ship user-facing data features, from task-type classification taxonomies to public rankings pages that break down model performance by use case.
• Define and track product metrics such as feature adoption, user engagement, and platform health, directly tying these insights to roadmap and architectural decisions.
• Contribute meaningfully to the data warehouse (dbt, ClickHouse) to ensure the analytical foundation scales with the business.
