About the Role

As a Data Scientist (Machine Learning, Statistics), you’ll be one of the first hires focused on building the experimentation and evaluation framework for our new enterprise ML product.

This role is core to defining how we measure success: from pre-deployment testing to live user impact analysis. As a Data Scientist, you’ll bring statistical rigor and clarity to noisy real-world data and help establish how we track quality, safety, and performance.

This is a good role for you if you:

• Have deep experience in applied statistics, experimentation design, and analysis
• Have built or contributed to evaluation systems for ML, with emphasis on safety, quality, or real-world impact
• Are confident designing and interpreting A/B, multivariate, and sequential experiments
• Can write data pipelines in Python using tools like pandas, NumPy, and statsmodels
• Want to shape foundational processes for evaluating large-scale machine learning systems

Responsibilities include:

• Design and run experiments to measure model behavior, user experience, and product quality
• Define and track key performance metrics to guide iteration and inform strategic decisions
• Work with ML researchers to evaluate fine-tuning and training results using robust statistical methods
• Build dashboards and tools to monitor product and model performance over time
• Help define benchmarks and evaluation standards across the organization
• Design simple, intuitive UIs for non-technical users to explore and act on complex data
• Create interactive visualizations that reveal key patterns from high-dimensional datasets
