1. What is a Data Scientist at Tonal?
As a Data Scientist at Tonal, you sit at the unique intersection of hardware engineering, software development, and human physiology. Tonal is not just a connected fitness device; it is an intelligent, AI-driven strength training system that uses electromagnets, advanced sensors, and personalized algorithms to deliver dynamic weight resistance, track user form, and prescribe personalized workouts. Your role is critical in translating millions of data points from physical workouts into actionable, real-time feedback that helps users get stronger, stay safe, and remain engaged.
The impact of this position is felt across the entire product ecosystem. Whether you are developing algorithms to detect muscle fatigue, building personalization engines to recommend the perfect weight for a bicep curl, or analyzing user retention trends, your work directly shapes the user experience. You will collaborate closely with product managers, firmware engineers, and exercise scientists to turn raw telemetry data into intuitive, life-changing digital fitness experiences.
This role requires a balance of rigorous scientific thinking and rapid product execution. Because Tonal collects highly specialized data—such as high-frequency force and velocity measurements—you will tackle modeling challenges that do not have off-the-shelf solutions. To succeed, you must be comfortable navigating ambiguity, designing robust systems, and translating complex physical phenomena into elegant mathematical models.
