Overview

As part of the Hardware department at Tonal, the Firmware team helps build our intelligent fitness system from the ground up. We enjoy the opportunity to develop a great product and to expand our technical breadth in the process. The Firmware team works across several embedded domains from wireless sensors to high powered motor control. We leverage embedded processors running anything from bare metal to Android using a variety of sensors, motors and communication paths to create a device that can deliver an exceptional user experience. Our system has many unique requirements around how to use motors to deliver such an experience and we are looking for a passionate and motivated Firmware Engineer generalist with a strong background in controls systems to drive the quality of our motor control systems higher and higher while being able to contribute to other domains as well.
