Senior Engineer - React and VR Development - Remote

Overview

At FitXR, we’re building the future of fitness - immersive workouts which turn movement into play, not punishment. We’re for the misfits: the ones who’ve always felt a little out of place in traditional fitness spaces. This is a new kind of community where movement is inclusive and everyone belongs.
