  • About Core

    Our mission is to cement mental wellness as a pillar of modern life. Our first product is a handheld meditation trainer, Core, that pulses in your hands to help you learn quickly and focus, and which analyzes heart rhythm to understand the state of the nervous system, infer what meditations work for you and chart your progress over time. Our first batch quickly sold out and organically attracted engagements with a Grammy-winning artist, NFL and PGA Tour athletes, Lululemon, Saks 5th Ave, and more. As we start down the path to shipping this product to a wider audience we need a senior Data Engineer to help us build the most advanced and effective product possible.
