About Core

At Core, we believe in taking an active and intentional approach to building your inner strength. Our first product, the Core meditation trainer, launched January 6th, and won a 2020 CES Innovation Award. It is the most immersive meditation experience: combining an app, a handheld device, biofeedback and fresh, updated content from our new Core Studio in downtown San Francisco. Our product is quickly selling out, and our beta organically attracted engagements with a Grammy-winning artist, NFL and PGA Tour athletes, Lululemon, Saks 5th Ave, and more.

What you'll do

  • Collaborate with mobile developers to support features and integrate them with cloud services 
  • Build and maintain a production grade server, database, and content system 
  • Develop and refine an integrated subscription accounts management system across checkout, app, and web interface.
  • Take our server-mediated streaming and content distribution capability to the next level.
  • Ensure we've got our database and API set up to be maximally efficient and elegant.
  • Support analytics and A/B testing efforts
