Primer is an online community where 7-14 year olds spend their time coding video games, writing their own books, and exploring nature.

Why join us?

  • We are working on one of the most important problems of our time: helping the next generation achieve their full potential.

  • We hail from companies like SpaceX, Square, Notion, Khan Academy, Stripe, Airbnb, and Coinbase. We're well funded by many of the top investors in our industry (Keith Rabois from Founders Fund, Naval Ravikant, Lachy Groom, Cyan Bannister, Balaji Srinivasan, Julia DeWahl, and many others), and are building a real business fueled by real revenue — not just venture capital.

  • We started Primer pre-COVID, and we are very focused on the long-term growth of homeschooling and other alternative education options, but we have also experienced very strong growth due to COVID-related school shutdowns.

Engineering team and processes

We strongly believe that small teams of exceptional engineers are orders of magnitude more effective and more fun to work with, so we're intending to keep our team small for as long as we can. We are a team of 4 right now: 1 iOS, and 3 full-stack web developers.

Technical Challenges

Building a new educational infrastructure will require to get a lot of things right—from obsessing over the tiny details of the product, to building ML recommendation engines and live video streaming infrastructure.

Projects you might work on
  • [iOS] Building fun ways for students to share project updates using AVFoundation, CoreImage, Metal, ARKit, and PencilKit (think: instagram stories, TikTok, snapchat)

  • [web] Building a feature that allows students to customize the CSS of their project journal pages.

  • [web] Building an internal tool that allows our education team to author new projects in Notion and then export them into our own rich component system.
