Job Description

As one of the core members of our product team, you’ll own end-to-end product experiences — from understanding the why behind a feature to building, shipping, and scaling it across classrooms.

You’ll collaborate closely with our CTO and teams across engineering, design, and product — ensuring what we build truly moves the needle for students and teachers.

You are:

  • Someone who thrives on solving real-world problems.
  • Someone who loves to learn, and levels up everyone around them.
  • Someone who communicates clearly, and values mutual feedback.

You will:

  • Build and ship full-stack features using TypeScript, React, Next.js, and Postgres.
  • Strengthen our core infrastructure for performance, reliability, and developer velocity.
  • Think deeply from the user’s perspective and understand the product direction.

Why join now:

This role is designed to be a launchpad for rapid growth and deep impact.

  • Impact. What you build will reach real classrooms quickly — and you’ll see the difference firsthand.
  • Growth. Join a tight-knit, fast-moving engineering team inside a growing 14-person company.
  • Focus. Work with clarity, autonomy, and rapid feedback loops.
  • Learning. We value learning — for students, and for ourselves.
  • Truth-seeking. We believe in finding patterns, digging deeper, and iterating relentlessly.

If you’re excited to shape the future of personalized learning and want to build products that make a real impact in classrooms, we’d love to hear from you.
