Ruby on Rails Developer

Who We Are

At PlanetSpark, we’ve turned communication into a movement. What started as a vision to help kids speak with confidence has now become a global platform with over a million live classes across 13 countries. From storytelling to debating to launching their own YouTube channels, we’re helping the next generation find their voice. And we’re profitable, growing, and doubling down on AI to make it all even more powerful.

What You’ll Do

We’re looking for a full-stack engineer who wants to build products that matter. You’ll design and ship features for our core learning platform and shape AI-driven tools that give real-time feedback, personalize lessons, and unlock confidence in learners worldwide.

The work you do here won’t sit quietly in a backlog, it will be live in classrooms and homes, helping kids grow into communicators who change the world.

Tech Stack Overview

• Ruby on Rails on the backend
• React (with some ERB views) on the frontend
• PostgreSQL and Redis for data and caching
• Sidekiq for background jobs
• AWS for infrastructure
• AI-driven personalization layered across the platform

Our Culture

We run on high performance and high trust. We’re a mission-driven team that collaborates hard, ships fast, and holds each other to high standards. Engineers here own features end to end from the first sketch to production deployment. We’re as excited about mentoring each other as we are about scaling systems.

How You’ll Grow

In your first six months, you’ll launch features that touch thousands of learners. You’ll play a role in shaping how our AI adapts to kids’ voices, stories, and ideas. And as we scale, you’ll have the chance to step up whether that means leading architecture, mentoring teammates, or diving deeper into product strategy.

What We’re Looking For

Why Join Us

We’ve built a platform that’s profitable, global, and mission-driven. We’re not asking you to just write code, we're asking you to help us build the future of communication.
