Welcome to GoodHabitz

We're one of Europe's fastest-growing EdTech companies, on a mission to make learning as fun and addictive as your favorite series. From bite-sized training to full learning journeys, everything we create is designed to inspire people to grow—both personally and professionally.

Behind the scenes? A team of curious minds, creative thinkers, and tech enthusiasts who love solving real problems and building products that truly make an impact. We move fast, think big, and don't take ourselves too seriously along the way.

About The Role
As a Senior Full Stack Engineer, you'll work across the entire stack—from backend services to frontend experiences, and everything in between. But this isn't just about writing code. You'll help shape how we build, contribute to architectural decisions, and collaborate closely with people across Product, Design, and beyond.

You'll take ownership, think in solutions, and bring others along in your reasoning—whether they speak fluent JavaScript or not.





What You Will Do
- Build and maintain features across the full stack—APIs, data layers, and user interfaces
- Contribute to architecture and system design, weighing trade-offs and helping the team make thoughtful decisions
- Own your work end-to-end: from idea to implementation, testing, documentation, and deployment
- Improve and maintain CI/CD pipelines and deployment workflows
- Review code with a focus on quality, clarity, and knowledge sharing
- Communicate technical decisions in a clear and accessible way, helping the team stay aligned—even when opinions differ

Requirements
- 5+ years of experience as a full stack engineer, working across both backend and frontend
- Strong experience building real products and collaborating with Product, Design, and UX teams
- A product mindset—you understand what creates value for users and the business
- Solid experience with Node.js, TypeScript, and React. E
