Want to join a world-class tech team building the systems that power immersive learning worldwide?

You’ll be part of the team that builds the underlying systems powering Attensi’s global learning experiences, used by hundreds of thousands of users worldwide.

This is a full-stack JavaScript role with a strong backend focus. You’ll work primarily on backend services and APIs built with Node.js and TypeScript, and contribute to frontend features in our superuser apps using React or Vue when needed.

What You Will Do

• Design and build secure, scalable applications using Node.js and TypeScript with and without AI

• Work with technologies like PostgreSQL, Redis and Kafka
• Take part in discussions about capacity planning, performance and security
• Help operate and improve our live production environments
• Collaborate in small, cross-functional feature teams to build innovative learning experiences

Our backend infrastructure runs on AWS and includes technologies such as Node.js, Ruby on Rails, .NET Core, PostgreSQL, Redis, Kafka, Kubernetes, and ArgoCD. You don’t need to know everything; strong fundamentals, curiosity and a willingness to learn matter most.

Who You Are

• Solid backend development experience with Node.js/TypeScript
• Experience with other languages like Python, Ruby, or C# is also valuable
• Good understanding of design, scalability and industry best practices
• Experience with, or interest in, frontend development using React
