Meet the team!

The Platform Tribe builds and operates the platform that Preply engineers develop and deploy on, and that millions of learners and tutors rely on every day. Our platform handles over 20bln requests per month, and we combine software engineering, distributed systems and cloud infrastructure to keep it reliable at scale while making it faster and easier for engineering teams to build on top of it.

As part of the Developer Platform team, you’ll focus on:

• Developer experience and productivity: making it faster, simpler and more enjoyable for engineers to build and ship high-quality software.
• CI/CD and testing: evolving the systems and workflows that help engineers test, validate and deploy code quickly and confidently.
• Developer tooling and paved paths: building scalable tools and abstractions that reduce friction and enable teams to work autonomously.
• AI-native development: using AI and agentic workflows to rethink and improve how software is developed and shipped at Preply.
  
  

We work in small teams with significant ownership, so you’ll have a real say in architecture, technical decisions and how our platform evolves.

We have diverse technical challenges that will allow you to develop your skills across the stack - sometimes we write about them in our Engineering Blog! Please, also visit our Tech Radar and our YouTube channel to learn more about the technologies we use at Preply!
