Meet the team!

Our team builds scalable, resilient products using Python/Django on the backend and React on the frontend, all with one goal in mind: creating a smooth, meaningful experience for our learners and tutors.

We're proudly tech-agnostic, great engineers come from all kinds of backgrounds. Whether you've worked with Java/Spring, Node.js, Ruby on Rails, Scala/Play, PHP, or Go, you'll feel right at home here. Python experience isn't required.

We make decisions based on data and real user feedback: running A/B tests, shipping iteratively, and constantly improving. We also put a strong focus on observability, monitoring, and metrics, so we can keep our systems healthy and continue optimizing at scale.

At Preply, we ship 50-60 times per day, thanks to a solid CI/CD setup and a culture that values action over ceremony. As a fast-growing company, you'll find a wide range of technical challenges (we even write about many of them on our Engineering Blog!), the kind of work that keeps you learning, stretching, and growing.

We've reached 90%+ adoption of AI coding tools across engineering, and we're now moving towards more autonomous, AI-Augmented development at scale. At Preply, engineers have direct access to the best tools available, with the freedom to use them fully and experiment as they build.
