We power people’s progress.
At Preply, we’re all about creating life-changing learning experiences. We help people discover the magic of the perfect tutor, craft a personalised learning journey, and stay motivated to keep growing. Our approach is human-led, tech-enabled — and it’s creating real impact.
We’ve just reached unicorn status with a $150M Series D, accelerating our vision to transform education through human-led, AI-enhanced learning. Today, 100,000+ tutors teach 90+ languages to learners in 180 countries — and we’re only getting started. As a category-defining company, we’re shaping what the future of learning looks like at global scale.
Every Preply lesson sparks change, fuels ambition, and drives progress that matters. Joining Preply means helping define the future of education at global scale, and building something that truly matters for millions of people, every day.
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.
