Meet the team

At Preply, data is at the heart of every decision we make. We run hundreds of A/B tests to continually optimize our product, each with its own analytical and tracking challenges. The complexity of our marketplace, along with the unique dynamics of tutor-learner interactions, offers an exciting opportunity for those looking to make a real impact.

As a Data Scientist – Insights, you will be a key player in shaping the future of our product and driving our strategy forward. Embedded within the Self-Learning squad, you'll help launch and position a new AI-based speaking exercise. You'll provide insights to drive innovation, boost adoption and engagement, and help learners build confidence outside the classroom. Your work will shape how Preply evolves its self-learning experience, enabling learners to progress independently while reinforcing tutors' role in their journey. You'll collaborate closely with product managers, tech leads, designers, and other stakeholders to deliver insights that guide those strategic decisions.
