At Preply, we are unlocking human potential through learning.

We believe learning with a great tutor is life-changing. That’s why we match online tutors from across the globe with learners and empower them to create live language classes with AI-powered tools and learning materials. This is how we deliver progress, create engagement and keep our global community of learners motivated. So far, over 32,000 tutors have given more than 15 million lessons to learners from over 175 countries.

Meet the team!

Part of the Platform Tribe, the Developer Experience team at Preply combines software development, infrastructure operations, and business skills to continuously improve and maintain state-of-the-art dev experience at Preply.

At Preply we believe that DevExp is crucial for the healthy growth of an engineering organization. Currently, we release our product 70-80 times a day with avg lead time for new features less than 24 hours. We impact the work of more than 100 product engineers and have a noticeable impact on company performance.

DevExp team focus on 3 main areas:

  1. Improving feedback loop (responsiveness and stability of stage environments, local development, etc)
  2. Decreasing cognitive load (Improving documentation practices, unifying dev practices, decreasing change failure rate)
  3. Improve flow state of engineers (minimizing distractions and increased autonomy of product teams)

We work in small teams, thus you will be able to influence system design and contribute a lot in the company's growth. We’re really serious about it: you’ll be able to actually measure how your work impacts business and present it to the whole company. We promote self-direction to work on meaningful projects, while we also strive to create an environment that provides the support and mentorship needed to learn and grow.
