The Preply Engineering Team provides the tools to help unlock human potential through learning. We implement A/B tests to prove the value of our initiatives and improve our product based on data and students and tutors feedback. As part of our commitment to ensuring high-quality products, we prioritize monitoring and metrics analysis to identify areas for optimization and ensure our services are performing at their best.

We are tech-agnostic, meaning we are open to considering candidates with diverse technology backgrounds, such as Java/Spring, Node.js/Express.js, Ruby/Ruby on Rails, Scala/Play, PHP, or Golang. While Python is our primary programming language, prior experience with it is not mandatory. What truly matters is your enthusiasm for learning Python and your ability to adapt quickly to using it for product development.

• Develop and own backend features using Python/Django, supporting the creation of new backend services as well as design, create, and/or troubleshoot integrations with third-party vendors.
• Balance short-term speed of development with the long-term technical quality of our systems.
• Leverage your experience to guide the team in making informed technical decisions, such as continuous improvement of best practices (test culture, code reviews, monitoring and scalability of our tools).
• Exposure to architectural patterns of a large, high-scale web application (e.g., well-designed APIs, high-volume data pipelines, efficient algorithms).
• Familiar and willing to support small JS/TS tasks when needed.
