    Description

    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.

    The Preply Engineering Team provides the tools to help unlock human potential through learning.

Our team is made up of talented engineers who are passionate about solving complex problems and developing innovative solutions to drive our company's success.

  • Help us make our best practices even better (test culture, code reviews, monitoring and scalability of our tools);
  • Supporting the creation of new backend services as well as design, create, and/or troubleshoot integrations with third-party vendors.

    • What you need to succeed:

  • Proficiency in Python, having experience as a Backend or Full-Stack Engineer;
  • 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;
  • Expertise in troubleshooting issues, identifying the root cause, mitigating it, and adding setting up safeguards to prevent future issues;
  • High level of self-organization, ownership, and responsibility;
  • A great collaborator with excellent verbal and written communication skills. Minimum B2 English level;
  • Willingness to be on-call for your squad (1 week every 5 weeks).

    • Why you'll love it at Preply:

  • Open, collaborative, dynamic and diverse culture.
  • Generous monthly allowance for lessons on .
  • Learning & Development budget, including time off for your self-development.
  • Competitive financial package with equity and leave allowance.
  • Access to free mental health support platforms.
  • Opportunity to shape the lives of learners and tutors from over 175 countries through language learning and teaching.

    • Our Principles

  • Care to change the world - We are passionate about our work and care deeply about its impact to be life changing.
  • We do it for learners - For both Preply and tutors, learners are why we do what we do. Every day we focus on empowering tutors to deliver an exceptional learning experience.
  • Keep perfecting - To create an outstanding customer experience, we focus on simplicity, smoothness, and enjoyment, continually perfecting it as every detail matters.
  • Now is the time - In a fast-paced world, it matters how quickly we act. Now is the time to make great things happen.
  • Disciplined execution - What makes us disciplined is the excellence in our execution. We set clear goals, focus on what matters, and utilize our resources efficiently.
  • Dive deep - We leverage business acumen and curiosity to investigate disparities between numbers and stories, unlocking meaningful insights to guide our decisions.
  • Growth mindset - We proactively seek growth opportunities and believe today's best performance becomes tomorrow's starting point. We humbly embrace feedback and learn from setbacks.
  • Raise the bar - We raise our performance standards continuously, alongside each new hire and promotion. We build diverse and high-performing teams that can make a real difference.
  • Challenge, disagree and commit - We value open and candid communication, even when we don't fully agree. We speak our minds, challenge when necessary, and fully commit to decisions once made.
  • One Preply - We prioritize collaboration, inclusion, and the success of our team over personal ambitions. Together, we support and celebrate each other's progress.

    • Diversity, Equity, and Inclusion

    Preply is committed to creating a diverse and inclusive environment where people from all backgrounds can thrive. Different opinions and viewpoints are key ingredients in our success as a multicultural Ed-Tech company.
