We’re on a mission to combine the magic of the best tutors with cutting-edge AI to create personalized journeys that keep learners motivated and inspired.

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

Our team leverages the powerful combination of Python/Django and ReactJS to engineer scalable, resilient applications that provide our users with an exceptional and seamless experience.

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.

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. 

At Preply, we release our product 50-60 times per day by leveraging top-notch CI/CD processes. As a fast-growing company we have diverse technical challenges (sometimes we even write about them on our Engineering Blog) that will allow you to develop your skills at scale. 

What you’ll be doing:

You will work in a cross-functional team alongside the Product Manager, Product Designer, UX Writers, Data Analytics, Technical Leads, Engineers and other cross-functional team members to deliver engaging features through A/B tests and build top-notch products, including, but not limited to:

  • 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.
  • Think beyond the code and about our customers, understand their needs, and define solutions with the team;
  • Balance short-term speed of development with the long-term technical quality of our systems;
  • As a Senior Engineer, you will 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). 

What you need to succeed:

  • 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 Preply.com .
  • Learning & Development budget, including time off for your self-development.
  • Competitive financial package with equity, leave allowance, and health insurance.
  • Access to free mental health support platforms.
  • Access to Gympass-partnered wellness and gym centers throughout Spain to promote and support well-being and physical health
  • Opportunity to shape the lives of learners and tutors from over 175 countries through language learning and teaching.
