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.

We work primarily with Python/Django to build scalable and robust applications. 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. 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.

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.

Meet the team!

The Frontend Platform squad is a part of the Platform tribe responsible for growing our business by:

  • providing our product squads with the infrastructure they require
  • improving developer productivity within product squads
  • maintaining high reliability of our services
  • doing projects and handling issues that are company-wide so a single product squad can hardly address them by themselves

We achieve those goals through:

  • Providing an excellent development environment. It’s fast and reliable. Transpilling, type checking, linting, and formatting help engineers write better code.
  • Providing tools that save time for engineers. It can be anything from coding some global utility functions to automating processes.
  • Making sure engineers can use technologies that help to achieve business goals. E.g. server-side rendering, GraphQL clients, Storybook and others are set up. Node.js, Next.js, React and other technologies are updated to the needed versions.
  • Making sure CI/CD is fast and stable and proper production monitoring is set up. Together with SRE team work on delivery and testing pipelines, improving observability on production.
  • Owning company-wide testing tools. We provide tools that enable teams to write all sorts of tests, to make them fast and reliable (especially tools for e2e testing).
  • Helping to keep high standards of engineering practices at Preply. Contribute to the hiring process, knowledge sharing, engineering community etc.
  • And others.

  • Helping teams to make their e2e tests more stable.
  • Set up monitoring for the startup time of the local development server.
  • Lead the process of upgrading React, Next.js versions.
  • Analyze whether Yarn solves specific issues better than PNPM.
  • Build a babel plugin that enables copywriters to launch AB tests on copy (text in an app) w/o the involvement of engineers.
  • Implement canary deployments for FE services.
  • Setup caching of node_modules on CI.
  • Make builds of FE services environment independent.
  • Conduct knowledge-sharing sessions and workshops.
  • Iterate over our goals and metrics that define success.

What you need to succeed:

  • Exceptional problem-solving skills (e.g. sometimes it’s better to achieve a goal w/o coding).
  • Pragmatic and data-obsessed attitude for making technical decisions.
  • Strong leadership skills, aligning multiple people and teams towards common goals.
  • Moving forward with little supervision and in high uncertainty.
  • Growth mindset.
  • At least 5 years of experience in commercial software development.
  • Expert knowledge of JavaScript, ReactJS, and related web technologies.
  • Proven experience working in infrastructure teams would be a plus.
  • Nice to have: TypeScript, GraphQL, NextJS, Docker, Node.js, k8s, terraform, Jenkins
  • Minimum B2 English level.

Why you’ll love it at Preply:

  • Open, collaborative, dynamic and diverse culture.
