Our team builds scalable, resilient applications using the powerful combination of Python/Django on the backend and ReactJS on the frontend — all to deliver an exceptional, seamless experience to our users.

We’re proudly tech-agnostic, meaning we’re open to candidates with a variety of technical backgrounds, whether that’s Java/Spring, Node.js/Express, Ruby on Rails, Scala/Play, PHP, or Golang.While Python is our main language, prior experience with it isn’t required. What matters most is your willingness to learn, your ability to adapt quickly, and your enthusiasm for using Python in product-focused 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.

• 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 setting up safeguards to prevent future issues;

• High level of self-organization, ownership, and responsibility;

Why you’ll love it at Preply:

• An open, collaborative, dynamic, and diverse culture;

• A generous monthly allowance for lessons on , Learning & Development budget, and time off for your self-development;
