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.

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 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.

• Learning & Development budget, including time off for your self-development.
• Competitive financial package with equity, leave allowance, and health insurance.

• 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.
