As a category-defining company, we’re shaping what the future of learning looks like at global scale.

Meet the team!

• Collaborate closely with PMs, EMs, designers, and analysts to make data-informed, user-centered decisions.

• Champion engineering best practices: test automation, documentation, observability, and quality-first culture.

   

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);
• Proven experience leading complex, ambiguous, or greenfield projects end-to-end
• Strong communication and cross-functional collaboration skills (English level B2+)

• Willingness to be on-call for your squad (1 week every 5 weeks).

   

Nice to have

• Side projects or product ownership experience.
• Experience designing systems for marketing attribution, experimentation platforms, or recommendation engines.
• Familiarity with cloud platforms (AWS/GCP) and modern DevOps practices.
• Familiarity and willing to support small JS/TS tasks when needed.

Why you’ll love it at Preply

• An open, collaborative, dynamic, and diverse culture;
• A generous monthly allowance for lessons on Preply.com, Learning & Development budge,t and time off for your self-development;
• A competitive financial package with equity, leave allowance, and health insurance;
• Access to free mental health support platforms;

• The opportunity to unlock the potential of learners and tutors through language learning and teaching in 175 countries (and counting!)

   

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.com is committed to creating an inclusive environment where people of diverse backgrounds can thrive. We believe that the presence of different opinions and viewpoints is a key ingredient for our success as a multicultural Ed-Tech company.
