We help people discover the magic of the perfect tutor, craft a personalised learning journey, and stay motivated to keep growing. Our approach is human-led, tech-enabled
- and it's creating real impact.
We've just reached unicorn status with a $150M Series D, accelerating our vision to transform education through human-led, AI-enhanced learning. As a category-defining company, we're shaping what the future of learning looks like at integral scale.
Every Preply lesson sparks change, fuels ambition, and drives progress that matters. Joining Preply means helping define the future of education at global scale, and building something that truly matters for millions of people, every day.
Meet the TeamAt Preply, we build scalable and reliable applications using Python/Django, with a strong focus on data, A/B testing, and feedback from students and tutors to guide our decisions. We prioritize product quality through robust monitoring, metrics analysis, and continuous optimization. Our Platform Tribe builds and operates the internal products that make it simple, safe, fast, and reliable for engineers to deliver value. The platform is designed around opinionated, well-supported paved paths, self-service by default, and guardrails over gates.
You will work across platform squads (Infrastructure, Runtime and Data, Developer Platform, Application Platform, Frontend Platform, Mobile Platform) to set technical direction, unblock complex problems, raise the quality bar through mentorship, and ship production changes hands-on.
We've reached 90%+ adoption of AI coding tools across engineering, and we're now moving towards more autonomous, AI-Augmented development at scale. We have diverse technical challenges that will allow you to develop your skills across the stack
- sometimes we write about them in our Engineering Blog.
