Meet the team! The Security team partners across the company to help Preply grow safely and sustainably. We are responsible for platform security, application and product security, security operations, and incident response. We work closely with SRE, Data teams, Engineering teams, and our GRC function to make security practical, measurable, and scalable.

We work in small teams, which means you’ll have high ownership, real influence on technical decisions, and the opportunity to drive meaningful improvements across the company. We promote self-direction, strong collaboration, and a culture where trust and clear communication matter.

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! Please, also visit our Tech Radar and our YouTube channel to learn more about the technologies we use at Preply!
