Meet the team!

As a member of the Platform tribe, the Site Reliability Engineer (SRE) at Preply combines software development, infrastructure operations and business skills to run a large-scale, fault-tolerant, global language education platform. The SRE ensures that Preply systems have high reliability, top-industry uptime and a fast rate of production innovations. Additionally, SRE’s keep an ever-watchful eye on the capacity and performance of our system.

We’re really serious about it: you’ll be able to actually measure how your work impacts business and present it to the whole company. We promote self-direction to work on meaningful projects, while we also strive to create an environment that provides the support and mentorship needed to learn and grow.

We release our product 70-80 times per day by leveraging modern technologies like Kubernetes, Docker and top-notch CI/CD processes.
