Senior Python Software Engineer

CodeIT is a service product development company. We know how to transform business ideas into profitable IT products. We are looking for a skilled and experienced Python/Devops Engineer to join our team.

Project description

The project is a hosting platform operated by an established data center company that is evolving toward a more cloud-oriented service model. The core infrastructure is already in production and serving real customers, with ongoing improvements and expansion of cloud capabilities. 

Some existing products (such as CDN and VPS) are already live and stable. CDN is currently in a maintenance phase, while VPS is operational and requires continuous improvements, scaling, and optimization. Most core technical decisions for these services have already been made, and the systems are functioning in production. 

At the same time, new cloud-oriented services are being actively designed and developed — including Application Vending Machine, Kubernetes-as-a-Service, App-as-a-Service, and other infrastructure automation solutions. These areas provide more architectural influence and room for technical ownership.
