A backend developer develops what is "under the hood" of an application or website, the part invisible to visitors. Companies usually don't post jobs simply for a "Backend Developer", but specify the technology in the title of the position ( for example, PHP Developer or Ruby Developer).
Backend developers work with databases, web servers, server scripts, and APIs. These specialists are also responsible for integrating most of the services with your website. It is thanks to backend developers that things such as sharing on social networks, reCAPTCHA, online payment, and the ability to check card balance work. It is in the backend where processes are automated. In general, only a very simple static website can be built without a backend developer.
What should a backend developer know?
It would be a plus if the specialist understands the principles of UNIX systems and can draw up technical specifications.
The set of skills depends on the tasks. On a small project, it may be sufficient to know PHP (or even Node.js) Ajax and be able to work with a single DBMS. For a large online store, you need a mastery of technologies such as Docker, Kubernetes, experience with high loads, and knowledge of the monitoring systems.
