What is an engineer? A diverse and specialized profession
An engineer is a professional who utilizes specialized knowledge and skills in engineering to design, develop, and improve products and systems. Generally, engineer occupations can be classified into "development engineers" and "infrastructure engineers."

When working as an engineer and advancing in your career, it is important to understand how companies view the job of engineers. Even though the term "engineer" is used in general, the job content is subdivided, and the skills required and the companies that require them vary greatly.

The occupations of engineers can be broadly divided into "development engineers" and "infrastructure engineers."

Development engineers are generally thought of as engineers who are "responsible for designing and developing individual applications, services, and the systems required for machine operation." Examples of development engineers include " markup engineers " who write HTML and CSS for websites, "mobile application engineers" who program smartphone apps, and "control and embedded engineers" who develop systems installed in home appliances and machines.

On the other hand, infrastructure engineers are engineers phone number library who are responsible for the design, construction, and operation of the systems that serve as the common foundation for a variety of IT services. Examples of such engineers include network engineers who build, maintain, and manage networks, and security engineers who can design and build systems that take information security into consideration.

Additionally, there are other types of engineers, such as "sales engineers" who support sales activities from a technical perspective, and "in-house systems engineers (help desk)" who are responsible for the operation and maintenance of applications and systems used within the company.

Another thing to remember is that engineers are called different names depending on their role (how they relate to the work). There are classifications such as "programmers" who are in charge of the programs themselves on-site, "system engineers (SE)" who are responsible for everything from system design to programming, and "project managers" whose responsibilities include progressing system development and managing resources and budgets.
