What is an IT engineer? Introducing the job content and required skills

Characteristics of people who are suitable for becoming IT engineers include: liking IT technology, being interested in cutting-edge technology, liking concentrated work, being good at streamlining work, and being good at communication. Things like being good at something.
Many IT engineers are working as excellent IT engineers not only in science but also in liberal arts, and this is a position that is expected to continue to be in demand in the future. Also, even if you are not good at IT, you can create a chance to work as an IT engineer by acquiring industry knowledge or acquiring basic skills through self-study or school.

You may want to consider building your skills and career as an IT engineer through a temporary work style that allows you to work on a variety of industries and projects.

The main job of a system engineer is to build and design systems that meet client requirements, and the process can be broadly divided into the following three steps.

・Requirements analysis (hearing)
First, we begin by understanding the customer’s requests, which is called hearing. We conduct research through repeated discussions to find out what kind of system the customer is looking for and what they want to achieve. At the same time, we think about whether the system is possible or not and what specific work is required.

・System design
We perform the necessary system design. If the design is properly created, subsequent system creation work will proceed smoothly.

・System implementation
Once the system is constructed, we test it to see if it operates as designed. If a mistake is found during the testing stage, we go back to the initial hearing or design stage to investigate any mistakes or omissions and find the cause. Once we find the error or cause, we will make corrections and perform the test again.

In addition, system engineers may play the role of coordinating a team toward completion. In addition to system engineering knowledge, there are cases where the ability to absorb business knowledge and coaching skills is required.

A programmer is a position that creates efficient programs based on development specifications created by system engineers and is also called a software engineer. After implementing the program, test it. Even if a program is created according to the specifications, defects may occur, so in such cases, bugs and errors will be corrected.

In addition to having the programming language skills necessary for the project you are developing, you are also required to know quality control such as creating test specifications and failure management. Depending on your area of ​​responsibility, you may also be required to know networks and databases. Also, depending on the company, the jobs of system engineer and programmer may be held at the same time.

The job of a network engineer is to design, construct, operate, and maintain networks appropriate for the purpose and scale of the network. I am in charge of network-related systems such as routers, email systems, and firewalls, and my work also includes security measures to protect networks from unauthorized access. Additionally, when a network failure occurs, it is the network engineer’s job to find the cause and restore the network.

Network engineers must not only have basic knowledge of communication technologies such as TCP/IP and LAN but also be familiar with computers and peripherals, including the ability to interoperate servers, routers, etc. Additionally, with the spread of cloud environments, skills such as building networks for connection to the cloud and configuring cloud environments are also in demand.

A server engineer is a position that specializes in the design, construction, operation, and maintenance of server systems, and requires knowledge of server OS and security. In our design work, we estimate the specifications of the server that can withstand the system load, and design an efficient server system while also considering cost effectiveness.

Although it is often confused with a network engineer, a server engineer is in charge of applications that run servers, so their field of work is different from that of a network engineer, who is in charge of applications that connect to networks.

A database exists at the back end of every system, and databases are essential for the use of cutting-edge technologies such as big data. Databases are an essential part of IT systems. A database engineer is responsible for designing, building, and managing this database. Qualifications that certify skills include the national qualification “Database Specialist Examination” run by the Japan Information Promotion Agency, an independent administrative agency, and the private qualification ORACLE MASTER.

A web engineer is a person who specializes in the design, construction, operation, and maintenance of websites and web service systems. It is necessary to develop a web-based service system that takes into account the needs of users.

Web engineers are divided into front-end engineers and back-end engineers. Taking an e-commerce site as an example,
・Front-end engineer: Responsible for the movement and design code of parts visible to the user such as product pages
・Back-end engineer: Processes data purchased by users and outputs the results, etc. Responsible for developing systems that are invisible to users

Security engineers develop systems to prevent unauthorized use of systems and cyber attacks. In addition to constantly gathering new information from the market and updating our security systems, we also take action in the event of a breach.

Sales engineers are responsible for explaining systems to clients and answering questions. Using our knowledge as engineers, we also make proposals for the introduction of our own products and services from a professional standpoint. What makes me different from other IT engineers is that I am also in charge of sales, and my role also includes closing contracts.

IT assistants have a variety of jobs, including assisting the help desk team with research, assisting project managers with their work, compiling materials, and making communications. Since you have many opportunities to come into contact with professional staff, you can learn a lot while on the job, making it the perfect position to start your career in the IT industry.
