Programmer and System Analyst: There is no difference between advanced and low level. They are two occupations with completely different requirements for professional skills. Programmers, as the name implies, mainly write programs, which is a basic skill that computer majors need to practice. The skills of system analyst require him to know how to write programs, but his focus is on how to cut a large project into small pieces suitable for individuals and then organize these small pieces. The programmer's responsibility is how to realize these small pieces better and faster.
Hardware engineer: according to the project schedule and task assignment, complete the hardware development products that meet the functional requirements and quality standards;
According to the product design specification, design the logical design and schematic diagram that meet the functional requirements; Write a debugging program to test the developed hardware equipment; Prepare project documents and quality records.
Hardware test engineer: a professional post, he is responsible for testing hardware products to ensure the test quality and the smooth progress of the test work; Write test plans and test cases; Submit test report and write user manual; Participate in the improvement and formulation of hardware testing technology and specifications.
Software engineer: IT is the basic post of the whole IT industry. According to the development progress and task assignment, complete the design, development and programming tasks of the corresponding module software; Test program units and functions, find out the defects of software, and ensure the quality of software; Prepare project documents and quality records; Maintain the software to maintain its availability and stability.
Software testing engineer: Almost every large and medium-sized IT enterprise's products need a lot of quality control, testing and documentation work before release, which must be completed by skilled professional software talents. Software testing engineer is the key role of this kind of enterprise. At the same time, software testing is an important part of software development, which is responsible for testing the programs written by programmers and giving relevant modification opinions. Test engineers are generally divided into the following grades: junior test engineers, intermediate test engineers, senior test engineers and test managers. The salaries of test engineers at different levels vary greatly.
Technical support engineer: cross-industry post, responsible for technical support of platform, software and hardware; Responsible for user training, system installation and contact with users; Assist sales from a technical point of view. If subdivided, it can be divided into internal technical support and external technical support, and external technical support can be divided into two categories: pre-sales and after-sales. Pre-sales technical support is more inclined to product sales, and after-sales technical support is more inclined to engineer role.
Network engineer: mainly responsible for information security, system integration, data processing, configuration of switches and servers, establishment of local area network, network maintenance, integrated wiring, etc. Responsible for the establishment, debugging and maintenance of the internal network of the enterprise, optimize the network structure and provide network services for all departments; Specify network management rules, do a good job in fault prevention, and formulate emergency measures after the network is attacked; Use the network management platform to monitor the running status of network equipment, servers and other equipment; Participate in and guide the company's computer system construction, such as computer room construction, wiring, etc.
System engineer: System engineer is a delicate job, which requires enough patience and responsibility of practitioners.
The status quo has a certain grasp and solving ability.
Database engineer: responsible for the design, development and management of large databases; Responsible for the installation, configuration, monitoring, maintenance, performance adjustment and optimization, data conversion, data initialization and dumping, backup and recovery of the database in the process of software development and release, so as to ensure the smooth development of developers; Keep the database running efficiently and smoothly, and ensure the satisfaction of developers and customers.
Information security engineer: Information security engineer is mainly responsible for the implementation of information security solutions and security services; Responsible for the standardization of the company's computer system, specifying the standardization of the company's internal network and the standardization of computer software and hardware; Providing Internet security consulting and training services; Assist in solving safety technical problems in other projects.
Software Architect: In many companies, the architect is not a special formal position. Usually in a development team, the most experienced programmers will be responsible for some architectural work. In a department, the most experienced project manager will be responsible for some structural work. In fact, it is the overall designer of software, and the architect is trained by engineering practice. Software architect is a new profession in the software industry. His job is to translate the customer's requirements into standardized development plans and texts, formulate the overall framework of the project and guide the whole development team to complete the plan during the development of a software project. The main task is not to write specific software programs, but to engage in higher-level development framework work. It can be said that the architect's work determines the success or failure of the whole software development project.
