What is the main difference between system administrator and system engineer ?

It's very simple, engineer does design and develop the system i.e. Design the interface, writing codes. And his job is finished once software is accepted. Here the game starts for a system administrator, He will look after and responsible to keep the system running smooth, hardware, securities, data storage etc.

System Administrator - It's a admin kind of work where you support the whole IT infrastructure of the company.(Support Role)

System Engineer  - A Engineer who designs, develops the application and provides the service for the existing applications and software. 

 

Systems Administrators

Systems Administrators are expected to be efficient in diagnosing and fixing problems fast and with accuracy. It is essential for a system administrator to have a substantial understanding of various programming languages used for computing various tasks. In addition, they should be able to understand the nature of the software, to organize and use it for troubleshooting. A systems administrator needs to have intense knowledge about computer security. The job involves deployment of software patches and the deterrence of break-in and other security related issues, along with preventive measures. 

Systems EngineeringSystem engineering is one of the most lucrative careers in the field of computer technology and involves the realization and deployment of successful systems. It combines several disciplines and specialty groups and forms a well-organized development process, proceeding from the concept to the production and operation. The use of computers benefits both the business, as well as the technical needs of the customers and provides quality products that meet the specified needs of the user. While civil engineers design buildings and electrical engineers design circuits, a system engineer works with abstract systems and depends on other engineering disciplines to develop and deliver many tangible products.

network engineer design the network infrastructure and and system engineer just implement those infrastructure just in a office 

System Administrator would be management with technical skills (IT guy, keeps the servers up and running basically). System Engineer would be mostly technical with some management (Guy who designs and/or develops information systems).

Over the years, the demand for system engineers has been increasing. The job of a system engineer is basically to authenticate assumptions and come up with workable theories. Even extremely complex systems like aircrafts are modeled and simulated by system engineers. In addition to having a promising career in various companies, organizations and aviation, systems engineers also have job opportunities in power plants, the medical machinery and spacecraft industry. Efficient system engineers are hired in these industries to assure normal functioning of the various complex systems and to avoid unnecessary complications. They also work towards cost efficiency and providing assurance for quality improvement and success of a project.
