Software Developer Jobs in O Fallon, IL

Design and build applications that run on computers or in web browsers. Software developers may specialize in specific software applications or underlying systems that run devices and networks. Developers consider the users’ needs and the capabilities of the technology being used in order to tailor software to best fill those needs. When planning how each part of the software will fit together, they often create flowcharts and other models/diagrams. These graphics are helpful when constructing or demonstrating the application’s functionality.

Software developers are responsible for ensuring that their programs continue to function correctly through various tests. They also document the software’s features so that the records can be referenced during future maintenance and upgrades.
