Line of business

IT solutions designers and developers can work in various structures, and mostly: in local authorities, private companies, public companies/institution, consulting firm, digital services companies or even in video game development. As video game designers, they can also work in communication agencies, PR and direct marketing agencies, advertising agencies, press, graphic design, animation or freelancing. Finally, they can operate in various lines of business such as administration/government service, the army, IT and telecommunication, software development, maintenance of existing applications and design of new software, multimedia publishing or computer hardware.

Available jobs

IT solutions designers and developers belong to the ROME M1805 certification which includes “computer studies and development” trades. Their job is to design, develop and finalize a “computer application project, from study shift to integration for a client or a company following functional needs and specifications”. They can also lead development projects and coordinate teams.

According to the APEC, the main variability factor in the software development trade is a technological one: “some developers are specialized in a very specific and edgy technology while others are multiplatform”.  The professional environment can demand additional skills from these people. For instance, developing a smartphone application doesn’t require the same technologies as an online video game. In this capacity, they can take different positions.
