Computer Solutions Developers and Designers fall under the ROME code M1805, which pertains to the profession of “computer studies and development.” They are responsible for designing, developing, and implementing an “IT application project, from the study phase to its integration, for a client or company according to functional requirements and specifications.” They might also lead development projects or coordinate teams.

According to APEC, the main factor influencing software development activity is technological: “Some developers specialize in very specific and advanced technology, while others are multi-platform developers.” The professional environment might also require these individuals to possess additional skills. For instance, developing a smartphone application involves different technical needs than designing an online video game. Hence, they can work under various job titles.
