A marketing materials design developer is responsible for the creation and production of marketing collateral. This can include brochures, flyers, posters, signage, and other printed materials. The developer works with the marketing team to understand the objectives of the campaign and develop creative solutions that achieve these goals. They must have a strong understanding of branding and be able to translate this into visually appealing designs. In addition to being creative, the developer must also be highly organised and efficient in order to meet deadlines and budget constraints.
