At least in Switzerland those job titles are made up by the companies. Additionally since the Bolognia process people get a degree as Bsc or Msc. in Computer Science while the older degrees do contain the title prefix "Dipl. Ing ..." (e.g. Engineer with specialization in Software Development). So while the degrees are protected the job title are basically totally random.
