In this paper we describe how we designed a massive open online course (mooc) on Privacy by Design with a focus on how to achieve compliance with the eu gdpr principles and requirements in it engineering and management. This mooc aims at educating both professionals and undergraduate students, i.e., target groups with distinct educational needs and requirements, within a single course structure. We discuss why developing and publishing such a course is a timely decision and fulfills the current needs of the professional and undergraduate education. The mooc is organized in five modules, each of them with its own learning outcomes and activities. The modules focus on different aspects of the gdpr that data protection officers have to be knowledgeable about, ranging from the legal basics, to data protection impact assessment methods, and privacy-enhancing technologies. The modules were delivered using hypertext, digital content and three video production styles: slides with voice-over, talking heads and interviews. The main contribution of this work is the roadmap on how to design a highly relevant mooc on privacy by design and the gdpr aimed at an heterogeneous audience.
