This article explores the use of modern technologies to train pre-service specialists to work productively in smart cities in Ukraine. Firstly, the concept and main components of digital infrastructure as a training foundation for future professionals were identified. Next, training technologies were determined using the expert evaluation method. Subsequently, a survey was conducted among students and lecturers at higher education institutions. The results showed the most important factors of professional training. After applying these, a model for integrating training into a smart environment was developed, along with recommendations for its use. The research found that effective professional training programs for future smart city development specialists require cooperation among municipalities, universities, businesses, civil society organizations, and residents. Following implementation of the research, we concluded that the most useful training technologies were Smart Ukraine, the Lviv IT Cluster, the IT Ukraine Association, and the Association for Innovative and Digital Education. A variety of teaching methods were employed in pilot programs to demonstrate improved student skills, including problem-based learning, interdisciplinary projects, and VR/AR simulations. The research also highlights the importance of ongoing professional development in fostering innovation readiness.
