As AI becomes increasingly integrated into public sector services, identifying the professional profiles and competencies necessary for its responsible implementation has become a critical priority. This study investigates the specific skills, knowledge areas, and professional attributes required for the ethical and effective deployment of AI in public services. Drawing on empirical insights from an expert workshop and follow-up interviews, we propose a competency framework that emphasizes not only technical expertise but also policy, legal, and ethical dimensions. Our findings contribute to ongoing debates on workforce preparedness and educational program design for AI governance in both the public and private sectors.
