Principal Agent Experience Designer

As a Principal AX (Agentic Experience) Designer at OutSystems, you will pioneer an entirely new design discipline, one where the user is no longer mainly human. You will define how AI agents navigate, operate, and succeed within our platform, while ensuring human oversight remains clear, trustworthy, and seamless when needed. This role sits at the frontier of the UX - UAX - AX evolution. Traditional UX designed for humans navigating screens. User-Agent Experience (UAX) designed for humans and agents co-navigating. Agentic Experience (AX) designs for agents operating autonomously. You will lead the internal and external AX frontier while bridging all three eras. Working closely with Product Management, Engineering, AI teams, and Research, you will transform our platform into an agent-ready substrate: machine-legible, safe by design, observable by default, and cost-aware. The Mission: Move beyond chatbots and design the world's first truly agent-operable development platform.
