At Hasbro and Wizards of the Coast, you’ll collaborate with passionate teams to reimagine our iconic brands and create experiences that spark joy, connection, and community through the magic of play. This is your chance to shape legendary play that lasts a lifetime. We’re building something new inside our AI Studio, and we’re looking for a Full Stack Engineer to help build it with us. This role sits at the center of a new platform that is being actively designed and shipped. The architecture is still taking shape, and the integration surface is constantly expanding. What excites us is the opportunity to build the infrastructure that makes never-before-imagined character experiences possible. We work where storytelling, imagination, and technology converge. Our focus is on building the core platform: the APIs, the admin tooling, the service integrations, and the delivery infrastructure that makes AI-powered character interactions real. This work connects what brand and creative teams envision with what audiences ultimately experience. This role is foundational to everything the platform does. Working closely with the Engineering Manager and Principal AI Engineer, this Full Stack Engineer will own significant portions of the system end to end — from the tooling that configures and versions character behavior to the API layer that external partners and products consume. Success here means shipping features that hold up under real-world conditions and integrating reliably with the AI services that bring characters to life. What You’ll Do Design and build features for our AI character platform. This includes: the admin tooling, as well as the API layer consumed by external integrations and par

Nous travaillons à la croisée de la narration, de l’imagination et de la technologie.
