About the Team Enterprise Marketing helps the world’s largest organizations understand, adopt, and scale AI. We create programs that bring OpenAI’s products, research, and perspective closer to the priorities, decisions, and work of enterprise customers. Some of the most consequential opportunities cannot be served by adapting an existing campaign, event, or playbook. They require a new model: a way for customers to experience what is possible, learn by doing, and turn insight into action. Our team builds and scales those models across markets. About the Role We are looking for a senior program builder to create differentiated executive and enterprise experiences. You will shape the experience thesis, build and test the first version, and help determine whether the work should become part of a broader repeatable program, remain bespoke, or stop. This role focuses on incubation: developing new experiences, strengthening consequential customer moments, and creating the principles and materials needed for durable ownership. Your initial focus will be helping bring a new flagship, hands-on enterprise customer experience to life in San Francisco, developing new executive and practitioner formats around it, and supporting selected strategic-account interventions where a differentiated approach is needed. This is a senior, hands-on individual-contributor role for a builder who combines customer and commercial judgment with original program design and excellent execution. You will work across Sales, Product Marketing, Product, Research, Solutions, Design, Events, Operations, regional marketing, and executive teams. You will be expected to make clear choices, build directly, and stay close to the work until the model is proven and ready for durable ownership. This role is based in San Francisco. We use a hybrid model of three days in the office each week and offer relocation assistance. Given the nature of the work, periods of more intensive onsite participation are expected
