As a Programmatic Media Assistant Manager at MediaOne , General Motors’ in-house media agency, you’ll play a pivotal role in leading programmatic strategy and optimization for some of the world’s most iconic automotive brands. You sit at the intersection of strategy, performance, and influence —shaping test agendas, raising the bar on activation quality, and steering how programmatic shows up across display, online video, CTV, audio, and emerging formats. This role is equivalent to an AMD/Director level at a media Agency. You will not have direct people management responsibility, but you will strongly influence the work and development of Programmatic Specialists and Senior Specialists through standards, guidance, and day‑to‑day collaboration. You’ll partner closely with brand media leads, performance marketing, audience and analytics teams, and platform partners to ensure our programmatic investments work harder and smarter for Chevrolet, GMC, Buick, Cadillac, OnStar, and GM corporate initiatives .
