Position summary

As part of Group 219 — the collaborative network behind Church+State and Substance — the Digital Media Specialist is a hybrid media and project management role based in the C+S Toronto office. You will support the Substance Montreal media team in executing end-to-end digital and 360° campaigns for English-market clients, while serving as the primary Toronto point of contact. You’re equally comfortable building a media strategy as you are owning a client relationship, managing a budget, or walking into a pitch room.

You’re responsive, organized, and a productive, positive member of the team. You don’t take yourself too seriously and you love to work hard and have fun.
