Important Note

This is a B2B experiential marketing role. Successful candidates will have meaningful experience leading conferences, trade shows, executive events, customer and partner programs, sponsorships, hospitality, or other live business experiences, in addition to managing complex client relationships. Candidates whose experience is primarily consumer activation, shopper marketing, or production execution without B2B account and planning leadership are unlikely to be successful in this role.
