Senior Director, Platform Partnerships New York

Senior Director, Platform Partnerships (North America) The Senior Director, Platform Partnerships (North America) is a senior leadership role responsible for driving the strategic direction and growth of Index Exchange’s demand-side partnerships across the North American market. Based in New York, this is a high-impact, highly visible position that sits at the intersection of strategic partnership embedding, signal intelligence, commercial deal architecture, product intelligence, people leadership, and technical expertise. This is not a relationship management role. It is a demand activation role. The Senior Director must be able to operate credibly across all four of the team’s core jobs simultaneously: diagnosing and closing signal gaps that limit DSP bid quality; structuring and activating commercial deals; building joint growth agendas that shape DSP buying behavior; and routing DSP product intelligence into Index’s planning cycle. They must model what great looks like — because the team does not yet have that example internally. This role requires a leader who can operate at both the strategic and executional level — setting vision, coaching talent, and personally managing complex partner relationships. Travel across North America required. Responsibilities Signal Intelligence Understand how each DSP’s algorithm scores, evaluates, and bids on Index inventory.

Understand each DSP’s commercial priorities, the verticals they are scaling, the advertisers they are chasing, and how Index complements their motion in market.
