Sr Director, DSP Partnerships & Growth

OpenX is focused on unleashing the full economic potential of digital media companies. We do this by making digital advertising markets and technologies that are designed to deliver optimal value to publishers and advertisers on every ad served across all screens.

At OpenX, we have built a team that is uniquely experienced in designing and operating high-scale ad marketplaces, and we are constantly on the lookout for thoughtful, creative executors who are as fascinated as we are about finding new ways to apply a blend of market design, technical innovation, operational excellence, and empathetic partner service to the frontiers of digital advertising.

OpenX is seeking a strategic, commercially driven Senior Director, DSP Partnerships & Growth (Americas) to lead the regional DSP partnerships organization and accelerate revenue growth across established and emerging buying platforms.

• Execute DSP-focused demand diversification initiatives aligned with OpenX's broader demand strategy, expanding revenue opportunities beyond the largest established buying platforms.
• Identify, evaluate, and develop relationships with emerging DSPs and buying platforms, building a qualified pipeline of new commercial opportunities.
• Develop strategies to expand demand across CTV, mobile app, display, video, and emerging advertising environments.
• Identify opportunities to connect DSP demand with advertiser, agency, and publisher priorities through coordinated go-to-market initiatives.
