Company at a Glance
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 looking for a senior, commercially driven Buyer Development leader to establish and grow our demand-side business across DACH.
This is the first dedicated Buyer Development role in-market. The role will be directly responsible for generating revenue across agencies, holdcos, and clients / brands, building senior relationships and commercial foundations required for long-term growth.
The successful candidate will open senior buyer relationships, build and manage pipeline, progress strategic opportunities, and convert demand-side engagement into measurable revenue outcomes.
This is a senior individual contributor role to begin with. As the DACH opportunity matures, the ambition is for this person to help build and potentially lead a broader regional Buyer Development function once clear market proof points have been established.
