Buyer Development Sr Director DACH

OpenX is looking for a senior, commercially driven Buyer Development leader to establish and grow our demand-side business across DACH.

The successful candidate will open senior buyer relationships, build and manage pipeline, progress strategic opportunities, and convert demand-side engagement into measurable revenue outcomes.

• Maintain strong commercial discipline around pipeline, forecasting, revenue progression, and opportunity prioritisation.

• Build the Market
• Establish OpenX’s Buyer Development presence in DACH as the first dedicated in-market hire.
• Create a clear map of priority buyers, agencies, holdcos, brands, DSPs, data partners, senior decision-makers, trading models, and commercial pathways.
• Identify where OpenX can create the most meaningful and scalable impact in the region.
• Build the foundations for a future regional team, including account prioritisation, pipeline discipline, market feedback loops, and cross-functional ways of working.
• Work Cross-Functionally
• Work closely with Sales, Account Management, Product, Marketing, global Buyer Development, DSP Strategic Partnerships, and the Data Partner function to shape, activate, measure, and scale DACH opportunities.
• Partner with DSP Strategic Partnerships to improve buyer access, support SPO conversations, and ensure agency and client demand can be activated efficiently through priority DSP routes.
• Partner with the Data Partner function to identify relevant data-led opportunities for DACH buyers, including curated marketplaces, audience-led activation, and strategic client solutions.
• Build OpenX’s Market Presence
• Represent OpenX as a credible senior voice in the DACH programmatic market.
• Support OpenX’s visibility through senior meetings, client education, industry events, roundtables, and thought leadership.
• Position OpenX around key buyer priorities including transparency, sustainability, premium supply, curation, data quality, supply path optimisation, and a healthier digital advertising ecosystem.

Requirements:

• 7+ years of experience as a senior commercial individual contributor with deep knowledge of the DACH programmatic advertising ecosystem and a strong network across agencies, holdcos, brands, DSPs, and strategic partners.
• The ideal candidate will have a proven track record of revenue ownership, opening senior relationships, building pipeline, and converting strategic opportunities into commercial outcomes.
