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.
