Are you the explorer who will help us conquer new territories? Do terms like CPMs, SPO, and margin management get your adrenaline rushing? Do you speak fluent DSP, SSP, and Ad Server? At WPP Media in Amsterdam, we are growing rapidly and looking for an International Supply Pioneer / Negotiation Manager to take our programmatic supply strategy to the stratosphere. You'll drive international growth by securing commercial agreements with publishers in non-Dutch markets, balancing rock-solid relationships with razor-sharp commercial deals.

What you will do:

• Commercial Settings: Secure agreements with international publishers, analyze inventory value, create rate cards, and spot new market opportunities.
• Relationship Management: Maintain and elevate publisher connections while managing expectations around volumes, quality, and demand.
• Operational Control: Monitor total spend across active markets, lead troubleshooting for technical supply snags, and ensure all deals are fully approved before going live.
• Curation & SPO: Curate supply and optimize the Supply Path (SPO) for key strategic international clients while maintaining strict quality inclusion lists.
• Margin & Innovation: Monitor margins across programmatic channels and identify areas for continuous supply innovation following WPP Media best practices.

Dit krijg je van ons:

• Impact & Autonomy: A responsible, challenging role with significant freedom to develop and implement your vision within a top-tier client portfolio.
• Open Culture: A collaborative, international environment with hybrid working flexibility across our campuses.
• Compensation & Perks: 26 holiday days per year, 8% holiday allowance, hybrid working allowance (€30 net p/m), and a BYOD phone allowance (€57.50 net p/m).
• Benefits & Office Life: Collective health insurance, full travel expense reimbursement, affordable canteen lunch options, an on-site barista, and unlimited access to the M-Academy for continuous learning.

What you bring:

• At least 3+ years of experience in (programmatic) supply or campaign management (e.g., as a programmatic trader working with DV360 or The Trade Desk).
• Solid understanding of the digital media landscape in the local and EMEA region, with fluency in DSPs, SSPs, ad exchanges, and ad servers.
• Strong analytical and math skills, paired with excellent communication, writing, and time-management abilities.
• Experience in deal negotiation is a major plus.
