- Monitor partner performance, delivery, and revenue impact, proactively resolving complex campaign, technical, or commercial issues for high-value clients
- Stay current on ad formats, channels, platforms, tools, regulations, privacy requirements, ad verification, and broader ad tech trends to inform partnership strategy
- Act as a senior subject matter expert and force multiplier by sharing best practices, maintaining partner collateral and technical resources, and mentoring peers on inventory partnership excellence

What you’ll bring to the table:

- 3-5+ years of experience in business development, strategic partnerships, inventory development, or another partner-facing commercial role within digital advertising or ad tech
- Proven track record of cultivating strategic partnerships, opening new revenue streams, and increasing revenue or market share across multiple EMEA markets
- Understanding of the programmatic advertising ecosystem, including RTB, DSPs, SSPs, ad exchanges, private marketplaces, publishers, media owners, and regulatory considerations
- Strong analytical capability, with experience using market sizing, sales analytics, partner performance data, and strategic planning methods to inform commercial decisions
- Excellent communication and stakeholder management skills, with the ability to influence senior internal and external stakeholders, navigate complex negotiations, and articulate partnership strategy clearly
- Demonstrated ability to contribute to a high-performance culture while balancing strategic oversight with hands-on execution
