Senior Manager, DSP Partnerships

London / Hybrid 

We’re looking for a commercially driven, strategically minded programmatic leader to help shape and grow our DSP partnerships across EMEA.

This is a high-impact opportunity to take ownership of key DSP relationships, particularly mid-tier and emerging platforms - turning potential into meaningful, scalable revenue. You’ll sit at the heart of commercial strategy, partner collaboration, and cross-functional execution, playing a visible role in shaping how we scale DSP demand across the region.

If you thrive on building strategic partnerships, leading commercial negotiations, and influencing growth outcomes in a fast-moving programmatic landscape, we’d love to speak with you.

What you’ll focus on

Growing Strategic DSP Partnerships

• Build and deepen relationships with emerging and strategic DSP partners, earning credibility with senior commercial and trading teams.


• Scale mid-tier and challenger accounts from early-stage engagement into consistent, material revenue contributors.


• Prioritise partnerships based on growth potential and long-term strategic value.


• Lead structured business reviews and forward planning conversations grounded in clear data, measurable goals, and shared objectives.

Commercial Leadership & Negotiation

• Own commercial discussions including supply agreements, incentive structures, and investment commitments.


• Develop clear revenue forecasts and business cases to support partnership growth and internal planning.


• Balance commercial confidence with long-term relationship building — knowing when to push, when to collaborate, and when to protect value.


• Communicate roadmap plans clearly and responsibly, aligning partner expectations with delivery realities.

Programmatic & Market Expertise

• Act as a trusted partner to DSP trading, supply, and product teams.


• Demonstrate strong understanding of programmatic buying across display, CTV, online video, and in-app environments.


• Confidently navigate conversations around auction dynamics, supply pathways, and performance drivers.


• Identify and help resolve performance challenges that may impact scale or efficiency.

Operational Execution & Cross-Functional Collaboration

• Partner closely with Product, Engineering, Customer Success, Legal, Finance, and Publisher teams to remove blockers and drive execution.


• Maintain operational rigour across onboarding, scaling, and troubleshooting.


• Ensure commercial commitments are realistic, aligned, and fully supported internally.

Market Insight & Leadership

• Stay close to programmatic market developments and evolving buyer needs to inform account strategy.


• Share actionable partner feedback that shapes product priorities and go-to-market direction.


• Bring strong judgement, commercial maturity, and a high level of ownership to a dynamic, evolving market.

We’d love you to have

• Significant experience in programmatic advertising, with a strong focus on DSP partnerships or demand-side commercial roles.


• A track record of growing strategic partnerships and delivering measurable revenue impact.


• Proven ability to lead complex commercial negotiations and structure mutually beneficial agreements.


• Deep understanding of auction mechanics, supply paths, performance optimisation, and the broader ad tech ecosystem.


• Strong forecasting, analytical, and business case development skills.


• The confidence to engage senior stakeholders internally and externally.


• A collaborative mindset with the ability to influence across cross-functional teams.


• A balance of strategic thinking and hands-on execution.
