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.
