About the Role

Permutive has built an advertiser business that works with some of the most innovative advertisers in the world. Our platform connects brands directly with premium publishers. Using the Permutive infrastructure for data collaboration, we enable audience activation that respects consumer privacy and is non‑reliant on an identifier to drive performance.

The role of Senior Manager, Supply Partnerships Manager is key to ensuring our success and will focus on managing the smooth supply operations of Permutive’s media practice. This role will be responsible for driving publisher business development of our curation media product and cleanroom activations, cultivating strong relationships with our publisher partners and managing the quality and efficacy of their supply signals within Permutive’s media offerings to advertisers. The ideal candidate will possess a deep understanding of the programmatic advertising landscape, strong analytical skills, and a proven track record of success in publisher‑facing roles.

What you’ll be doing

Reporting to the VP, Strategy & Operations, you will work closely with the Customer Success team and Ad Operations teams to ensure a smooth operational experience and revenue growth for publishers participating in Permutive’s media activations. This is a hybrid role; you’ll be responsible for maintaining relations with our publisher customers concerning media opportunities, while also acting as operational support for ongoing supply signal management and publisher reporting. You will also work closely with the partnership teams in forging strong relationships with the wider ad tech ecosystem, especially SSPs and DSPs.

Your day‑to‑day responsibilities will include

• Publisher Business Development & Growth:
  • Identify, prospect, and onboard new premium publisher partners, expanding our supply footprint across various verticals and formats (web, app, CTV, audio, etc.).
  • Develop and execute strategic account plans to grow existing publisher relationships, identifying opportunities for increased monetization and deeper integration.
  • Negotiate and finalize complex partnership agreements, ensuring mutually beneficial terms.
  • Act as the primary point of contact for assigned publisher accounts, providing exceptional service and proactive support.
• Supply Signal Management & Optimization:
  • Monitor, analyze, and optimize supply signal quality, identifying and addressing issues related to audience delivery to programmatic channels.
  • Collaborate closely with internal product, engineering, and operations teams to troubleshoot technical issues, implement new features, and improve overall supply performance.
  • Leverage data and analytics to provide actionable insights to publishers, helping them optimize their audiences and other signals.
  • Ensure compliance with industry standards and internal policies regarding data quality and privacy (e.g. GDPR, CCPA).
• Cross‑Functional Collaboration:
  • Work closely with Sales, Client Success, Product, Engineering, and Operations teams to ensure seamless integration and optimal performance for publisher partners.
  • Collaborate with demand‑side teams to understand advertiser needs and ensure a healthy balance between supply and demand.

What you’ll need

• A robust understanding of the Advertising ecosystem - DSPs, SSPs, CDPs - and how they all work together.
• Client Services experience managing and presenting to publisher accounts with Sales, Revenue and Ad operational leads. Ability to establish and maintain trust in a relationship with key stakeholders.
• A deep working knowledge of how a publisher ad stack works (for example, understanding the Ad Server / Pre‑Bid / Supply Side Platform).
• Can manage a level of ambiguity in a changing ecosystem and is able to adapt to positioning and messaging to market needs.
• Fantastic project management skills.
• Experience identifying & implementing new processes which have positively impacted internal or external stakeholders.

We’ll be excited if you also have…

• Hands‑on experience launching, managing and optimising campaigns for an advertiser in a publisher business.
• Exposure and experience working directly with brands and large media agencies.
• Experience explaining new and complex product suites to publishers, particularly product marketing, and positioning experience.

What we’re offering

We take a structured, objective approach to salary‑setting, which is based on market information, our compensation strategy, and your experience and capability as assessed through our interview process. For a typical candidate who meets our requirements, we would pay between £70,000 - £85,000 with a 20% performance bonus.
