Senior Customer Success Manager - Media
- London, UK

- 8th March 2026
Full Description
THE ROLE:
We're looking for an experienced Senior Customer Success Manager on the Client Services team, who defines the ‘’farmer’’ mentality – someone who thrives on nurturing deep-rooted relationships and harvesting long-term value from a sophisticated book of business.
In this role, you won’t just be managing accounts, you will be the lead architect of their growth. You’ll manage our highest-value clients, navigating the complexities of programmatic and multi-channel digital media to ensure their investment yields maximum returns. If you are a strategic thinker who sees a client objective and immediately starts mapping out a 12-month evolution plan, we want to talk to you.
Primary focus is on transforming a top-tier book of business into a thriving ecosystem of growth. You will be responsible for retention, but more importantly, for the expansion and diversification of our footprint within each account.
This is not a “maintenance” role. We are looking for a growth-oriented professional who views a stable account as a platform for innovation and expansion.
Key Responsibilities
- Strategic Account Planning: Developing and executing on comprehensive plans that aren’t just static documents. You will evolve these plans regularly to align with shifting client KPIs and market trends
- Revenue Growth: Identify untapped opportunities within existing accounts. You’ll lead the charge on upsells and cross-sells by demonstrating how new channels or programmatic strategies solve specific business hurdles
- Programmatic Subject Matter Expertise: Act as a consultant on multi-channel strategies (Display, Video, Social, CTV, etc.). You must be able to speak the language of performance data and attribution
- Executive Presence: Build “high and wide” relationships. You should feel equally comfortable presenting QBRs to CMOs while remaining a trusted partner to a mid-level stakeholder
- Churn Mitigation: Proactively identify “at-risk” signals and deploy recovery strategies before they impact the bottom line.
WHAT YOU’LL BRING:
- Experience: 5+ years in Customer Success or Account Management within the AdTech or Digital Media space
- Proven Success: in managing a customer portfolio and exceeding client expectations.
- Programmatic Fluency: Deep understanding of the programmatic landscape, including DSPs, SSPs and the nuances of multi-channel execution
- The “Farmer” DNA: You enjoy the process of building trust over time and find satisfaction in seeing a client’s spend and sophistication grow under your watch
- Analytical Rigor: You can look at a campaign dashboard and extract a narrative, not just a set of numbers.
- Resilience & Agility: A willingness to pivot between high-level strategy and tactical execution at a moment’s notice
- Sector Expertise: Previous experience managing RMG (Real Money Gaming) or iGaming clients is highly welcomed and will be a significant advantage.
About the Client Services team
Our team thrives because we look out for one another. We’re looking for someone who finds as much satisfaction in mentoring a teammate as they do in closing a growth deal. To us, no task is too small if it contributes to our clients’ success—so while you’ll be leading top-tier accounts, you’re also someone who doesn’t mind rolling up your sleeves for campaign audits or administrative needs. We believe in expertise without ego; we share our 'secret sauce,' we troubleshoot together, and we celebrate every win as a team.
We enjoy an ‘office-first’ culture and maximize opportunities to collaborate, connect and learn together. Our hybrid working models differ depending on your role and location.
One team, being brave, driving change
