What You'll Do:

Join Nexxen's Client Success team, where you'll manage a portfolio of client accounts in close partnership with Strategic Sales, supporting campaign performance, retention, and day-to-day client communication. You'll serve as a key point of contact for your clients — using data and insights to inform campaign recommendations and ensuring smooth execution across managed service and PMP campaigns. This role will be based in the London office. Our team follows a hybrid schedule working in-office three days a week and remotely for the rest. This is an exempt position.

Each day can be different here at Nexxen, but some of the things you can expect to be doing daily are:

  • Manage a portfolio of clients in partnership with Strategic Sales, supporting the relationship end-to-end
  • Own the full campaign lifecycle — from kick-off call and strategy recommendation through to asset collection, optimisation, and performance reporting
  • Use data, market trends, and audience insights (including Nexxen Discovery) to support tailored campaign recommendations and upsell opportunities
  • Collaborate with Trading, Ad Ops, and Supply teams to troubleshoot campaign performance and deliver solutions that meet client needs
  • Communicate proactively with clients on pacing, performance, and reporting to maintain strong retention and satisfaction
  • Maintain accurate campaign tracking across Salesforce and internal systems

What You'll Bring:

  • 1+ years of experience in digital media, client services, or account management

Growing understanding of the programmatic ecosystem (DSPs, SSPs, targeting, measurement) and ability to translate data into actionable insights

  • Ability to manage multiple accounts and stakeholders simultaneously while supporting campaign performance and client goals
  • Strong communication and organisational skills with a proactive, client-first mindset
  • Experience working with Salesforce or similar CRM/campaign tracking tools
  • Comfortable collaborating cross-functionally to troubleshoot and problem-solve

Extra Credit if you bring:

  • Exposure to CTV, advanced TV, or programmatic video campaigns
  • Familiarity with audience strategy tools and data-driven planning (e.g. Nexxen Discovery Insights or similar)
