Senior Customer Success Manager

Freestar is seeking a Senior Customer Success Manager to own complex publisher relationships and serve as a strategic advisor and yield expert. The role focuses on performance analysis and optimization, account growth and renewals, cross-functional collaboration, and mentoring other customer success managers.

Responsibilities:

• Own a portfolio of Freestar's more complex publisher accounts, serving as their primary strategic point of contact
• Lead executive business reviews with a clear point of view — not just a performance recap, but a forward-looking perspective on where the relationship should go
• Build deep, multi-threaded relationships within publisher organizations, spanning revenue, ad ops, product, and editorial
• Anticipate risks and opportunities before they're surfaced by the publisher, and come to every conversation prepared with a recommendation
• Take ownership of performance analysis end-to-end — identifying trends, forming hypotheses, designing tests, and tracking outcomes across your portfolio
• Drive more sophisticated optimization work: auction dynamics, floor pricing strategy, identity and audience approaches, format diversification, and the interplay between user experience and revenue
• Serve as a technical resource for both your publishers and your peers — able to go deep on programmatic mechanics and explain them clearly to any audience
• Collaborate with yield, demand, and product teams on bespoke solutions for accounts with unique needs or meaningful scale
• Identify and develop expansion opportunities that are genuinely additive — new products, formats, or services that make sense for each publisher's specific situation
• Contribute meaningfully to renewal conversations, bringing a clear account narrative and commercial instincts to the table
• Flag patterns you're seeing across your portfolio that could inform product development, demand strategy, or CS process improvements
• Mentor and support junior CSMs, sharing your experience and helping elevate the team's collective standard
• Help build and refine playbooks, QBR templates, and best practices based on what you're learning in your accounts
• Contribute to onboarding and training as a subject matter resource

Requirements:

• 5–8 years of experience in customer success, account management, or a publisher-facing role within ad tech or programmatic advertising
• Proven track record managing complex, high-value accounts with multiple stakeholders
• Deep, working knowledge of the programmatic ecosystem — header bidding, floor pricing, auction mechanics, yield optimization, GAM, and identity solutions
• Strong analytical instincts: you're comfortable owning performance analysis independently and turning data into a clear narrative
• Executive presence and communication skills — able to hold a room at the VP or C-suite level without leaning on a script
• A coaching mindset — you share what you know and make the people around you better
• Self-directed and proactive; you manage a complex book without needing to be prompted
• Experience on the publisher side — you've sat in the seat your partners are sitting in
• Familiarity with identity and audience solutions (UID2, RampID, first-party data strategies)
• Experience with CMP/consent frameworks and their downstream monetization impact
• Comfort with CS and CRM platforms and using data to manage a book systematically
