• Fluency with the metrics that actually run a VIP book: NGR (not just GGR), cohort-based LTV, LTV:CAC, bonus efficiency, and surplus margin.
• Experience leading through a manager layer rather than running a desk personally — comfortable setting direction and holding a Team Leader accountable to KPIs, not doing the coaching yourself.
• Strong cross-functional influence — you've shaped Product, Marketing, and Compliance decisions with data, not just requested changes.
• Working knowledge of the regulatory constraints that shape VIP marketing in T1/T2 markets (e.g. UK affordability checks, MGA/EU advertising rules, responsible gambling obligations).

🎓 Education & Experience:

• Bachelor’s degree in Business, Marketing, or a related field.
• A minimum of 3 years of experience in VIP management or a similar role, with at least 2 years in a leadership position.
