We’re looking for someone to grow our revenue through third-party cross-sell offers. That means studying each product and its user journey, finding the moments where a related offer is genuinely useful, and placing products and services from partner companies there.

efaq.com - psychological, educational, and just-for-fun quizzes

Key Responsibilities

• Own the additional LTV generated through cross-selling, end to end

• Track and analyze how cross-sell offers perform and how they affect our unit economics, and keep improving placements and partner mix to grow revenue

Requirements

• 2+ years of experience in traffic monetization through affiliate or partner offers
• Strong understanding of the unit economics of subscription businesses
• Strong analytical skills: comfortable working with numbers and reasoning logically about data
• Proven experience negotiating with partners and third-party services to secure better offer terms
• English at C1 level

Would be a plus: experience with platforms like Rokt, MomentScience, Fluent, the Amazon Affiliate Program or other affiliate programs

Conditions
