About the Role

We’re looking for a Senior User Acquisition Manager to own and scale paid user growth, with a strong focus on Web-to-App funnels and consumer B2C subscription apps. You’ll lead strategy and hands-on execution across channels in a post-IDFA environment, working deeply with MMPs, SKAN, and AEM to drive sustainable growth.

This role is ideal for someone who has already scaled a consumer subscription app and is comfortable making decisions with imperfect attribution data.

Responsibilities

• Own end-to-end user acquisition strategy and execution across paid channels (Meta, Google, TikTok, etc.)
• Scale Web-to-App funnels, optimizing from landing page through install and trial start
• Drive growth for B2C subscription apps, focusing on trials, conversion, retention, and LTV
• Own MMP implementation and analysis (AppsFlyer, Adjust, or Branch)
• Set up and interpret SKAN measurement (conversion values, postbacks, modeled data)
• Design and maintain Meta AEM (event prioritization, attribution windows, reporting)
• Build and maintain blended performance reporting across platforms and attribution systems
• Partner closely with creative to define testing frameworks, messaging, and iteration cadence
• Continuously optimize funnels, onboarding flows, and paywalls in collaboration with product

Requirements (Must-Have)

• 5+ years of experience in user acquisition / performance marketing for mobile apps
• Proven experience scaling consumer B2C subscription apps
• Strong, hands-on experience with Web-to-App funnels
• Deep, practical experience with an MMP (AppsFlyer, Adjust, or Branch)
• Solid working knowledge of SKAN and post-IDFA attribution
• Strong understanding of Meta AEM
• Data-driven mindset with comfort operating under attribution uncertainty
• High ownership and ability to operate independently

What We Offer

• Full ownership over user acquisition strategy and execution
• Direct impact on growth, monetization, and product direction
• Competitive compensation with upside
• Remote-friendly, flexible work environment
