Job description

We are currently looking for:

A hands-on Growth Marketer to own the full go-to-market strategy for an exciting consumer app launch. You'll be joining at a pivotal moment - pre-launch - meaning you'll have real ownership over how this product reaches the market. We're looking for someone who has been through an app launch before, thrives in a fast-paced environment, and knows how to drive user acquisition across both paid and organic channels. If you're data-driven, action-oriented, and ready to hit the ground running, we want to hear from you.

Key Responsibilities

  • Develop and execute a full go-to-market strategy for a consumer app launch
  • Own paid and organic acquisition channels: social, search, ASO, influencer, PR
  • Define KPIs, track performance, and iterate rapidly based on data
  • Work cross-functionally with product, design, and leadership
  • Build launch campaigns and community/buzz pre-launch

Experience & Skills

  • Proven experience launching a consumer app (end-to-end, from pre-launch to scale)
  • Strong grasp of growth loops, retention mechanics, and funnel optimisation
  • Hands-on with paid social (Meta, TikTok), Google UAC, and analytics tools
  • Data-driven mindset with a bias for action
  • Immediately available or very short notice

At Riverflex, we offer an integrated service through three service pillars: strategy & transformation consulting that Creates Change, talent services that Build Teams, and business-accelerating products that Augment Intelligence.
