About the Role

We're looking for a Paid Social Ad Copywriter who loves turning ideas into high-performing ads and takes ownership of results. If you're passionate about short-form video, performance-driven creative, and storytelling—and enjoy collaborating with creators, influencers, and production partners—you'll thrive in this role.

You'll own the end-to-end creative process for paid social campaigns, using data and experimentation to develop ads that drive measurable business growth.

Responsibilities

  • Own Gakku's end-to-end social advertising creative process, from ideation and scripting to talent sourcing, production coordination, editing direction, and final delivery.
  • Develop high-performing paid social ads through compelling copywriting, creative storytelling, and strong visual execution.
  • Manage relationships with external agencies, creators, actors, and video editors to ensure efficient workflows and high-quality deliverables.
  • Analyze creative performance using data-driven frameworks and continuously optimize messaging, hooks, visuals, and overall ad effectiveness.
  • Identify winning creative patterns, scalable formats, and best practices to contribute to Gakku's advertising playbook and improve ROAS.
  • Stay up to date with social media trends, platform best practices, and emerging creative formats to keep campaigns fresh and competitive.

Preferred Qualifications

  • 2+ years of full-time experience in performance marketing, creative strategy, or growth marketing for consumer apps or at a marketing agency.
  • Experience marketing B2C mobile or web applications, such as productivity, education, language learning, marketplace, or subscription-based products.
  • Proven experience creating and optimizing paid social advertising creatives across platforms such as Meta, TikTok, and YouTube.
  • Strong analytical mindset with the ability to interpret performance data and translate insights into creative improvements.
  • Excellent project management and communication skills, with experience coordinating cross-functional teams and external partners.
  • Hands-on experience filming, editing, or producing high-quality video content is a strong plus.
  • Previous experience in management consulting or strategy & operations is a plus.

This Role Is Not a Fit If

  • Your experience is primarily as a freelance content creator without owning end-to-end marketing strategy or performance metrics.
  • Your background is focused on organic social media content without hands-on experience managing or optimizing paid advertising campaigns.

Work Arrangement & Compensation

  • Location: Fully remote (U.S. only)
  • Schedule: Full-time (40 hours/week) with flexible working hours, to be finalized with the hiring manager.
  • Employment Type: W-2 full-time employee with a comprehensive benefits package.
