About the role

We’re building a high-velocity Apps Factory – a machine that launches, tests, and scales subscription mobile apps across multiple niches (health, wellness, utilities, education, astrology, AI tools and more).

Your mission as a Creative Producer is to turn insights, briefs and angles into scroll-stopping creatives that drive user acquisition across W2W and W2A funnels.

You’ll sit at the heart of performance + storytelling + production, working closely with Growth Marketing, UA and Product to ship and iterate winning concepts at scale.

This role can grow into Lead Creative Producer / Head of Creative Studio as we expand the portfolio and build a full in-house creative engine.

Why join us

• Create for impact, not for awards – you see results in ROAS, CTR, installs and revenue, not just “nice” campaigns.
• Work across many apps & verticals – new ideas, new audiences, no stagnation.
• High test velocity – dozens of variations, constant iteration, fast feedback from data.
• Play with formats – UGC, short drama, Reels/TikTok, motion, static, AI-assisted creatives.
• Be part of the core team – you’re not a service function, you’re a key growth driver.
• Career upside – help build the creative conveyor from scratch and later lead the team.

What you’ll do

• Turn growth briefs and hypotheses into clear creative concepts, scripts, and storyboards.
• Produce and manage UGC, influencers, actors, voiceovers, editors, designers where needed.
• Work with AI tools (image, video, script, VO) to speed up versioning and localization.
• Own the creative pipeline for your apps: from idea → test asset → winner → scalable pack.
• Collaborate daily with:
  • Growth Marketing – angles, messaging, offers, audience insights.
  • UA – formats, placements, specs, testing structure.
  • Product – alignment with funnel, paywalls, in-app experience.
• Maintain a structured asset library with tags (angle, persona, format, hook, language, app).
• Keep an eye on TikTok / Reels / Shorts trends and adapt them to our apps and markets.

In your first 3 months you will

• Deep dive into our apps, audiences and funnels (W2W & W2A).
• Take ownership of creative production for 1–2 priority apps.
• Ship multiple creative packs (AI + UGC + motion + static) and iterate based on results.
• Build a basic creative conveyor: simple process, clear stages, tagging, and feedback loop.

Ideal profile

• 3+ years in performance-driven creative: mobile apps, DTC, subscription products, or agencies.
• Strong skills in video-first formats (TikTok, Reels, Shorts, UGC-style content).
• You can turn a dry performance brief into a simple human story or hook.
• Comfortable working with creators / actors / editors and managing small productions end-to-end.
• Data-curious: you don’t have to be an analyst, but you care how your creatives perform and want to see the numbers.
• You like speed: test, learn, move on. Not months of polishing.
