    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.
