Jobs Poland

Readdle is a pioneering force in the personal productivity space on Apple devices, having shaped the landscape since 2007. Our mission is to empower individuals and teams with innovative technology, enhancing their efficiency and creativity. We are dedicated to crafting exceptional mobile and desktop experiences for those who aspire to achieve more.

As we scale Documents to new platforms and channels, we’re entering an exciting new stage of growth where great advertising creative becomes essential. To make this journey successful, we’re looking for a Senior Creative Producer to build and scale how ad creatives are produced across the company.

What will you do:

• Lead the Advertising Ideation Roadmap: Own the systematic generation of 10 to 15 unique marketing angles and visual concepts per week, transforming consumer psychology and user pain points into highly structured testing frameworks.
• Drive Asset Lifespan Optimization: Deconstruct active ads into modular pieces—such as isolating the first 3-second intro hook from the main body copy—and execute systematic component-swapping tests to continuously lower CPA and prolong ad scaling windows.
• Define Technical Briefing Standards: Author highly itemized, frame-by-frame storyboards and scripts for motion designers that detail precise platform safe zones, aspect ratios, audio tracks, and copy overlays to ensure seamless production execution.
• Build the External UGC Network: Manage the end-to-end sourcing, casting, and usage contract negotiations with user-generated content (UGC) creators, building a dependable pipeline of raw video assets for the post-production team.
• Own Creative Operational Infrastructure: Establish and automate the creative production task pipeline, leveraging standardized asset naming conventions and automated file storage configurations to maximize team velocity.
• Translate Quantitative Insights into Design Priorities: Partner directly with UA and analytics teams to evaluate downstream campaign performance metrics—specifically 3-second hook rates, CTR, CPC, and CPA—to steer subsequent design sprints toward high-performing visual directions.
• Execute Daily Competitive Audits: Monitor the Meta Ad Library, TikTok Creative Center, and interactive ad networks to identify emerging visual formats and monetization mechanics, directly utilizing these trends to feed the Stream 3 web-validation loop.

About you:

• At least 3 years of experience in a Creative Producer or similar role.
• A proven track record of consistently generating lots of fresh ad concepts, built on a real understanding of what makes people tick.
• Hands-on experience optimizing ads at the component level — testing and swapping hooks, intros, and bodies to bring CPA down.
• You can write detailed, frame-by-frame briefs and scripts for motion designers, including formats, dimensions, audio timing, and text overlays.
• You’re fluent in performance data — hook rates, CTR, CPC, CPA — and know how to turn it into your next production priorities.
• Experience sourcing, casting, and negotiating usage contracts with UGC creators.
• You’ve owned creative production systems before — naming conventions, organized file storage, and task management.
• You know your way around the Meta Ad Library, TikTok Creative Center, and other ad-intelligence tools to study what competitors are doing.

Nice to have:

• Familiarity with AI generation tools (Midjourney, Kling, Runway) so your briefs fit modern design workflows.
• Experience marketing B2C utility or productivity apps, turning complex features into simple consumer angles.
• Light hands-on editing in Premiere Pro, After Effects, or CapCut for quick mockups or rough cuts.
• Some exposure to web landing pages and web-first conversion flows.
