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:

• 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.

What you will get at Readdle:

• Customer-centric culture. We put our users at the heart of everything we do. Every team member has the opportunity to engage directly with customers, gaining insights that shape meaningful, delightful experiences for millions worldwide.

• Exceptional people, exceptional team. Our greatest strength is our people. We care deeply about each other, work transparently, and celebrate collective success. Together, we build an environment where everyone can do their best work and grow beyond their potential.
• Real impact. We design products that truly matter. Our focus is on delivering tangible value, simplifying complexity, pushing boundaries, and continuously improving how we build and deliver solutions to our users.

About the project
 

US-founded media company operating email newsletters at scale – millions of subscribers across finance, health, and business verticals. Small engineering team, flat structure, direct ownership, fast iteration. No layers of approval, no large org to navigate.

• Agent systems coordinating multi-step operational tasks: content, QA, validation, reporting

Requirements

• 4+ years of production Python
• 2+ years shipping production systems with LLMs and agents
• Solid understanding of what happens underneath the frameworks: tokenization, context windows, function calling, when RAG helps and when it doesn't
