Experience building dashboards, reports, testing frameworks, and practical KPIs that creative teams can use to make publishing decisions.

Once post-production delivers a short, this team will develop and test four to five versions across Instagram Trial Reels and Facebook A/B tests, using performance data to identify the strongest opening hook, pacing, ending, and overall edit. This role owns the testing process from the first hypothesis through final recommendation, ensuring the version we publish has the highest probability of success. HOW YOU'LL SPEND YOUR TIME: Own each short after post-production and carry it through testing, iteration, and final optimization before public release. Create four to five strategically different versions of each short, including alternate hooks, openings, pacing, story structure, calls to action, and endings. Manage testing assistant to set up Instagram Trial Reels and Facebook A/B tests, then run follow-up tests when the first results reveal additional opportunities. Review hook rate, retention charts, drop-off points, completion rate, engagement, and other platform signals to diagnose where viewers lose interest. Recommend and execute edit changes based on the data, including requesting new voiceover from Dhar when a stronger test requires it. Create clear reporting systems that track every version, hypothesis, result, learning, next step, and final publishing recommendation. Compare test performance with live-post performance to develop KPIs and minimum thresholds that increase the probability of a successful public release., The Head of Testing will report directly to the Head of Shorts. WHO YOU OVERSEE: The Head of Testing will oversee one Testing Assistant and lead the day-to-day workflow of the Shorts Testing Team. ## Related Videos - [How I use public learning to kickstart my career - From marketing to full-stack in a 100 days](https://www.wearedevelopers.com/videos/579-how-i-use-public-learning-to-kickstart-my-career-from-marketing-to-full-stack-in-a-100-days) - [Keep your code refactorable](https://www.wearedevelopers.com/videos/381-keep-your-code-refactorable) - [Bringing the power of AI to your application.](https://www.wearedevelopers.com/videos/1010-bringing-the-power-of-ai-to-your-application) - [The Innovation Formula: Fast Prototyping, Data Analysis, and Real User Insights](https://www.wearedevelopers.com/videos/1421-the-innovation-formula-fast-prototyping-data-analysis-and-real-user-insights) - [Coffee with Developers - Adam Wiggins](https://www.wearedevelopers.com/videos/919-coffee-with-developers-adam-wiggins) - [Beyond Autocomplete: Local AI Code Completion Demystified](https://www.wearedevelopers.com/videos/961-beyond-autocomplete-local-ai-code-completion-demystified) ## Related Articles - [What Developers Really Need to Create Great Code Demos](https://www.wearedevelopers.com/magazine/658-what-developers-really-need-to-create-great-code-demos) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Top Tech YouTube Channels for Developers in 2023](https://www.wearedevelopers.com/magazine/261-top-tech-youtube-channels-for-developers-in-2023) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 130 - The Diablo is in the details](https://www.wearedevelopers.com/magazine/470-dev-digest-130-the-diablo-is-in-the-details)
