Junior Video Editor

Labhouse is a fast-growing startup that builds, launches, and scales its own AI & Productivity Apps, operating under a subscription-based business model.

Based in Barcelona, Labhouse was founded by Andrés Bou and Horacio Martos (Co-Founders of SocialPoint).

We operate at the intersection of mobile technology, AI, and product-driven growth, with a strong focus on experimentation and performance.

Would you like to make an impact as part of a company that builds the best mobile apps used by millions of users worldwide? If so, discover your next challenge below.

As a Junior Video Editor you’ll join Labhouse’s video editing team to take concepts that are already proven and expand them into the volume of variations needed to find their best-performing version. Your focus won’t be creating new concepts from scratch, but producing hooks, CTAs, pacing, and format variants of existing ads at scale and A/B testing them to identify what wins.

This is a hands‑on, operational role from day one: you’ll be expected to deliver around 100 iterations a week, working closely with senior editors and Creative Strategists, and building your skills across both classic editing and AI-powered creative tools.

• Produce iterations of existing, proven ads: new hooks, alternate CTAs, pacing changes, and small creative tweaks aimed at keeping performance strong.
• Work at high volume, delivering around 100 iterations a week without losing attention to detail or quality.
• Adapt existing ads into new formats and versions for Tik Tok, Instagram, and Facebook, including localized or platform-specific cuts.
• Apply feedback and direction from Creative Strategists accurately and quickly, iterating until the ad is ready to ship.
• Learn and apply AI-powered creative tools to speed up iteration work, under the guidance of the wider team.
• Keep iteration work organized and on-brief, hitting agreed formats, lengths, and specs across platforms.
• Flag opportunities for further iterations based on what you notice in an ad’s performance or audience response.
• Support the wider video editing team with production capacity during high-volume periods.
