Descripción del empleo

Are you looking for an opportunity where you can bring your creative flair for art design, passion for AI generated visual content, and make an impact at an ambitious global business - founded in Spain?
We have an opportunity for an AI Native Content specialist with campaign performance know-how to report directly into the Marketing Director. In this role, you would work from the Barcelona head office of a growing tech company with international customers.

What you'll own

• Social, end to end. Strategy, calendar, creative, publishing, and community across our core channels (primarily LinkedIn, plus other platforms where our audience actually is). You set the direction, you don't wait to be handed a brief.

• Brand and Sales visual assets

• Awareness that compounds. You already know how to make something go viral, and you understand the psychology behind why people stop, screenshot, and share. You build that kind of content consistently, and you can tell the difference between what just fills a calendar and what actually travels.

• AI video production. You don't just "use AI" — You've mastered and love using the current generation of AI video and image tools (Seedance, Higgsfield, and will try whatever lands next), and you're naturally curious enough to teach yourself new models and workflows the moment they appear. You use AI across the whole pipeline — ideation, drafting, image and video, repurposing, iteration — to produce more, faster, and better than a traditional team of three.

• Shoot and edit. You're hands-on with a camera and in the edit, filming, cutting, and finishing short-form video yourself, using AI to speed up and sharpen the process rather than replace the craft.

• Copy that carries. You write the hook, the caption, and the thread yourself — genuinely skilful copy, not AI-generated slop. Our audience is corporate, intelligent, and B2B, not B2C, and the writing has to respect that: sharp, native to the platform, in our voice.

• Out-of-the-box creative. Formats no one else is doing. A distinctive voice. Ideas that feel native to each platform rather than repackaged from a blog post.

• Own the numbers. You read performance data fluently, know which metrics actually matter, and let them steer what you make next, not to chase vanity reach, but to double down on what works.

• Organic growth. Owning organic content and the systems that make it repeatable, and folding in online events content where it drives reach.

What makes you a fit

• You've grown an account from a standing start — your own or a brand's. This is essential, not a bonus: we're not looking to teach someone how to grow an audience, we're hiring someone who can teach us to be better.

• You can show real social proof — a portfolio, or an Instagram/LinkedIn account you've personally run, with the ads and videos to back it up. We want to see accounts and content you actually made and grew, not a list of responsibilities.

• You are genuinely AI-native — AI tools are already your daily practice. You can show us work that only exists because you used them well.

• You can film and edit to a genuinely good standard — comfortable being the one who picks up the camera and cuts the final video, not just briefing someone else.

• You can write — hooks, captions, and copy that sound like a person and fit the platform.

• You have real creative instinct and taste: you can tell good from generic, and you make good even when it's the harder option.

• You understand how social actually works — the mechanics of each platform, why things travel, and what's trending right now (and what's about to be). You spot it early, not after everyone else has.

• You're fluent in campaign numbers: comfortable with analytics, clear on which metrics matter, and able to defend a creative call with reasoning, not just vibes.

• You ship. You'd rather test five ideas this week than perfect one over a month.

• Excellent written English.

Nice to have

• Experience in B2B or tech could be a plus.

• Motion graphics, sound design, or a strong eye for visual polish.

• Clipping skills
