Cellexia Ltd

Cellexia Labs currently serves customers in markets all over the world, with our fastest-growing communities in Europe, the US, Canada, and Australia. We're a fully remote, international team, small by design, where everyone owns something real and decisions are made by the people closest to the work.

In skincare, the ad is where the relationship starts. A stranger scrolling past on a phone gives us a second or two, and in that time the ad has to earn a look, a click, and the start of trust. Done well, it brings in customers who stay and reorder. Done badly, it burns budget on people who were never going to buy.

This role runs that moment. You'll own our Meta advertising: what we test, what we scale, where the budget goes, and how we know it's working. It's work where decisions turn into numbers within days, and every number tells you something.

For a sharp, driven media buyer who wants their work judged by results, this is a rare opportunity: ownership of a growing brand's biggest growth channel.

A few examples of your responsibilities

Own the Meta ad account. Plan, launch, and manage campaigns across our markets. You'll decide the structure, the audiences, the budgets, and when to scale or cut.

Build a testing engine. Run a steady stream of tests on creative, hooks, angles, audiences, and offers. Know what you're testing, why, and what you'll do with the result.

Scale what works. Find the winners, push spend up without breaking performance, and keep acquisition profitable as budgets grow.

Work hand in hand with the creative team. Turn what the data shows into clear briefs for our writers and video editors, so the next round of ads is sharper than the last.

Make the numbers trustworthy. Keep tracking and attribution clean, so every decision rests on data you can believe. Report on cost per acquisition, return on ad spend, and customer quality.

Take every market seriously. Adapt campaigns to the tastes, budgets, and buying habits of customers in Europe, the US, Canada, Australia, and beyond.

Keep the account healthy. Know Meta's ad policies, especially for skincare claims, and keep our campaigns compliant and our account in good standing.

Move fast without cutting corners. Use AI tools to speed up analysis, research, and reporting, then apply your own judgment to make the final calls.

What we look for

Analytical mind. You read the numbers and know what they mean. You can tell a real signal from noise, and explain why a campaign is working or not.

Hands-on skill. You've managed Meta ad accounts with real budgets and understand how structure, creative, and audience work together.

Creative instinct. You can tell a strong ad from a weak one before the data does, and you can explain why in words a writer or editor can use.

Ownership. You treat every campaign as yours until it performs. You hold yourself to a bar that keeps rising.

Calm under pressure. You stay steady when performance dips, find the cause, and act without panicking or hiding the problem.

Team spirit. You support the best idea, not your own. You take feedback well and give it generously.

Relevant experience. [2+] years running Meta ads for e-commerce or consumer brands, with results you can show, ideally with the numbers to prove it. Experience in beauty, skincare, or another consumer category is a strong advantage. Excellent written English is essential.

The selection process

We care about what you can do, not how polished your CV looks. That's why our process is built around how you think and work, not just where you've worked.

Step 1: Apply. Submit your application and CV through this link: https://jobs.cellexialabs.com/?job=mediabuyer_jazz

Step 2: Online assessments. Right after you apply, you'll take two short tests: a problem-solving test and a personality test. The problem-solving test shows us how you reason through unfamiliar challenges. The personality test helps us understand how you work and whether the way we operate will suit you.

Step 3: Interview. If your results stand out, we'll invite you to interview with the team.

We move quickly. The whole process, from application to interview invitation, takes a couple of days.

If you like the role and believe you could excel at it, don't talk yourself out of applying. A less conventional background is welcome here if your results speak for themselves.

Before you apply

Cellexia Labs is a demanding environment. We hold ourselves to a high bar, and we ask the same of the people who join us. In return, you get real freedom, work that goes live, and a front-row seat to the growth of a brand.

If this sounds like the work you want to be doing, we'd love to hear from you.
