Specialist, Content Optimization

Brainlabs is the media agency built to answer one question: what's actually driving profit? Founded in 2012 by Daniel Gilbert, we were built by engineers before we were a media agency. Today, 1,000+ Brainlabbers across five continents use our proprietary agents, built on 32 media tools and over 2,500 logged experiments, to help brands connect every channel they plan and buy to one thing: the bottom line.

The role

Brands live and die by their product pages. A great product with poor content gets buried. A well‑optimized listing with clear titles, strong keywords, and accurate attributes climbs. This role owns that gap.

As a Content Optimization and Catalogue Management Specialist, you’ll be responsible for how our clients' products show up, get found, and convert on Amazon and Mercado Libre. That means writing and refining listings, managing catalogue health, and building the kind of organic visibility that doesn't disappear the moment ad spend drops.

You’ll work directly with client teams and internal strategists to keep catalogues clean, content sharp, and rankings moving in the right direction.

What will you do?

Your day‑to‑day breaks into two connected areas.

Content Optimization

Content optimization is where you drive organic performance. You’ll conduct keyword research, write and update product titles, bullet points, descriptions, and backend attributes. You’ll audit existing content against platform best practices and identify gaps before they become ranking problems. You’ll test copy variations and track what actually moves the needle.

Catalogue Management

Catalogue management is where you keep the operation running. You’ll handle the publication and maintenance of product listings, manage bulk uploads and flat files, resolve listing errors and suppressed ASINs or items, and keep content synchronized across multiple accounts and categories. When something breaks, you figure out why and fix it. Beyond those two pillars, you’ll monitor organic ranking performance, report on content health metrics, and bring recommendations that are grounded in data, not guesswork.

What are we looking for?

Experience

Around three years working in content optimization and/or catalogue management on Amazon and/or Mercado Libre. You understand how these platforms rank organic results and you’ve influenced those rankings for real brands.

Platform Fluency

You know Seller Central and Vendor Central. You’ve worked with Mercado Libre item publication flows. Flat files, bulk uploads, listing errors, and suppressed items are familiar territory, not new concepts.

Keyword and SEO Fundamentals

You know how to research, prioritize, and place keywords in a way that platforms reward. You understand the difference between what drives impressions and what drives conversions.

Analytical Mindset

You read performance data and draw conclusions from it. If organic rankings drop, you have a process for diagnosing why. If a content change works, you can explain what it did and why it helped.

Attention to Detail

Catalogue work is unforgiving. A wrong attribute, a missing image, a misformatted file: these things cause real problems. You catch errors before they ship.

English Proficiency

You’re comfortable reading, writing, and communicating professionally in English. You’ll work with international teams and documentation.

Nice to Have

• Experience with tools like Helium 10, Data Dive, or Jungle Scout.
• Familiarity with Amazon's A+ Content and Brand Store modules.
• Experience across multiple categories or markets.
