About MarketFully Group

We’re a content agency helping global brands create and localise search-focused content across languages and markets. We work with in-house marketing teams to deliver content that’s accurate, on-brand, and built to rank.

The opportunity

We're looking for an experienced editor to review and polish SEO content for a B2B client in the testing, inspection, and certification space — technical, compliance-driven content across industries including automotive, medical devices, energy, and industrial safety. You won't be writing from scratch. Your job is to take a writer's draft and get it ready to publish: correct language, consistent tone, properly optimised for search, and true to the brief.

What you'll do

• Edit drafts for grammar, clarity, and tone in European Spanish
• Check content against the SEO brief — keywords used correctly, structure followed, nothing missed
• Flag or fix factual and technical inaccuracies
• Keep a consistent voice across a growing library of content
• Turn work around within agreed deadlines

What we're looking for

• Native-level, European Spanish
• Solid editorial background — publishing, localisation, or content agency experience
• Working understanding of on-page SEO — this isn't a copyediting-only role
• Comfortable with technical or B2B/compliance content

Our hiring process

Quick screening questions on your application. If shortlisted, we'll share rates for this project and confirm you're happy to proceed. A short written SEO assessment (around 30 minutes). Onboarding onto the panel.
