? 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 growing our freelance panel for a long-term client engagement: a B2B company providing testing, inspection, and certification services across industries including automotive, medical devices, energy, and industrial safety. You'll write and optimise search-focused content for the Spanish market — service pages, certification and compliance explainers, and occasional blog content.

Roughly half the work is refreshing and optimising existing pages rather than writing from scratch, so you'll need to be just as comfortable editing within an established voice as writing something new.

✍️ What you'll do

Write new service and landing pages from a brief

Optimise existing content for target keywords, structure, and freshness

Localise existing content into Spanish — adapting tone and terminology for the local market, not just translating

Occasionally write longer-form blog or article content





Work from keyword briefs and a shared style guide

? What we're looking for

Native-level European Spanish, with strong knowledge of the Spanish market

Proven SEO copywriting experience — you understand keyword placement, search intent, and on-page structure, not just good writing

Comfortable with technical or B2B content; experience with compliance, certification, engineering, or industrial topics is a strong plus

Reliable turnaround on agreed deadlines

? 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

? How to apply

Send your CV and, if you have them, a couple of examples of SEO or technical content you've written.
