Welo Global is a language and data services company that supplies localisation, translation and training data to technology firms, life sciences companies and enterprises expanding internationally. Its work covers translation and multilingual quality assurance, localisation testing for games and software, data annotation and collection across many languages, and the human evaluation and preference work used to improve large language models. The company recruits linguists, annotators and subject-matter reviewers across dozens of languages, which is why it advertises a very high volume of part-time and contract roles tied to specific language pairs.

ROLE OVERVIEW

We are looking for a Spanish Localization QA Tester / Proofreader to join a long-term.

As a Linguistic Tester, you’ll help bring high-quality Spanish content to life and ensure it feels natural, accurate, and polished for end users. Your main focus will be reviewing and refining localized content, making sure it reads smoothly and is free from errors. This includes checking grammar, spelling, punctuation, consistency, formatting, and cultural or contextual accuracy.

You’ll also work hands-on with products by executing test cases, identifying localization bugs, and reporting issues through internal bug-tracking systems. Once fixes are implemented, you’ll help verify that they’ve been resolved correctly. From time to time, you’ll also have the opportunity to translate content from English into Spanish. In addition, you’ll explore user interfaces to identify localization or functional issues, playing an important role in delivering a seamless and user-friendly experience.

This role is ideal for someone with native-level Spanish fluency, strong attention to detail, and an interest in quality assurance within digital products. If you’re looking for a stable, long-term role (no end date) where you can apply both your language expertise and technical skills, this is a great opportunity.

MAIN DUTIES

- Write and report relevant bugs and errors using best practices through the internal database system.

- Ability to understand and prioritize tasks and issues quickly and efficiently.

- Native language skills in Spanish and and cultural awareness of Spain

- Good oral and written communication.

- Highly organized with attention to detail and a commitment to quality.

- Evaluate translations in the context of software, mobile apps, and documentation.

- Be a subject matter expert for linguistic issues in Spanish (from Spain ); be able to research and resolve linguistic questions.

- Adhere to project-specific quality standards, trademarks, style guides, and client-preferred checklists and glossaries.

- Troubleshoot basic problems; be able to communicate effectively and escalate testing issues.

- Complete assigned tasks in a quality and timely manner.
