About the Role

Trainers — pre-seeded questions paired with images and their corresponding
"golden" answers — to confirm accuracy, consistency, and adherence to project

This is a task-based, remote-friendly opportunity idóneo for individuals who are
highly meticulous, observant, and skilled at spotting errors or inconsistencies
that others may miss.

question, the image, and the golden answer provided

* Independently verify whether the golden answer is correct based on the image

* Identify and flag incorrect, incomplete, ambiguous, or inconsistent answers

* Provide clear, constructive feedback or corrections to help maintain overall
data quality

* Track recurring error patterns and report them to the project team

* Ensure Trainer output meets the project's quality bar before final sign-off





* Escalate unclear cases (e.g., illegible images, ambiguous questions) to the
project team for resolution

What We're Looking For

* Native/Strong proficiency at Spanish

* Bachelor's degree required

* Excellent attention to detail and a strong quality mindset

* Good visual observation and reading comprehension skills

* Ability to apply guidelines/rubrics consistently and objectively

* Strong written English communication skills, especially for giving feedback

* Prior experience in quality assurance, quality control, editing,
proofreading, data review, data annotation or data labeling is a plus

* Reliable access to a computer and internet connection

Work Format & Compensation
