About OpenTrain

OpenTrain is the #1 platform for finding and building careers in AI training and data labeling. We help freelancers discover projects, consolidate proof of work in one profile, and grow a durable freelance career working directly on the human side of AI.

OpenTrain AI is hiring for this role. You will contribute directly to how language-aware AI systems understand and generate Welsh by applying your language expertise to real labeling and review tasks.

About AI training and this work

AI training (also called data labeling or annotation) is the human work that teaches models how to use language correctly. Your reviews, translations, and ratings help AI systems learn accurate spelling, tone, cultural relevance, and natural phrasing in Welsh.

Many projects are fully remote and flexible, making this work a great fit for people who want part-time, skill-building roles that directly influence cutting-edge language technology.

The role

We are looking for a Welsh Language Review Specialist to review, translate, proofread, and QA Welsh-language text used in AI training. You will work as a remote part-time contractor for OpenTrain AI on text-based tasks that include translation/localization and evaluation/rating.

This role is best for someone with real-world experience working with Welsh language content who can reliably deliver clear, consistent feedback and maintain quality across repeated labeling tasks.

What you'll do

You will perform hands-on language tasks to improve model outputs and dataset quality. Tasks are text-focused and may include direct translation, linguistic edits, and rating or annotating language quality.

  • Review Welsh content for accuracy, tone, style, spelling, and cultural relevance.
  • Translate written materials between English and Welsh with attention to idiom and register.
  • Provide clear, constructive feedback and justification for edits and ratings.
  • Perform quality assurance checks to ensure consistent output across similar items.
  • Contribute to style guidance and examples to help standardize future reviews.

Requirements

You must meet the language and experience qualifications below. We will not invent qualifications beyond what is listed here.

  • Native or near-native fluency in Welsh (written and spoken).
  • Fluency in English sufficient to translate and provide written feedback.
  • Experience in translation, localization, editing, or content review for Welsh.
  • Strong understanding of Welsh idioms, norms, regional variation, and cultural references.
  • Excellent written communication, attention to detail, and ability to work independently.
  • Reliable remote work habits, good time management, and comfort collaborating with a distributed team.

Schedule, employment type, and pay

This is part-time contract work with an expected minimum of 20+ hours per week. Tasks are remote and typically completed on a flexible schedule.

OpenTrain AI does not list a fixed hourly rate in this posting; pay details will be shared during hiring or when specific projects are offered.

  • Employment type: Contractor, Part-time.
  • Time requirement: 20+ hours/week (remote, flexible).
  • Data type: Text; label types: Translation/Localization and Evaluation/Rating.

Who should apply and how it works

Create or sign in to your OpenTrain profile, complete any sample tasks if requested, and submit your application. OpenTrain matches you to projects and tracks your proof of work so you can grow your freelance AI-training career over time.
