About AI training work

AI training (data labeling and human feedback) is the human side of building intelligent systems: people prepare, review, and rate examples that models learn from. Work can be fully remote, flexible, and accessible—making it a strong option for part-time and freelance contributors.

This role focuses on evaluating generated model responses and trainer/QAs for quality, fluency, and rubric alignment, helping shape how Czech-language AI systems respond and perform.

The role

As the Czech Quality Assurance Lead you will review Czech AI-generated content and trainer or QA submissions for quality, consistency, and alignment with project rubrics. You will provide precise written feedback, track recurring issues, maintain Czech project documentation, and support onboarding and training for remote contributors.

• Location: Czech Republic only
• Time: 20+ hours per week
• Pay: $30 per hour

What you'll do

Daily work centers on reviewing Czech-language text for fluency, grammar, spelling, tone, cultural fit, meaning preservation, instruction-following, and proper formatting. You will use rubrics to rate submissions, offer corrective feedback, and help enforce consistent language standards across contributors.

• Review AI-generated Czech text and trainer/QA work against guidelines and rubrics
• Write clear feedback on accuracy, fluency, grammar, diacritics, punctuation, tone, and cultural appropriateness
• Track recurring quality issues and suggest workflow improvements for Czech projects

• Native or near-native Czech reading and writing ability
• Strong English communication skills for project guidelines and written feedback
• Experience in Czech writing, editing, translation, localization, content QA, AI training, or similar language-review work
• Deep knowledge of Czech grammar, spelling conventions, punctuation, diacritics, declension, gender agreement, tone, register, and cultural context
• Ability to evaluate content against detailed rubrics and spot mistranslation, literal phrasing, awkward wording, missing diacritics, hallucinated claims, or inconsistent terminology
• Comfort using remote collaboration tools and working in fast-moving quality workflows

Helpful background

These are not strict requirements but will help you hit the ground running and lead small remote teams more effectively.

• Degree in Czech, linguistics, translation, communications, journalism, education, QA, or related field
