About AI Training Work

AI training is the human side of building artificial intelligence. Contributors create, review, and evaluate examples that help AI models understand language, follow instructions, generate useful content, and produce accurate technical outputs.

This project focuses on written and structured data rather than visual tagging. Your software knowledge and language expertise will help shape training and evaluation materials for AI models.

• Work with prompts, generated responses, and structured examples.
• Apply technical judgment to software development and engineering contexts.
• Contribute to a fast-growing field with flexible, part-time project opportunities.

The Role

As a Software Developer and AI Trainer, you will create and edit structured data formats, including JSON files, tables, and lists, in a native language. You will design prompts, generate content, and verify that each data item is accurate, relevant, precise, and aligned with software development and engineering contexts.

The role is intermediate level and pays $25 per hour. It is offered as part-time contractor work, with a listed expectation of 20 or more hours per week and a minimum commitment of 15 hours per week.

• Payment type: Hourly, $25 USD per hour.
• Engagement: Part-time contractor.
• Workload: 20 or more hours per week listed; 15 hours per week minimum commitment.
• Data type: Text.
• Primary work: Structured data generation, JSON, tables, lists, and text generation.

What You’ll Do

You will produce high-quality written examples that help train and evaluate AI models. The work requires careful handling of technical content, structured formats, and native-language expression.

You may also create and manipulate JSON prompts for AI model training, assess the relevance of generated content, and refine outputs so they meet project requirements.

• Design prompts for software development and engineering scenarios.
• Generate and edit JSON files, tables, and lists.
• Create accurate, well-structured text in your native language.
• Review data for precision, relevance, consistency, and quality.
• Use programming knowledge to work with Python, JavaScript, SQL, and HTML/CSS content.
• Apply problem-solving and critical-thinking skills to ambiguous or technical examples.

Requirements

You must be a native speaker of one qualifying language and have English proficiency at a minimum B2 level. The project requires strong native-language writing ability, ideally supported by at least two years of creative or technical writing experience.

You must also have a strong software development or software engineering background, demonstrated by at least two years of software development experience or four years of formal software development education.

• Native speaker of one qualifying language: Korean, Japanese, German, Italian, Spanish, Chinese, Portuguese, or French.
• Spanish candidates must be native speakers from Spain or Mexico.
• Chinese candidates must be native speakers of Simplified Chinese, Hong Kong Chinese, or Taiwan Chinese.
• English proficiency at B2 level or higher.
• Experience with JSON, tables, lists, and other structured data formats.
• Proficiency in Python, JavaScript, SQL, and HTML/CSS.
• Strong attention to detail and commitment to precise, high-quality data.
• Ability to create and manipulate JSON prompts for AI model training.
• Availability to start on August 19 as specified in the project listing.
• Ability to commit at least 15 hours per week.

Preferred Experience

Previous experience with written LLM data training or data-labeling work is a plus, particularly experience involving writing tasks rather than visual data tagging. Relevant work may include creating prompts, writing model responses, or evaluating generated text.

Candidates should be comfortable writing clearly and naturally in their native language while applying software development knowledge to technical examples.

• Two or more years of creative or technical writing experience is preferred.
• Previous written AI-training or data-labeling experience is helpful.
• Experience with prompt writing, response generation, or text evaluation is relevant.
• Visual-only tagging experience does not replace the required writing experience.

Who Should Apply

This opportunity is suited to developers, software engineers, technical writers, and multilingual technology professionals who can combine programming knowledge with excellent native-language writing. It may also fit candidates who have contributed to written AI-training projects and understand how to create consistent, useful examples for language models.

Eligible locations listed for the project include France, Germany, Hong Kong, Italy, Japan, Mexico, South Korea, Spain, and Taiwan. The project is not listed as worldwide.

• Software developers with strong structured-data skills.
• Bilingual or multilingual technical professionals who write naturally in a qualifying native language.
• Candidates who enjoy detailed, accuracy-focused writing and review.
• Applicants able to meet the stated weekly commitment and project start timing.
