About OpenTrain

OpenTrain is the #1 platform for people starting and growing careers in AI training and data labeling. We connect contributors to live projects that shape how next-generation AI behaves and give you a clear path to build skills, reputation, and earnings in this fast-growing industry.

Many AI training roles are highly flexible and remote, and they let contributors work part time around other commitments. This posting is for a project run by OpenTrain AI; please note this particular role requires you to be based in France and fluent in French.

About AI training and this work

AI training (also called data labeling or annotation) is the human work behind how AI systems learn: people prepare, review, and improve examples the models train on. Tasks range from transcribing audio and labeling images to writing and editing code-related data and creating question-and-answer pairs.

This role focuses on web development artifacts—an important and growing area of AI training where precise, well-structured examples directly improve model understanding of web content and code quality.

The Role

You will work as a Frontend Developer on an ongoing AI training project that requires analyzing website screenshots and web code, producing detailed annotations and Q&A pairs, and making targeted HTML/CSS/JavaScript edits to meet project specifications.

This is a contract, part-time role. Candidates must be native French speakers located in France, able to start on August 12, and ready to complete a short coding skills test as part of the screening process.

• Hourly pay: USD $20.50 per hour (PAY_PER_HOUR)
• Start date: Must be available to start on August 12
• Commitment: Minimum 15 hours per week (preference for candidates who can commit 25+ hours)

What You'll Do

Your day-to-day work will involve close reading of website screenshots and snippets, annotating web elements, creating clear question-and-answer pairs that capture intent and edge cases, and editing or suggesting improvements to HTML/CSS/JS so examples meet quality standards.

Accuracy, consistency, and clear explanations are essential. You will follow project guidelines to mark up components, note accessibility or layout issues, and propose code fixes that a downstream model or reviewer can understand and apply.

• Create detailed annotations and labels for web UI elements and layout behaviors
• Write Q&A pairs that describe element function, expected behavior, or bugs
• Edit and improve HTML, CSS, and JavaScript snippets to meet spec
• Document changes and reasoning so other contributors and reviewers can follow

Requirements

Applicants must meet all of the following hard requirements; we will verify these during screening and via a coding test.

This project emphasizes precision and technical skill—please read the requirements carefully before applying.

• Native French speaker based in France (must be fluent and resident in France)
• At least 2 years professional experience with each of HTML, CSS, and JavaScript
• Able to commit a minimum of 15 hours per week; preference for candidates available 25+ hours
• Available to start on August 12 and complete a coding skills test
• Strong attention to detail, analytical problem-solving, and ability to follow annotation guidelines
• Basic understanding of web design and page structure; ability to diagnose and fix common layout and interaction issues

Nice-to-have

The following are not required but will make your application more competitive.

• Previous experience contributing to AI training or data-labeling projects
• Familiarity with writing clear, concise documentation and examples for reviewers
• Comfort annotating screenshots and translating visual issues into code fixes

How to Apply and Next Steps

When you apply, make sure your profile lists your years of experience in HTML, CSS, and JavaScript and confirms you are based in France and a native French speaker.

Applications will be reviewed quickly for immediate start. Qualified candidates will be asked to complete a short coding test and a sample annotation task before final selection.
