About AI training and why it matters

AI training (data labeling/annotation/human feedback) is the human work that teaches models how to understand code, language, images, and more. Contributors do flexible, remote work that directly improves model quality used in research, developer tools, education, and production systems.

The role

We are hiring Subject Matter Experts (SMEs) in one precisely chosen software or computer science category to review, categorize, and annotate technical content. This contractor, part-time role pays $40 per hour and expects roughly 20+ hours per week; exact weekly commitment will be confirmed during the interview.

Work is remote but restricted to candidates located in the United States and fluent at a native English level. You may only apply for one category and must have 5+ years of experience in that category.

• Labeling focus: computer code and programming content (COMPUTER_CODE_PROGRAMMING).
• Label types you’ll perform: code annotation, evaluation/rating, and writing/rating prompt responses (SFT).
• Employment: Contractor, Part-time. Hourly pay: USD 40/hour.
• Time: Target ~20+ hours/week; interviewer will confirm exact hours you can commit.

What you'll do

As a Labeler you will ensure dataset quality for learning models, developer tools, and educational materials by applying your domain expertise to real technical content.

• Review and categorize code snippets, scripts, and technical explanations for correctness and intent.
• Annotate examples with labels, metadata, and explanatory notes that improve model learning.
• Evaluate and rate model-generated responses for accuracy, safety, and usefulness.
• Write or refine prompt-response examples where requested (supervised fine-tuning style tasks).
• Follow project guidelines precisely and document edge cases and ambiguities for reviewers.
