About AI Training Work

AI training (also called data labeling or human feedback work) is the human effort that teaches models how to write, reason, and produce correct code and outputs. Projects commonly involve writing examples, reviewing model answers, and correcting or producing code to form high-quality training data.

This role focuses on programming-related training: you will directly shape how models generate and fix Ruby code, improving their accuracy and usefulness.

The Role

We are hiring experienced Ruby developers for a long-term AI/LLM training project. The engagement runs 6 or more months and offers flexible, remote work.

This is a contractor, part-time opportunity with an hourly rate of $7 USD; expected weekly commitment is between 20 and 40 hours, and applicants should be prepared to commit 25–40 hours per week over the 6-month period.

• Position: Ruby developer focused on AI training and dataset creation.
• Duration: Long-term — 6+ months.
• Hours: Flexible, remote; 20–40 hours/week (ability to commit 25–40 hrs/week expected).
• Pay: $7 per hour (USD).
• Employment type: Contractor, Part-time, Worldwide.

What You'll Do

Work with prompts and model outputs to produce correct, concise Ruby code examples and small programs used as training data.

Debug and correct AI-generated Ruby code so it meets defined standards and can be used to teach models reliable behaviors.

• Write Ruby code snippets and short programs from prompts.
• Review, debug, and optimize AI-generated Ruby solutions.
• Create precise training dataset entries and code examples.
• Ensure code adheres to specified quality and style requirements.

Requirements

Candidates must meet every substantive requirement listed below. You will receive a low Proposal Qualification score if you do not meet the minimum experience requirement.

A Ruby coding assessment will be sent after you submit your proposal; completion is required to proceed.

• Minimum 2 years of professional software development experience with a strong focus on Ruby.
• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
• Proven ability to develop, troubleshoot, and optimize Ruby code.
• Excellent problem-solving skills and attention to detail.
• Effective communication skills in English.
• Ability to work well in a remote team environment.
• Stable internet connection and reliable electricity for consistent remote work.
• Ability to commit 25–40 hours per week for a duration of 6 months.
• Prior experience in AI data labeling or training is preferred but not required.
• Experience level noted: Entry level (role accepts early-career professionals who meet the experience and education requirements).

How It Works

Submit your proposal via OpenTrain; after submission you will be sent a Ruby coding assessment to complete. Successful completion of the assessment is required to move forward.

Work is fully remote and scheduled flexibly within the weekly hours range. Compensation is hourly at $7 USD and you will be engaged as a contractor on a part-time basis.

• Apply through the OpenTrain listing and complete the follow-up Ruby assessment.
• Work remotely from anywhere worldwide; maintain reliable connectivity.
• Contractor arrangement: track hours and invoice according to the engagement terms.

Who Should Apply

Apply if you are a Ruby developer who enjoys writing and debugging code, want to contribute to AI model quality, and can commit to a multi-month remote engagement.

This role suits developers who appreciate flexible hours, clear technical tasks, and the chance to shape how AI systems handle Ruby programming.

• You have 2+ years of professional Ruby experience and relevant degree.
• You can work remotely with dependable internet and electricity.
• You are willing to complete a coding assessment and commit to the stated hours for 6+ months.
