About AI Training Work (C-focused)

AI training is the human process that teaches models how to write, understand, and fix code by providing high-quality examples and corrections. In coding projects, contributors create target programs, rate or fix AI outputs, and assemble datasets that models learn from.

This project focuses on C code: generating concise examples, debugging AI-generated snippets, and producing clear, reproducible training data that helps models produce correct, optimized C programs.

The Role

We are hiring C developers to contribute to a long-term AI training project. You'll generate C code snippets and short programs from prompts, debug and improve AI-generated C, and produce precise labeled examples used to train models.

This is a remote, contract, part-time role for 6 or more months with a flexible schedule. Expected weekly commitment is 20–40 hours. Pay is hourly at USD 8.85 per hour. After you submit your proposal, you will receive a C coding assessment to complete as part of the evaluation.

• Duration: 6+ months
• Time commitment: 20–40 hours per week (flexible schedule)
• Employment type: Contractor, Part-time
• Pay: USD 8.85 per hour (pay-per-hour)

What You'll Do

Day-to-day tasks center on producing high-quality C examples and corrections that become training data for AI systems.

• Write C code snippets and short programs to match specific prompts and requirements.
• Review and debug AI-generated C code, correcting logic, syntax, memory management, and edge cases.
• Optimize and refactor small programs to meet target constraints (clarity, performance, correctness).
• Annotate and document examples so they are reproducible and unambiguous for model learning.
• Follow labeling guidelines and quality standards to ensure datasets are consistent and reliable.

Requirements

Candidates must meet the stated educational, experience, and logistics requirements to be considered.

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
• At least 2 years of professional software development experience with a strong focus on C.
• Proven ability to develop, troubleshoot, and optimize C code.
• Excellent problem-solving skills and strong attention to detail.
• Effective communication skills in English to collaborate with a remote team.
• Stable internet connection and reliable electricity to ensure consistent remote work.
• Ability to commit 20–40 hours per week for a duration of at least 6 months.
• Prior experience in AI data labeling or training is preferred but not required.
• Experience level listed for this role: Entry level (per job posting data).

How the Hiring Process Works

To apply, submit your proposal through the OpenTrain listing. After submission you will receive a C coding assessment to complete; successful completion is required for further consideration.

We will review proposals and assessment results, then contact selected candidates with next steps and onboarding details.

• Submit proposal via OpenTrain
• Complete the emailed C coding assessment
• Assessment and application reviewed; selected applicants contacted

Who Should Apply

This role is a fit for developers who are comfortable writing and debugging C and who want to contribute directly to datasets that teach AI systems to code. It suits people who need remote, flexible part-time work and can reliably commit 20–40 hours weekly for an extended project.

• C developers with 2+ years’ experience and a relevant degree.
• Remote-friendly contributors who have stable internet and power.
• People who enjoy clear technical tasks: writing examples, fixing bugs, and documenting solutions.
