OpenTrain AI is the hiring and contracting organization for this role. OpenTrain is the #1 platform for people starting and growing careers in AI training and data labeling—where contributors discover projects, build profiles, and apply quickly.
We focus on practical, remote work that helps shape how modern AI systems behave. This project gives you the chance to contribute directly to real training datasets used to improve AI code generation and reasoning.
About AI Training Work
AI training (also called data labeling or human feedback work) is the human side of building AI: people prepare, check, and improve examples the models learn from. Tasks can include writing examples, reviewing model outputs, debugging generated code, and creating labeled datasets.
These roles are commonly 100% remote and flexible, making them a good fit for experienced engineers who want part-time, contract work while still impacting cutting-edge AI systems.
The Role
You will create C++ training data and validate AI-generated C++ code. Work is remote and flexible within the weekly hour commitment—your output will directly shape how models write and correct C++ code.
This is an ongoing project expected to last about six months with a weekly commitment between 20 and 40 hours. After you apply you'll receive a C++ coding assessment to confirm fit.
Write short C++ code snippets and small programs from given prompts.
Debug, correct, and optimize AI-generated C++ code to meet quality standards.
Create precise, well-documented training examples and expected outputs.
Refine and standardize code so it is clear, efficient, and testable.
Requirements
Applicants must meet the stated educational and experience requirements. You will need reliable remote-working conditions and strong attention to detail for high-quality training data.
If you do not meet the minimum experience requirement described below, your qualification score will be low and you may not be selected for this project.
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++ (applicants with under 2 years will receive a qualification score below 7).
Proven ability to develop, troubleshoot, and optimize C++ code.
Effective English communication skills and ability to work in a remote team.
Stable internet connection and reliable electricity for consistent remote work.
Availability to commit 20–40 hours per week for approximately 6 months.
Compensation & Schedule
This is a contractor, part-time role paid hourly. You set your own schedule within the 20–40 hrs/week commitment to fit your availability.
Exact pay: $6.85 USD per hour. The project is remote and open worldwide; time-zone coordination will be handled through project communications.
Contractor, part-time engagement.
Hourly rate: $6.85 USD per hour.
Flexible hours; 20–40 hours per week expected.
Project length: about 6 months (ongoing project).
How to Apply
Submit your proposal through the OpenTrain application flow. After submission you will be sent a C++ coding assessment; completion of that assessment is required for consideration.
When applying, highlight relevant C++ projects or work experience and confirm your weekly availability and remote setup.
Submit a proposal with your C++ experience and availability.
Complete the provided C++ coding assessment after submission.
If selected, begin the contractor onboarding process and start contributing to dataset creation and code validation.
