AI Trainer (SWE), Part-Time Software Task Evaluation - Remote (52 countries)

• $60–$120 per hour equivalent, paid per accepted task

• 100% remote

• Part-time independent contractor

• Under 20 hours a week, you choose when

Use expert software-engineering judgment to create realistic coding problems and review AI-generated implementations for correctness, robustness, testing, and reproducibility.

OpenTrain AI is hiring for this role.

AI training work turns real engineering examples and expert feedback into better model behavior. You will define tasks, tests, reference solutions, and evaluation standards, then assess technical submissions with clear reasoning.

What you'll do

• Create demanding software-engineering tasks for AI model evaluation

• Turn requirements into clear prompts and measurable tests for a correct result.

• Set up repeatable workspaces, supply answer keys and checks, and define how quality is judged.

• Examine model code and technical work for sound behavior, resilience, coverage, and repeatable results.

Why this is worth your time

• Apply expert software-engineering judgment to structured AI evaluation tasks.

• Turn design, debugging, and testing experience into objective technical standards.

• Explain defects, trade-offs, and useful corrections in clear written feedback.

• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• Bring expert software-engineering skill and paid history improving or assessing AI systems.

• Use Python well plus professional experience in another language (for example, Go, C#, Rust, TypeScript, JavaScript, Java, or C++).

• Working knowledge of software design, debugging, testing, version control, and dependency management.

• Point to substantial public work such as repositories, open-source projects, developer tools, systems, papers, benchmarks, or engineering notes.

• Professional fluency in English.

• Helpful background includes model-task design, answer keys, testing, grading, benchmark work, code-submission review, agentic coding evaluation, Linux, Docker, CI/CD, command-line work, sandboxes, or competitions.

• Have prior paid experience training, evaluating, benchmarking, or improving AI systems.
