About AI Training Work

AI training is the human side of building artificial intelligence. People with real-world expertise review examples, evaluate model responses, and provide clear feedback so AI systems can become more accurate, useful, and reliable.

In this project, your technical judgments about AI-generated Swift code will help improve how models write, debug, and explain iOS software.

• Remote work using a computer and an internet connection
• Flexible part-time scheduling around your availability
• Direct involvement in cutting-edge coding and model-evaluation work

The Role

OpenTrain AI is seeking a Swift LLM Code Review Engineer for AI training work focused on Swift iOS code review. You will assess AI-generated Swift and iOS code using project guidelines and rubrics, then provide evidence-based feedback that can improve model behavior.

This is a part-time remote contractor engagement estimated at about 20 hours per week for 1–3 months. The role is listed as entry level, while the project requires at least two years of hands-on Swift/iOS development experience.

• $55 per hour
• Estimated project earnings of $8,800 based on the listed schedule and duration
• Flexible schedule
• Contractor and part-time engagement

What You’ll Do

You will review source materials and model outputs against detailed project instructions. Your written assessments should explain the reasoning behind each judgment and remain consistent across repeated review tasks.

• Evaluate AI-generated Swift and iOS code
• Assess correctness, maintainability, performance, and UI logic quality
• Apply project rubrics consistently
• Document evidence-based judgments
• Explain technical decisions clearly in written feedback
• Review model outputs against project guidelines
• Help improve AI behavior through careful code evaluation
• Maintain quality and consistency across review tasks

Requirements

The most important qualification is strong, practical knowledge of Swift iOS code review. Prior AI training experience is not required unless stated elsewhere in the project requirements, but you should be comfortable evaluating coding outputs from large language models and communicating complex technical concepts clearly.

• At least 2 years of hands-on Swift/iOS development experience
• Relevant professional or academic expertise in Swift iOS code review
• Significant experience using LLMs for coding, debugging, and code review
• Strong understanding of Swift fundamentals, memory management, and ARC
• Ability to evaluate correctness, maintainability, performance, and UI logic
