About AI Training Work

AI models improve through carefully reviewed examples and human feedback. In this role, your Ruby and Rails expertise will help evaluate whether AI-generated code is correct, logical, maintainable, and clearly explained, directly shaping how coding models perform.

• Work at the intersection of software engineering and artificial intelligence
• Use professional programming judgment to evaluate model outputs
• Contribute to the development of more accurate and useful coding systems

The Role

You will review and compare AI-generated Ruby and Ruby on Rails solutions, evaluate the quality of their reasoning, and provide detailed technical feedback. The work includes identifying issues in MVC structure, domain modeling, control flow, readability, and maintainability.

You will also fact-check technical content and write idiomatic Ruby examples and model answers that demonstrate strong engineering practices. Reviews should assess correctness, clarity, testability, and long-term code quality.

• Intermediate experience level
• Ruby code review and AI data training focus
• English-language technical communication
• Eligible locations include Bangladesh, Bhutan, Brazil, Cambodia, Germany, India, Indonesia, Malaysia, Nepal, Pakistan, Singapore, Sri Lanka, Thailand, the Philippines, the United States, Timor-Leste, and Vietnam

What You’ll Do

Your evaluations will help distinguish strong AI-generated solutions from responses that are incomplete, misleading, or difficult to maintain. You will explain the reasoning behind your judgments and produce high-quality examples that can guide better model behavior.

• Review and compare AI-generated Ruby and Rails solutions for correctness and reasoning quality
• Identify issues in MVC structure, domain modeling, control flow, readability, and maintainability
• Fact-check technical content and explain why a solution is strong or weak
• Write idiomatic Ruby examples and high-quality model answers
• Evaluate responses for clarity, testability, and long-term code quality

Required Qualifications

This role requires professional Ruby programming experience in production environments and hands-on experience building or maintaining Ruby or Rails applications. You should be comfortable judging both technical correctness and the quality of explanations in English.

A bachelor’s degree in Computer Science or a closely related technical field is preferred. Prior AI data training, large-scale code review, or evaluation of AI-generated technical content is strongly preferred.

• Strong Ruby and Ruby on Rails production experience
• Strong understanding of Rails, MVC architecture, and idiomatic Ruby patterns
• Ability to review Rails controllers, models, and service-layer design
• Ability to evaluate readability, maintainability, and logical correctness
• Excellent English writing skills for clear technical explanations
• Experience using LLMs or AI coding assistants while programming
• Prior AI data training, code review, or technical evaluation experience is preferred

Helpful Background

The following experience can help you succeed in the role, particularly when evaluating varied codebases and advanced model outputs.

• Ruby on Rails, Sinatra, and RSpec experience in real projects
• Merged pull requests in Ruby open-source projects
• Experience with metaprogramming or test-heavy systems
• Competitive programming exposure
• Familiarity with common failure modes in LLM and coding-assistant output
