About AI Code Evaluation
AI training is the human side of building artificial intelligence. Experts review model-generated content, identify subtle errors, write strong reference examples, and explain why one answer is better than another.
As a C++ AI Code Review Engineer, you will apply advanced software engineering and systems programming judgment to help evaluate technical AI outputs. This is remote, flexible contractor work in a fast-growing field where specialists directly influence how AI systems perform.
The Role
OpenTrain AI is hiring an expert C++ AI Code Review Engineer to support AI training work focused on C++ code review and evaluation. You will review AI-generated C++ code, systems designs, and technical explanations, then produce reference implementations and step-by-step reasoning for complex engineering problems.
You will assess solutions for accuracy, clarity, safety, prompt adherence, logic, memory handling, concurrency, and performance. You will also fact-check technical details and compare multiple model responses for correctness and reasoning quality.
- Expert-level contractor role focused on C++ code review and AI output evaluation
- Remote, part-time work requiring 20 or more hours per week
- Hourly pay of $40-$65, with estimated project earnings of $6,400-$10,400 based on the schedule and duration shown on OpenTrain
- Future project opportunities may be available
What You'll Do
You will work from project guidelines and source materials to produce consistent, technically rigorous evaluations. Strong performance requires careful attention to subtle implementation issues and the ability to communicate complex reasoning clearly in English.
- Review source materials and model outputs against project guidelines
- Write expert responses and explain your reasoning clearly
- Identify errors in logic, memory handling, concurrency, safety, and performance
- Produce high-quality explanations and model solutions that demonstrate correct methods
- Rank and compare multiple AI responses based on correctness and reasoning quality
- Maintain consistency and quality across repeated review tasks
Required Expertise
This position requires advanced modern C++ expertise and substantial practical, academic, or professional experience with detailed code review and evaluation. You should be comfortable analyzing production-quality systems code and explaining both the problem and the correct approach.
Prior experience evaluating AI-generated technical content or training data is a strong plus, but the core requirement is deep C++ and systems programming knowledge paired with disciplined written reasoning.
- Relevant professional, academic, or practical expertise in C++ code review and evaluation
- Deep knowledge of modern C++ from C++11 onward, including templates, move semantics, smart pointers, and the STL
- Strong systems programming background in concurrency, operating systems, low-level performance optimization, and memory management
- Hands-on experience with C++ build systems, compilers, linkers, debuggers, and profiling tools
- Proven experience reviewing C++ for safety, performance, maintainability, and lifetime correctness
- Comfort working with version control, CI/CD workflows, and automated testing frameworks
- Fluency in English, clear technical writing, and the ability to reason step by step
- Highly detail-oriented and systematic, with strong subtle issue detection skills
Who Should Apply
This role is suited to experienced C++ engineers, systems programmers, technical reviewers, and other specialists who can evaluate implementation quality beyond whether code simply compiles. Apply if you enjoy analyzing complex engineering decisions and turning your conclusions into precise explanations.
The opportunity is available remotely to contractors in Bangladesh, Bhutan, Brazil, Cambodia, Germany, India, Indonesia, Malaysia, Nepal, Pakistan, Singapore, Sri Lanka, Thailand, the Philippines, the United States, Timor-Leste, and Vietnam.
- Expert experience level
- English language fluency required
- 20+ hours per week
- Remote contractor availability in the listed countries
- Prior AI-generated technical content evaluation experience is advantageous
