As AI systems become more sophisticated, they rely on human knowledge to better understand context and the world. Vraify partners with leading AI teams to improve how the next generation of intelligent systems learn, reason, and communicate. Your expertise as a Chinese-speaking Python expert will directly support the quality of advanced AI models.
In this hourly, remote contract role, you will review and compare AI-generated Python answers and Chinese-language explanations, evaluating reasoning quality and step-by-step problem-solving for correctness and clarity. You will assess solutions for accuracy, completeness, and adherence to the prompt; identify errors in methodology or conceptual understanding; fact-check technical claims; and provide concise expert feedback. You will also write high-quality reference explanations and model solutions, and rate multiple responses against consistent rubrics.
What you'll do
- Create detailed prompts and high-quality responses across relevant technical topics to guide AI learning.
- Evaluate and rank AI responses to improve accuracy, fluency, reasoning quality, and contextual relevance.
- Test AI outputs for inaccuracies or bias and validate their reliability across use cases.
- Communicate technical review outcomes clearly in English at C1 level or above, including concise issue summaries and rating rationales.
- Review AI-generated Python solutions for correctness, edge-case handling, time and space complexity, and idiomatic Python 3.x usage.
- Create and quality-check Mandarin Chinese prompts, constraints, and acceptance criteria for Python coding and debugging scenarios; Traditional Chinese is preferred.
- Annotate common Python error patterns, including exceptions, off-by-one errors, mutation or aliasing, and encoding issues, using consistent bilingual Chinese and English labels.
What we look for
- 1-5 years of relevant professional experience in Python development, code review, debugging, or technical problem solving.
- Bachelor's degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
- Fluency in Mandarin Chinese and the ability to interpret and evaluate technical content written in Chinese; Traditional Chinese is preferred for Hong Kong.
- English proficiency at CEFR C1 level or above.
- Strong knowledge of Python 3.x fundamentals, including data structures, functions, modules, and exceptions, plus practical debugging skills.
- Ability to evaluate correctness, edge cases, complexity, and readability and apply detailed rubrics consistently across many samples.
- Previous experience with AI data training, annotation, or evaluating AI-generated content is strongly preferred.
- A detail-oriented, self-directed working style suited to remote, flexible-hours contract work.
