Experienced Japanese Language AI Data Reviewer – Remote Evaluation Specialist for Advanced Language Model Quality Assurance
About brighthush and the AI Language Landscape
brighthush is at the forefront of artificial intelligence, building next‑generation conversational agents that understand and generate natural language with unprecedented nuance. Our mission is to create AI that is not only intelligent but also safe, reliable, and culturally aware. As the world’s conversations shift into multilingual contexts, we need experts who can scrutinize the subtle differences between human‑like responses and machine‑generated text. That’s where you come in.
Why This Role Matters
In the rapidly evolving field of AI, the quality of training data directly influences the performance and safety of language models. As a Japanese Language AI Data Reviewer, you will be the gatekeeper that transforms raw model outputs into actionable, auditable labels. Your work will shape the next generation of AI systems, ensuring they respect cultural nuances, comply with safety standards, and deliver consistent, high‑quality responses to users worldwide.
Key Responsibilities
- Rubric‑Based Evaluation: Assess Japanese generalist model outputs against a versioned, detailed rubric, assigning severity tags and identifying edge cases.
- Paired Response Comparison: Review paired responses to the same prompt, determine the superior answer, and provide a clear, structured rationale.
- Hallucination & Safety Tagging: Detect hallucinations, instruction‑following failures, and unsafe content, applying the correct policy category and severity level.
- Ambiguity Capture: Identify ambiguous or poorly constructed prompts, flag them, and route them back to the program team for rubric refinement.
- Calibration & Quality Assurance: Maintain reviewer‑quality scores by calibrating against gold‑standard examples each week, ensuring consistency across batches.
- Failure Mode Documentation: Record recurring failure patterns, providing actionable insights for the modeling team to target in future training cycles.
- Continuous Improvement: Propose rubric clarifications and enhancements based on observed trends and edge cases.
Essential Qualifications
- Prior experience in evaluation, annotation, or human‑rater roles focused on Japanese language content or related AI evaluation tasks.
- Proficiency in applying multi‑page rubrics consistently across large batches of data.
- Strong written communication skills: the ability to articulate issues clearly, referencing specific rubric clauses.
- Exceptional attention to detail, with a keen eye for spotting subtle errors and prompt‑level problems.
- Reliable asynchronous availability of at least 10 hours per week, with the flexibility to adjust hours as project needs evolve.
Preferred Background (Nice to Have)
- Academic or professional background in linguistics, content moderation, or trust & safety review.
- Experience with inter‑rater agreement metrics, calibration cycles, and statistical quality control.
- Domain expertise that enables you to spot subject‑matter inaccuracies that automated checks may miss.
