• Multilingual Prompt Design & Optimization: Create detailed prompts in Japanese and/or English with multiple constraints and instructions, ensuring natural phrasing and real‑world relevance for Japanese‑speaking users.
• Define and Document Evaluation Standards: Establish high‑level expectations for correct responses in Japanese consumer contexts, and develop comprehensive rubrics that account for linguistic nuance, tone, and cultural conventions.
• Model Testing and Grading (Bilingual): Run prompts through models and assess preliminary outputs for accuracy, fluency, and cultural fit in Japanese, comparing results against English when needed.
• Benchmarking & Quality Assurance: Collaborate in QA review processes to ensure prompt tasks and rubrics meet rigor—maintaining consistency and reliability across Japanese‑language benchmarks before integration into official evaluations.

• Strong writing and critical thinking skills.
• Ability to work independently and meet deadlines.
