About The Role
Join the Human‑Centered AI – Human Evaluation team at a leading

  • Perform QA across diverse media assets: review, verify, edit, score, transcribe, copywrite, and report
  • Produce detailed reports on issues and patterns; translate findings into actionable recommendations for managers, statisticians, and engineers
  • Collaborate with DS/Eng teams to evaluate LLM search algorithms; design human evaluations and leverage automated benchmarks
  • Test and provide feedback on new relevance algorithms and features; run experiments and write crisp readouts
  • Analyze metrics and query logs to diagnose and resolve relevance and data quality issues; drive cross‑functional fixes

What you'll bring

  • 3+ years of data analysis experience; strong proficiency in SQL, Python, and BI tools (Tableau or similar)
  • Hands‑on exposure to LLMs and evaluation techniques (human judgments, rubrics, automated benchmarks)
  • Ability to work cross‑functionally with Design, Product, Editorial, Safety, and Engineering; you move projects forward under tight deadlines
  • Sharp analytical and problem‑solving skills; you love details and know how to prioritize
  • Excellent interpersonal, verbal, and written communication
  • A track record of continuous process improvement and collaborative delivery
  • Deep knowledge of Japan's music/movies/media landscape and cultural context; you can speak for local users
  • Language: Native/Fluent Japanese and Business‑level English

Nice to have
Experience in information retrieval, relevance, A/B testing, annotation/labeling ops, ML evaluation frameworks; degree in CS, Statistics, or related field; media or consumer internet experience.
