• Proficiency with CAT tools and QA workflows (translation memory, termbases, automated checks) and comfort working with structured guidelines.
• Excellent editorial judgment (register, tone, inclusivity, and cultural nuance) with extreme attention to detail.
• Ability to rigorously fact-check localized content (units, references, names, dates) using reliable sources and consistent reasoning.
