The role emphasizes real-world experimentation, collaboration across teams, and hands-on coding with AI tools to improve speech recognition and synthesis across languages.

Qualifications

• Master's or PhD in Linguistics, Cognitive Science, or a related field.
• Specialization in phonetics, acoustics, psycholinguistics, or cognitive science.
• 4+ years of experience in large-scale experiment design and quantitative research in an industry setting.
