• Support the delivery of high-quality curated audio data that ensures clear, natural spoken output, accurate representation of linguistic and prosodic details (such as intonation, rhythm, and accent), and professional audio standards
• Collaborate with technical staff to develop tasks that improve AI's ability to handle speech modulation, accent variation, noise in real-world recordings, and multilingual audio processing
• Work with technical staff to improve annotation tools for efficient audio workflows

Skills

• Native proficiency in Polish with exposure to diverse accents, dialects, or regional variations
• Proficiency in English (minimum B2 level) with clear, natural vocal delivery and pronunciation suitable for audio recording purposes
• Strong auditory perception to identify nuances in speech, accents, pronunciation, intonation, and audio quality across languages
• Demonstrated ability to handle multilingual audio content, including evaluating speech accuracy, cultural vocal expressions, and contextual interpretation in spoken form
• Demonstrated ability to transcribe audio with high accuracy across accents and varying audio quality
• Comfort providing high-quality voice recordings and feedback on audio samples in multiple languages
• Strong comprehension skills and the ability to make independent judgments on ambiguous or varied audio material, including noisy or accented speech
• Strong communication, interpersonal, analytical, detail-oriented, and organizational skills, with the ability to articulate audio-related feedback effectively
• Commitment to developing AI that masters sophisticated multilingual audio capabilities
• Demonstration of exceptional attention to linguistic nuance, auditory detail, and data quality beyond standard transcription work

• Strong command of advanced transcription and annotation practices, including handling disfluencies, accents, and prosodic features (intonation, stress, rhythm, emotion, etc) with high consistency and accuracy
• Background in linguistics (e.g., phonetics, phonology, sociolinguistics), speech sciences, cognitive science, or a related field, or equivalent practical experience, with demonstrated ability to analyze accent variation, pronunciation differences, and multilingual speech patterns
• Experience working with speech/audio datasets, annotation workflows, or AI training data, including knowledge/experience with training voice models, and an understanding of how data quality impacts model performance
• Professional experience in voice work, including voice acting, voice recording, podcasting with a measurable audience (e.g., X following), or similar audio production demonstrating attention to clarity and recording quality
• Demonstrated ability to exercise independent judgment in ambiguous audio scenarios and make consistent, defensible annotation decisions
• Portfolio (strongly preferred for advanced candidates): Voice samples, annotated transcripts, or audio-related work demonstrating quality, methodology, and attention to detail
• Candidates with professional experience in voice, linguistics, speech data, or speech evaluation and research are especially encouraged to apply

Benefits

• Benefits vary based on employment type, location, and jurisdiction.
• Benefits for eligible U.S.-based positions include health insurance, 401(k) plan, and paid sick leave.
• Specific details and role-specific information will be provided to you during the interview process.
