  • Troubleshoot quality issues and resolve ambiguous requirements with clients.
  • Provide domain expertise across speech and audio workflows, advising on feasibility, evaluation methods, and tooling.
  • Build reusable guidelines, SOPs, and QA frameworks while mentoring Operations Specialists.
  • Support new project scoping, pilots, and capability development as speech and voice AI evolves.

    • What You Bring
  • 1–2+ years of experience in AI data operations, project coordination, or delivery, ideally in a GenAI or frontier AI environment.
  • Hands-on familiarity with at least one speech, audio, language, or conversational AI workflow.
  • Experience coordinating projects or workstreams, managing stakeholders, and communicating with clients.
  • Understanding of data quality, annotation workflows, and quality assurance methods.
  • Ability to turn client requirements into clear guidelines, workflows, and quality standards.
  • Strong problem-solving skills and the ability to manage multiple priorities in a fast-moving environment.
  • Interest in current AI developments and how speech, audio, and voice-agent technologies are evolving.

    • Nice to Have
  • Experience with ASR transcription, speaker diarization, acoustic annotation, or TTS evaluation.
  • Familiarity with voice-agent scripts, IVR, dialogue design, turn-taking, or conversational evaluation.
  • Experience with localization, cross-locale consistency, CJK languages, or low-resource languages.
  • Bilingual or multilingual capabilities, particularly German or a Nordic language.
