The Speech Data Engineer is a key specialist bridging the data market with our technological needs. You will be responsible for identifying unique data sources, evaluating their quality, and building strong relationships with data providers.

Requirements

* Hands-on experience with speech data processing and labeling tools, such as VAD, Pyannote, whisper, and other segmentation or diarization frameworks.

* Familiarity with quality assessment metrics, including SNR (Signal-to-Noise Ratio) and other acoustic analysis indicators.

* Collect, process, and curate speech datasets, including audio recordings, transcripts, and metadata for multilingual ASR and TTS applications.

* Work closely with internal ASR/TTS development teams to align dataset specifications with model training needs.

* Label and validate audio data, ensuring transcription accuracy, speaker diversity, and consistent metadata standards.

Responsibilities

* Organize, version, and maintain speech datasets, ensuring teams always know what data exists and where it lives.

* Support existing data infrastructure and pipelines (e.g. DVC).

* Work with external data providers, evaluating dataset quality and contributing to make-vs-buy decisions.
