Audio Engineer

Innodata Inc.

7d • $120,000 - $160,000

About The Position

Innodata is a global data engineering company focused on enabling the responsible advancement of artificial intelligence. We provide data, evaluation frameworks, and human expertise for building trustworthy AI systems. Our mission is to deliver high-quality data and outstanding outcomes, building on our 36+ year legacy. This role is central to producing the voice and audio datasets behind leading speech AI, focusing on the technical aspects of signal chain, post-processing, technical specifications, and consistent acoustic quality.

Requirements

• Strong audio engineering background: signal chain, recording, post-processing, mastering, and acoustic QA.
• Deep fluency in audio technical specs (sample rate, bit depth, LUFS, formats, codecs) and the ability to define and enforce them.
• Experience producing consistent audio quality across varied recording conditions and locations.
• Comfort with audio tooling and automation (scripting for batch processing/QA is a strong plus).
• Precision and process orientation — you care about consistency at scale, not just one great recording.
• Experience with speech/voice data for AI/ML (TTS or ASR datasets).
• Familiarity with multilingual recording and remote/distributed capture.
• Knowledge of speech quality metrics and how acoustic choices affect downstream model performance.
• Scripting (Python) for audio processing pipelines (e.g., ffmpeg, sox, pydub, librosa).

Responsibilities

• Own the end-to-end audio signal chain and post-processing pipeline for all collection programs.
• Define and document technical specifications: sample rates, bit depth, formats, loudness (LUFS) targets, noise floors, channel configurations.
• Design and maintain the “Innodata sound signature” — a consistent, spec-compliant acoustic profile across studio, remote, real-world, and telephonic captures.
• Build technical QA: automated and manual checks that validate audio against spec before delivery.
• Specify and validate recording setups for vendors and remote contributors (signal-chain testing in a small in-house studio).
• Partner with the Solutions Architect to translate customer acoustic requirements into achievable technical recipes.
• Drive tooling: help select and configure recording/QA/processing tools; automate where possible.
• Troubleshoot acoustic and signal issues across diverse capture environments.
