Research Engineer - Data

We are searching for a research engineer to own the quality and coverage of the data behind our models. You will be our in-house expert on global data, ensuring our models perform exceptionally well across dozens of languages. You have a keen eye for linguistic nuance and a passion for building inclusive and representative datasets at scale.

Responsibilities:

• Design and build large-scale datasets for model training and run controlled modelling experiments to measure their impact on model performance and behaviour.
• Build evaluations of speech models, both via manual annotation and at scale with automated metrics.
• Implement techniques for steering data generation to improve model intelligence through data and mitigate bias.
• Build automated quality control systems to validate and filter generated data.
• Partner with product teams to ensure support for key languages and markets.

Requirements:

• Experience building or working with large multilingual datasets.
• Experience with generative models (speech, text, or multimodal).
• Ability to help guide human annotation and evaluation across multiple languages.
• Strong applied ML background with a focus on data-centric approaches.
• Excitement for building scalable systems that bridge research and production.
