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.
