The Language AI Services Team in Amazon Web Services (AWS) is seeking a Language Data Scientist to join our data team focused on Health AI.

We are looking for candidates who have a strong interest in applying their linguistic and data science expertise in collecting and analyzing natural language and human data to lead multiple data collection and data analysis efforts at a time in an exciting, fast-paced environment. In this role, you will curate, engineer, and analyze natural language datasets in the medical domain, as well as design experiments and surveys to elicit human-in-the-loop insights, which are critical for developing AI-powered language applications. You will partner closely with talented language engineers, program managers, clinical experts, applied scientists, engineers, and product managers to deliver data solutions that meet customer needs.

Key job responsibilities
- Translate business, modeling and ethical requirements in Health AI into executable data collection projects
- Design human-in-the-loop evaluation tasks to measure the performance and usability of models in the medical domain
- Develop the materials necessary to execute successful data collection efforts such as guidelines, annotation interfaces, quality assurance workflows
- Support the sourcing and/or creation of high-quality language datasets and language artifacts for feature and language expansion
- Analyze structured and unstructured data to provide actionable recommendations to improve data quality or model performance
- Iterate and innovate on data collection methodologies to improve data turnaround time and reliability
- Incorporate LLMs, prompt engineering, and ML techniques to automate repetitive annotation and data creation workflows
- Stay up to date with developments in the world of AI, with a focus on model fine tuning and evaluation data needs and techniques

A day in the life
As a Language Data Scientist on the data team, you will take the lead on a couple of critical data projects related to AWS HealthScribe and Amazon Transcribe Medical, diving deep and developing materials to drive these projects forward. You will consult with stakeholders to understand the role data plays in developing and launching specific language services that meet customer needs. You will propose data collection and annotation strategy to curate and validate datasets, and partner with stakeholders to set the quality bar for these data projects. You will lead iterative data analysis and course correction efforts to address gaps and quality issues. You will also design experiments to elicit human-in-the-loop insights (including users who are domain experts) for model evaluation and usability testing, proposing the optimal business and evaluation metrics to use.

You will gradually expand your scope by applying the principles of data-centric AI to conduct experiments to drive workflow and process improvements, with the goal to optimize the cost and quality of data. Leveraging your hands-on data analytics skills and up-to-date knowledge of machine learning (ML) and Generative AI techniques, you will collaborate with other language engineers and scientists to propose new strategies for sourcing ground truth data or generating reliable metrics, automating where appropriate.
