Postdoctoral Fellow; Data Engineering & AI​/ML

The Post-Doctoral Fellow I provides assistance to the Principal Investigator, Co Investigators, and Research Staff. S/he ensures enrollment numbers are successfully met, when applicable, and protocol adherence, monitoring visits, overseeing regulatory and administrative details, data management assistance and project close-out support is provided.

This project is a multi-institution research collaboration with Stanford, Johns Hopkins, the Veteran Affairs (VA), and the Department of War (DoW) to build a sleep foundation model. Unlike traditional AI models, a sleep foundation model relies on self-supervised learning on vast amounts of physiological sleep study data (petabyte-level). By generating representations (embeddings) from the sleep data, the team aims to forecast future health risks and uncover latent patterns that traditional sleep scoring metrics miss.

$65,000 - $79,000. Salaries are determined based on several factors including external market data, internal equity, and the candidate’s related knowledge, skills, and abilities for the position.

• PhD or MD required
• 1-2 years medical research project management experience strongly desired, preferably with Department of Defense
• 5+ years experience with multimodal data analysis
• Proven experience with signal processing (eg, time-series biosensor data)
• Hands-on experience with version control systems (eg, Git) and ability to work in a collaborative coding environment
• Experience and/or a strong desire to learn the ins and outs of cloud computing, including managing cloud-native data warehouses and standing up ETL pipelines
• Preferred qualifications:
  
  strong knowledge of sleep science, familiarity with machine learning workflows including model development, model tuning, and deploying models at scale
• Ability to work in a fast-paced, multidisciplinary, multi-site (sometimes asynchronous) team environment
