Postdoctoral Fellow (Data Engineering & AI/ML)

The Post-Doctoral Fellow I provides assistance to the Principal Investigator, Co Investigators, and Research Staff.

Responsibilities

• 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.
• About the Project 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.
• ETL pipelines that ingest multimodal datasets (wearables, cross-referenced with EHRs, PSGs, and subjective sleep metrics), ensuring efficient storage, retrieval, and processing of massive datasets (+1million records)
• Support the build-out of scalable infrastructure to support advanced machine learning models using physiological features and sleep microarchitectures
• Optimize application performance and scalability through performance tuning, code refactoring, and database optimization techniques
• Stay updated with emerging industry trends, academic literature, and technologies in data engineering, cloud architecture, and machine learning to continuously improve the lab’s technical capabilities
• Ensure data integrity throughout engineering workflows.
• Assist in the preparation of Standard Operating Procedures (SOPs), analytical frameworks, and technical documentation
• Maintain open communication with leadership, advise on technical processes, and curate progress reports
• Provide technical support and oversight to team members with less experience
• Assist in regulatory support, Data Sharing Agreements, and other project documentation
• Collaborate and assist the Principle Investigator, Co-Investigators and research team in the performance the research study
• Contribute to the drafting and submitting of abstracts, manuscripts and reports for dissemination
• Prepare progress reports on research as required
• Analyze and write-up data
• Present complex information effectively to a range of audiences
• Provide data management assistance
• Provide project close-out suppo

Requirements

• 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

• 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
• Knowledge of military system, preferred.

Demonstrate competence in oral and written communication

• Must be organized, attentive to detail, and possess a positive, friendly and professional demeanor
• Ability to be flexible with changing priorities and available to interact with employees, clients and sponsors of all levels
• Ability to exercise independent judgment in fast-paced, high-pressured environment with strict deadlines and to manage multiple projects
• Computer skills including at least intermediate level experience with Excel and other Microsoft Office Software Responsibilities Design, develop, and deploy scalable applications (both front-end interfaces and back-end data pipelines) to support large-scale research

Pay

• Salary Range $36.00/HOUR.
• 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.
