Department Summary:

Background:

We are recruiting postdoctoral scholars for the NIH-funded T32 Postdoctoral Training Program in Translational Population Health and Data Science Using Service Member, Veteran and Civilian Healthcare Datasets.

Virginia Commonwealth University (VCU) and the Central Virginia VA Health Care System have partnered to create a unique big data analytics post-doctoral training program that includes didactic and experiential learning and training in use of large Veteran as well as civilian datasets. The program includes development and implementation of advanced analytics methods, not limited to machine learning methods and Artificial Intelligence.

As the commonwealth’s capital, Richmond, Virginia, offers a vibrant mix of history, culture and real-world opportunities. Distinct neighborhoods, cozy restaurants and cafes and quaint local markets give the city an intimate feel, but theaters, galleries, music festivals, sports attractions and a steady stream of annual events bring RVA — as locals call the region — to life.

Description of the Opportunity:

This T32 program will prepare postdoctoral fellows with the skills and competencies in Big Data Analytics (BDA) methods and techniques to support Evidence-Based Medicine (EBM). The datasets that will be available to the new T32 fellows will be among the largest in U.S. health care. The VA Corporate Data Warehouse holds detailed health care records on approximately 25 million veterans spanning the past 25 years, with roughly 4 billion additional data points added each day. Centers for Medicare and Medicaid Services datasets, housed at VCU through the Center for Rehabilitation Science and Engineering Data Hub, cover more than 65 million Americans enrolled annually in Medicare programs. The training program is co-led by Virginia Commonwealth University and Central Virginia Veterans Affairs Health Care System. The overarching objective of this 5-year T32 training program is to recruit and train a skilled cohort of postdoctoral fellows (MD, DO, PhD, ScD) who will develop competencies and build capacity in real-world evidence translation for service members, Veterans and civilians using population health and data science approaches.

Potential novel areas of focus include:

  • Health services utilization and outcomes for beneficiaries on Medicare and Medicaid programs
  • Assessing health of service members transitioning from DoD to VA care
  • Exploring healthcare utilization and outcomes of dually-enrolled (CMS/VA) Veterans
  • Harmonizing CMS-VA-DOW datasets to understand the complex needs and outcomes of these populations
  • Comparing risk and protective factors for healthcare utilization and outcomes between civilians and military veterans
  • Informing civilian population and individual-level interventions, research programs, and policy
  • Examining quality of services across military, veteran and civilian healthcare systems

The primary appointment for the fellows will be in the Department of Physical Medicine and Rehabilitation (PM&R) in School of Medicine at VCU which is one of the most well-established PM&R departments in the country and has received international recognition for neurorehabilitation, including stroke, brain and spinal cord trauma research. The 70+ VCU PM&R faculty, including physicians and psychologists, provide clinical, research and teaching across VCU Health, SAI, Children’s Hospital of Richmond and Central Virginia Veterans Affairs Health Care System. The Department also has 7 post-graduate fellowship training programs in TBI/Polytrauma, Amputation, SCI, Pain Management, Integrative Medicine, Sports Medicine and Rehabilitation Research.

The position is affiliated with VCU’s Center for Rehabilitation Science and Engineering (CERSE) and the Wright Regional Center for Clinical and Translational Science. VCU and CERSE provide a rich training environment including a commitment to creating a supportive mentoring environment, didactic and hands-on research training, a broad local and national mentorship network, large datasets for analyses, statistical support, and individualized professional development opportunities.

Program Activities:

Our program will recruit fellows from both PhD/ScD and MD/DO tracks. Each fellow will participate in two years of training activities. Upon training program completion, each fellow is expected to:

  • understand responsible conduct of research with use of population health datasets, claims, survey data, and data from Electronic Health Records (EHR),
  • develop grant writing skills needed to be competitive for external grant funding,
  • understand the fundamentals of translational population health and data science research studies in terms of study design, dataset identification, data management and analysis, and dissemination of results,
  • perform hypothesis-driven translational research by developing a multi-disciplinary team,
  • disseminate study findings via scientific peer-reviewed publications/presentations, and
  • complete coursework and training in the design and conduct of rigorous, controlled research studies.

As appropriate for individuals’ career goals, proposed activities mentioned above and research experience will be supplemented by a series of additional activities designed to intensify and enhance the abilities of trainees to conduct translational population health and Data Science-related research studies using service member, Veteran and civilian healthcare datasets. Our program’s didactic options include: (a) recommended formal coursework as applicable; (b) formal master’s degree program as applicable; (c) seminar and workshops; and (d) grant writing institute and workshops.

The primary fellowship goals are to develop a publication portfolio in the fellow’s line of research, work towards seeking a research faculty or research position, and prepare preliminary materials for a research career development or other grant application that the fellow can use in their subsequent role.

Mentoring Team:

Fellows will also work with a combination of mentors from different health domains and those with methodological expertise from the VCU schools of Medicine, Nursing, Dentistry, Pharmacy, and Public Health; the College of Engineering; the College of Health Professions; and Central Virginia Veterans Affairs Health Care System.

Location VA, US
Category AI/ML Engineer
Experience Mid Level
Salary Not disclosed

About This Role

AI/ML Engineers build and deploy machine learning models in production. They work across the full ML lifecycle: data pipelines, model training, evaluation, and serving infrastructure. The role has evolved significantly over the past two years. Where ML Engineers once spent most of their time on model architecture, the job now tilts heavily toward inference optimization, cost management, and integrating LLM capabilities into existing systems. Companies want engineers who can ship production systems, and the experimenter-only role is fading fast.

Day-to-day, you're writing training pipelines, debugging data quality issues, setting up evaluation frameworks, and figuring out why your model performs differently in staging than it did on your dev set. The best ML engineers are obsessive about reproducibility and measurement. They instrument everything. They know that a model is only as good as the data feeding it and the infrastructure serving it.

Across the 9,079 AI roles we're tracking, AI/ML Engineer positions make up 76% of the market. At Virginia Commonwealth University, this role fits into their broader AI and engineering organization.

Demand for AI/ML Engineers has been strong and consistent. Unlike some AI roles that spike with hype cycles, ML engineering is a foundational need. Every company deploying AI models needs people who can keep them running, and the gap between research prototypes and production systems keeps growing.

What the Work Looks Like

A typical week might include: debugging a data pipeline that's silently dropping 3% of training examples, running A/B tests on a new model version, writing documentation for a feature flag system that lets you roll back model deployments, and reviewing a junior engineer's PR for a new evaluation metric. Meetings tend to be cross-functional since ML touches product, engineering, and data teams.

Skills in Demand for This Role

Python (18% of roles) Aws (10% of roles) Azure (8% of roles) Rag (7% of roles) Gcp (6% of roles) Pytorch (5% of roles) Claude (5% of roles) Kubernetes (4% of roles)

Python and PyTorch dominate the requirements. Most roles expect experience with cloud platforms (AWS, GCP, or Azure) and familiarity with ML frameworks like TensorFlow or JAX. RAG (Retrieval-Augmented Generation) has become a top-3 skill requirement as companies integrate LLMs into their products. Docker and Kubernetes show up in about a third of postings, reflecting the production focus of the role.

Beyond the core stack, employers increasingly want experience with experiment tracking tools (MLflow, Weights & Biases), feature stores, and vector databases. Fine-tuning experience is valuable but less common than you'd think from reading Twitter. Most production LLM work is RAG and prompt engineering, not fine-tuning. If you have both, you're in a strong position.

Companies that are serious about AI/ML hiring tend to post specific infrastructure details in the job description: the frameworks they use, their model serving stack, their data pipeline tools. Vague postings that just say 'ML experience required' without specifics are often companies that haven't figured out what they need yet.

Compensation Benchmarks

Career Path

Common paths into AI/ML Engineer roles include Data Scientist, Software Engineer, Research Engineer.

From here, career progression typically leads toward ML Architect, AI Engineering Manager, Principal ML Engineer.

The fastest path into ML engineering is through software engineering with a self-directed ML education. A CS degree helps, but production engineering skills matter more than academic credentials. Build something that works, deploy it, and measure it. That portfolio project is worth more than a Coursera certificate. For career growth, the fork comes around the senior level: go deep on technical complexity (staff/principal track) or move into managing ML teams.

What to Expect in Interviews

Expect system design questions around ML pipelines: how you'd build a training pipeline for a specific use case, handle data drift, or design A/B testing infrastructure for model deployments. Coding rounds typically involve Python, with emphasis on data manipulation (pandas, numpy) and algorithm implementation. Take-home assignments often ask you to build an end-to-end ML pipeline from raw data to deployed model.

When evaluating opportunities: Companies that are serious about AI/ML hiring tend to post specific infrastructure details in the job description: the frameworks they use, their model serving stack, their data pipeline tools. Vague postings that just say 'ML experience required' without specifics are often companies that haven't figured out what they need yet.
