* **Please note: This job is available in Bentonville, AR location only and no current or future sponsorship is available. Candidates who do not need sponsorship are strongly encouraged to apply.**

What You’ll Do

+ Design and implement AI/ML models that transform large-scale, multi-modal healthcare data (e.g., pharmacy, claims, EMR) into real-world insights and evidence.

+ Develop scalable analytical pipelines to support clinical and observational research, RWE studies, and research insights reports.

+ Apply advanced modeling techniques (predictive modeling, causal inference, NLP, graph analytics) to uncover trends and support decision-making in healthcare.

+ Collaborate with cross-functional teams (data engineers, informaticians, clinicians, statisticians) to standardize data and enhance data quality.

+ Support GenAI/Agentic AI initiatives to automate and optimize research workflows, knowledge extraction, and evidence synthesis.

+ Communicate complex results to technical and non-technical stakeholders through visualizations, dashboards, and executive-level summaries.

What You’ll Bring

+ Proven expertise in machine learning, statistical modeling, and data storytelling, with applied experience in healthcare, clinical research, or real-world data analytics.

+ Strong proficiency in Python and related data science libraries (pandas, scikit-learn, PyTorch, TensorFlow).

+ Experience working with healthcare datasets (claims, EMR/EHR, pharmacy, registries), ontologies (MeSH, OBO, DO, UMLS) and coding systems (ICD-10/11, SNOMED CT, LOINC, CPT/HCPCS, GPI, RxNorm).

+ Working knowledge of cloud platforms (Azure, GCP) and distributed computing tools (e.g., BigQuery, Databricks).

+ Proficiency with Python and SQL and data engineering concepts for handling high-dimensional, large-scale datasets.

+ Familiarity with GenAI and Agentic AI frameworks (MAF, A2A, LangChain, Azure ML, Vertex AI, etc.) is a plus.

+ Excellent communication and collaboration skills — able to translate technical findings into actionable insights for all audiences.

Preferred Qualifications

+ Master’s or PhD in Data Science, Computer Science, Health Informatics, Biostatistics, or related field.

+ Experience with RWD/RWE pipelines, tokenization, or de-identification workflows.

+ Experience in healthcare AI/ML model validation, interpretability, or regulatory-grade analytics.

+ Experience working with AI/ML software engineers, solutions architects, product managers, medical affairs, epidemiologists.

+ Publication or contribution to peer-reviewed healthcare or data science journals a plus.
