Who We Need

Truveta is rapidly building a talented and diverse team to tackle complex health and technical challenges. Beyond core capabilities, we are seeking problem solvers, passionate and collaborative teammates, and those willing to roll up their sleeves while making a difference. If you are interested in the opportunity to pursue purposeful work, join a mission-driven team, and build a rewarding career while having fun, Truveta may be the perfect fit for you.

This Opportunity

We are seeking a Principal Biostatistician to join our team and play a key role in advancing the use of large language models (LLMs) in healthcare data analysis. In this role, you will be responsible for evaluating the performance of LLMs in extracting data from unstructured clinical documentation originating in electronic health record (EHR) systems, validating the accuracy and consistency of that data, and developing code and analytical tools that enable customers to seamlessly use the extracted outputs combined with other semi-structured data sources in their scientific studies.

The ideal candidate will combine strong statistical expertise with programming skills and a deep understanding of real-world data (RWD), data quality, and validation methods. You will collaborate closely with machine learning engineers, terminologists, clinical informaticists, and data scientists to ensure that model-derived data are both statistically sound and clinically meaningful. You will also interface with customers in order to help them understand the data, how it can be used, and its limitations. The ideal candidate is highly proficient in using real-world data and advanced statistical methods, and thrives in a collaborative, data-intensive environment.

Key Responsibilities

• Lead the design and execution of statistical evaluation strategies for Truveta's AI and clinical models, ensuring rigor and reproducibility.
• Develop and apply advanced statistical methods to evaluate model performance, calibration, generalizability, and bias, especially in the context of real-world data (RWD).
• Guide the use of observational study designs and causal inference techniques to strengthen model evaluation using RWD.
• Partner closely with clinical, data science, and product teams to define evaluation criteria that align with clinical relevance, patient outcomes, and regulatory standards.
• Provide expertise on data quality, missingness, confounding, and heterogeneity in RWD to ensure robust evidence generation.
• Communicate statistical insights and evaluation results effectively to technical teams, clinicians, external stakeholders, and research collaborators, influencing model improvement, validation, and adoption.
• Stay current with evolving best practices in biostatistics, machine learning evaluation, and RWD methodologies, and mentor teams on their application.

Required Skills

• Master's or Ph.D. in Biostatistics, Mathematics, Epidemiology, Health Economics, Data Science, or related field.
• 7+ years of applied statistical experience with EHR and/or claims data (e.g., Optum, MarketScan, Flatiron, Epic, Oracle Health (formerly Cerner), CMS).
• Strong programming skills in R and SQL; experience with Python, PySpark, or Databricks a plus.
• Proven expertise in working with structured health data using medical ontologies such as ICD-10, CPT, NDC, LOINC, SNOMED CT, and RxNorm.
• Experience with statistical methods to evaluate:
• Performance metrics such as precision, recall, F1 score
• Agreement and Reliability
• Error and Bias
• Robustness
• Strong communication skills (written and verbal)

Preferred Qualifications

• Experience supporting regulatory-grade Real World Evidence (RWE), Health Outcomes, or payer-facing studies.
• Exposure to clinical phenotyping, NLP, or unstructured data integration.
• Ability to translate statistical output into clinically meaningful insight.
• Proactive communicator, comfortable working across teams and customers. Strong documentation habits and commitment to reproducibility.
