Senior Scientist, Real-World Evidence and Outcomes

Circadia Health is a growth-stage healthcare AI company on a mission to prevent avoidable hospitalizations and transform senior-care operations. Our Circadia Intelligence Platform combines contactless sensing, predictive models, and enterprise integrations to monitor 40,000+ post-acute patients daily across skilled-nursing, home-health, and home-care networks.

About the role

You will design and run studies that establish what Circadia's platform does for patients and for cost. This includes framing study questions, choosing designs, running analyses, and publishing findings on metrics such as hospital readmission rates, fall rates, time to clinical intervention, emergency department and inpatient utilization, length of stay, total cost of care, and clinician productivity. As the first dedicated outcomes research hire, you will own both clinical evidence and health economics, setting the standard for how Circadia substantiates claims.

Responsibilities

• Scope studies of the deployed platform: define the question, cohort, observation period, and endpoints from operational data.
• Choose and defend study designs where randomization is not available (e.g., retrospective observational, matched cohort, difference-in-differences, interrupted time series, index-event designs).
• Build comparison groups, baselines, and risk-adjustment approaches that hold up under external scrutiny.
• Write prespecified analysis plans and decide up front what a study will and will not claim.
• Own IRB submission, human-subjects determination, and conflict-of-interest/AI-assistance disclosure.
• Shape how future deployments collect data to ensure publishability by design.
• Analyze Medicare claims, EHR, platform, and customer operational data using matching and causal inference methods (e.g., propensity score matching, mixed-effects models).
• Reason about confounding, selection bias, immortal time bias, and balance diagnostics to defend study defensibility.
• Translate Circadia’s operations and billing into claims-detectable logic (e.g., NPIs, place of service, RPM/RTM CPT codes, type-of-bill logic).
• Define how Circadia calculates and reports ROI and cost avoidance, including subgroup analyses.
• Draft and publish manuscripts in journals such as JAMDA and JAMIA, and manage peer review and revision.
• Produce conference abstracts, white papers, and commercial evidence without letting claims drift between versions.
• Set guardrails on what Circadia can and cannot claim from its evidence.
• Present findings to clinical, payer, and executive audiences, and support customer and partner conversations.

Requirements

• MSc or PhD in epidemiology, health services research, biostatistics, health economics, public health, or a related quantitative field.
• 5+ years producing real-world evidence, outcomes research, or health economics work in a company, consultancy, payer, or provider setting.
• Experience with health economics and outcomes research, including cost, utilization, ROI, or cost-avoidance analysis alongside clinical endpoints.
• Ability to translate technical findings into clear narratives for executives, customers, and payers.
• Track record of peer-reviewed publication, ideally in a clinical specialty or informatics journal.
• Command of observational and quasi-experimental study design, with clear thinking about its limits.
• Proficiency with R or Python and SQL, and comfort with large, messy healthcare datasets.
• Clear scientific writing and experience carrying a manuscript through peer review.

Preferred Qualifications

• Experience with Medicare, Medicare Advantage, skilled nursing, or senior care populations.
• Working knowledge of Medicare claims structure and CMS post-acute quality measures (e.g., SNFRM, PPR).
• Experience in remote patient monitoring, medical devices, or digital health.
• Experience evaluating AI or machine learning models in a clinical workflow.
• Experience measuring clinician workload, documentation burden, or workflow efficiency.
• Startup experience.
• Familiarity with IRB pathways and reporting standards such as SQUIRE 2.0.
• Experience working with actuarial firms or third-party claims datasets.
• Understanding of value-based care economics and healthcare reimbursement.
