Lead Data Scientist

About this role

• We’re hiring a Lead Data Scientist to anchor one of the most important bets in our next chapter
• Fullscript is building intelligence trained on real-world functional outcomes. Not textbook data. Not controlled trials. Real longitudinal practitioner data layered with our own prescribing and lab history
• The hard part isn’t building models. It’s designing research that can credibly claim causality in messy, non-randomized healthcare data. Can we say that Protocol X led to Outcome Y, and stand behind it with confidence?
• You’ll define how we approach causal research, set the methodological standard, and turn complex clinical data into insight the business can actually use.
• The output of this role will shape product direction, influence executive decisions, and determine whether this initiative becomes foundational to the company’s future
• This is a high bar. We’re looking for someone who’s comfortable owning it
• Designing rigorous observational research frameworks that move beyond correlation toward defensible causal inference
• Addressing confounding, selection bias, missingness, and other structural challenges in real-world healthcare data
• Extracting outcome intelligence from newly acquired longitudinal practitioner datasets
• Connecting prescribing patterns, lab data, and behavioral signals into coherent analytical narratives
• Establishing methodological standards that protect the integrity of our claims
• Translating complex statistical findings into clear implications for Product, Marketing, and executive stakeholders
• Leading and mentoring a small data team while remaining deeply hands-on in research and modeling
• Building repeatable research processes that can scale as new data flows in
