Principal Data Scientist

We are seeking a Principal Data Scientist to join Pedestal Health's Quantitative Sciences (QS) organization. In this role, you will build the infrastructure and methods that make AI-assisted analytics and real-world data quality work fast, scalable, and genuinely trustworthy.

Your work will span two connected areas. The first is AI-enabled analytics: building and maintaining AI tooling and workflows that let our team identify cohorts, review analysis code, and carry out recurring analytic work faster and more consistently. The second is AI-enabled data quality: designing automated and agentic approaches that scale across schemas, sites, and data refreshes, and that surface issues before they reach an analysis or a client.

This is a role about building capability, not about producing analyses. You will design, build, and scale the internal tools that change how our teams work with real-world data - and you will own them as products, with users, versions, quality standards, and a roadmap. This is a hands‑on role that combines individual technical contribution with technical leadership, including mentorship and review of other data scientists' work.

You will partner closely with Product, Engineering, Medical, and Commercial teams, and report to the Head of Quantitative Sciences.

• Build, maintain, and improve AI-powered tooling that lets the team generate commercial cohort counts and conduct feasibility reliably and repeatably
• Extend the same approach to other recurring analytic work, including generating and reviewing analysis code, and supporting protocol and analysis plan development
• Gather requirements from the internal teams who depend on these tools, treat them as users, and iterate on real feedback rather than assumed needs
• Own what keeps this tooling trustworthy over time (how it is tested against known‑correct results, how updates are validated before release, and how performance is monitored as the underlying data evolves), and where human review remains mandatory
• Scale adoption across the team through documentation, training, onboarding, and hands‑on enablement
• Help define the guardrails for AI use in client‑facing work: what data may be used, how outputs are reviewed and by whom, and how provenance is recorded

• Rethink how our data quality checks are built and run, so that assessing a new source or a refreshed schema no longer means redoing the work each time
• Move quality assessment beyond manual review and spreadsheet outputs, toward an automated approach with a durable record of what was checked, what was found, and how it was resolved
• Determine where AI and agentic approaches genuinely add leverage in this work, and where deterministic, reproducible checking should remain the foundation
• Define how we will know the system is working, including whether the people who receive quality signals continue to trust them and act on them
• Partner with Engineering on pipeline integration, orchestration, and monitoring

• Partner closely with Product, Engineering, Medical Science, Clinical Operations, and Commercial teams
• Advocate effectively for the quality and validation work that AI‑assisted products require, including in roadmap and prioritization discussions
• Keep pace with developments in AI tooling and methods, and actively push what proves useful into our standards, training, and tooling
• Provide technical oversight, code review, and mentorship to other data scientists, and own the standards their work is measured against
• Help grow the data science group as it expands

• MS or PhD in data science, statistics, computer science, computational biology, or a…
