Senior Data Engineer

Senior Data EngineerAs a Senior Data Engineer at Regard, you'll own the design, development, and production deployment of the data services that power the Regard platform. From ingesting and standardizing clinical data across health systems to making it reliably available for downstream product, analytics, and AI research workflows, you'll build and evolve the infrastructure that enables the platform. You'll help set the technical direction for the data team — designing lakehouse architecture, leading experimentation with processing and storage approaches, and mentoring engineers — while remaining hands-on with implementation and production delivery. We prioritize transparent, code-driven systems over black-box services, and you'll help architect the data platform that supports that philosophy.Regard's mission is to bring world-class healthcare to everyone. Our technology reasons through a patient's entire medical record to recommend diagnoses that would otherwise be missed, in real time at the point of care, during chart review, and in population-wide screening to identify patients who qualify for lifesaving treatment.We work alongside some of the top health systems in the country to lead the change this industry needs.
