Job description

This role is with a 50 person startup looking for someone who can commute to Cambridge, MA 3-4 days per week. Thanks for applying!

The org builds patient engagement platforms, clinical workflow tools, and healthcare systems that help patients and care teams stay connected throughout treatment.
