Senior QA Engineer / Senior Software Test Engineer

Medsien is the leading provider of scalable remote care management for a quality patient experience. Hundreds of organizations trust Medsien’s unparalleled technology solutions to implement exceptional remote care management programs, personalize every interaction, and improve the lives of the people who need it most. Based in San Francisco and venture-backed by top-tier investors, Medsien was founded to reimagine remote care management.

More than 60% of all U.S. adults—over 150 million people—live with at least one chronic condition, which requires dedicated, ongoing medical support outside the four walls of their doctor’s office.
