• As a Principal Engineer, you will help establish the engineering vision and act as the translator between strategic intent and scalable execution. • This role drives technical direction and engineering strategy across enterprise engineering platforms by building the "paved path" - with a particular focus on developer experience, platform observability, and design and content enablement used by the QMARS team. • The Team you will be joining: QMARS • Our team is charged with maintaining and improving the software at the Centers for Medicare and Medicaid Services (CMS) that supports the Quality Management and Review Systems (QMARS) program. QMARS online case management system supports the CMS Beneficiary and Family-Centered Care (BFCC) Quality Improvement Organization (QIO) program. The QIO program is one of the largest federal programs dedicated to improving healthcare quality for Medicare beneficiaries across the country. • Our teams will continuously strive to modernize these systems while improving them in ways that reduce provider burden and minimize costs to CMS. We do this through HCD and Service design practices, product thinking, and skilled engineering. At Bellese, we’re relentlessly focused on enabling and empowering providers to focus on improving the quality and safety of patient care.
