Overview
Senior Software Quality Engineers ensure product and process excellence through a strong foundation in manual and exploratory testing, paired with increasing ownership of test automation. In this role, you will begin with hands‑on manual testing to build deep domain knowledge across complex, real‑world healthcare applications and workflows. As you gain understanding of the systems, you will take responsibility for designing, implementing, and maintaining automated test coverage for critical workflows.
You will identify risk early, validate functional, usability, and compliance requirements, and contribute to the evolution of the team’s quality practices through effective use of automation. Your work directly supports the reliability and safety of software used by providers and patients in a regulated environment.
