Staff Hardware Reliability and Test Engineer



Other Engineering, Quality Assurance
San Francisco, CA, USA
Posted on Monday, March 13, 2023

Headquartered in San Francisco, CA, Cytovale is a dynamic, late-stage startup focused on developing a faster, more insightful way to diagnose fast-moving and immune-mediated diseases. Cytovale’s IntelliSep test is pioneering a new way of quickly and accurately analyzing white blood cells to stratify a patient’s risk of sepsis. The test simply and clearly determines risk of sepsis using a biomechanical evaluation of white blood cells collected from a standard blood draw, generating results in under 10 minutes. This gives physicians actionable information when they need it most, allowing them to confidently triage suspected sepsis patients quickly and spend more time with those in greatest need. It also helps strained health systems prevent unnecessary treatment, preserve valuable resources, and improve compliance with Sep-1 guidelines.
