Location: San Jose, CA, United States
Position Type: Unfixed Term
Job Function: Bioscience R&D

A family-owned company, bioMérieux has grown to become a world leader in the field of in vitro diagnostics. For almost 60 years and across the world, we have imagined and developed innovative diagnostics solutions to improve public health. Today, our teams are spread across 44 countries and serve 160 countries with the support of a large distribution network. This includes our SLC site, formerly known as BioFire Diagnostics.



The world is facing a medical crisis, bacteria are increasingly evolving resistance to even our strongest antibiotics. The problem is already very real and immediate; for example, bloodstream infection leading to sepsis is now responsible for more than half of all deaths in hospitals and is the most expensive condition treated in hospitals. Sepsis mortality rate increases >6% every hour without effective antibiotic treatment. Yet, despite the life and death urgency, and healthcare cost impacts, current methodologies require 3 days to determine the correct antibiotic.

Specific Diagnostics, a bioMerieux company, has developed a breakthrough solution to rapidly determine the effective antibiotic treatment for bloodstream and other acute infections. Used for bloodstream infection Specific’s solution provides results 2 days sooner (1 day vs 3 days).

We offer an opportunity to join us at an inflection point in our commercial growth, with our first commercial product being released new venture capital funding and recognition from major customers and government agencies fueling an expansion of our staff.
