Do you want to make a difference while advancing your career? Come join Osler.

We are a UK diagnostics company whose purpose is to enable anyone, anywhere, to access, understand, and act on their health, to live healthier, happier, and longer lives.

We are realising this through the development of the Osler Origin – a 'portable lab' capable of performing a wide range of testing, with lab-quality performance, in a portable, rapid, low-cost, and easy-to-use manner. The Osler Origin will offer a wide portfolio of diagnostic tests and serve all major healthcare settings, globally.

The Osler Origin is powered by a portfolio of novel techniques and approaches for sample addition, microfluidic sample preparation, and electrochemical biosensing, and Osler was formed out of the University of Oxford in 2017, following decades of research.

Having recently completed an $85m Series C fundraise, we are now entering a growth phase, where we are scaling our team as we take the Osler Origin product through regulatory activities, and towards market launch.
