About Owlstone

Owlstone Medical has developed a breathalyzer for disease.

Every time you breathe out there are hundreds of chemicals on your breath - some are tell-tale markers of disease that our microchip chemical sensor technology is able to detect.

Our vision is to change the way we currently diagnose and monitor serious disease; we aim to become the global leader in the non-invasive detection of cancer, infectious disease and inflammatory disease. The key is detecting diseases earlier, when treatments are more effective, where more lives can be saved. There is no better example than cancer, where if detected early the chances of survival can be as good at 95% but at late stage drop to about 5% - unfortunately there are still far too many people detected at late stage.

The Owlstone group also commercialises a range of highly innovative products based on its proprietary FAIMS chemical sensing technology in other markets including Scientific, Industrial Process Control, Military and Homeland Defence.

We offer a relaxed, friendly, flexible and international working environment with a great team-spirit. You will be rewarded with a competitive salary package that includes future share options and your work will have a clear impact on people’s lives. If you want to experience the buzz of an expanding company set to succeed on a global scale, Owlstone may be the place for you.
