OMass Therapeutics is an early stage drug discovery company specialized in applying state of the art biophysical platform technologies to discover therapies for severe unmet medical needs in immunology and genetically defined disorders. The company was founded by Professor Dame Carol Robinson to leverage her pioneering work in native mass spectrometry, in studies of dynamic protein assemblies, to characterise challenging drug targets including membrane proteins. The high resolution of our biophysical platform offers an unprecedented advantage in the detection of drug leads.

The company vision is to build an integrated drug discovery company, with biophysical platform technologies at its core, and develop a pipeline of novel therapies. Our ambition is to develop and ultimately commercialise our products.

Following successful Series A funding, the company is expanding significantly in different areas. This is an excellent time to join a dynamic growing company.

OMass Therapeutics is inviting applications for the position of Medicinal Chemist (Senior Scientist II / Principal Scientist depending on experience). This is an exciting opportunity to participate in cutting edge drug discovery and undertake an extremely dynamic and diverse role as OMass seeks to expand medicinal chemistry capabilities. The company offers a thriving and creative environment for a well-suited candidate to be exposed to the drug discovery and development process and state-of-the-art technology developments. You will acquire extensive knowledge of the company’s operations and become an integral part of our future vision.

The successful candidate will have expert synthetic organic chemistry and medicinal chemistry knowledge and be passionate about applying these skills to the discovery of novel medicines. You will have a proven track record of scientific achievement and of delivering high quality candidates into development. The role is based in our Oxford site.
