Membrane Protein Biochemist (Research Scientist/Senior Scientist DOE)

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 Membrane Protein Biochemist (Research Scientist/Senior Scientist; depending on experience) to work within the Biology Mass Spectrometry team. The company offers a thriving and creative environment for a well-suited candidate to become an integral part of our future vision.

The successful candidate will possess experience in membrane protein expression and purification. Experience in handling protein samples and characterising expression levels and activity is key. You will be responsible for developing methods to isolate proteins of interest and utilising state-of-the-art MS based methods to (i) provide a greater understanding of membrane proteins of interest and (ii) contribute to the development of a bespoke discovery platform for challenging drug targets. Experience with biophysical analysis and assay development would be advantageous, along with a desire to develop skills in advanced MS techniques. As part of the Biology MS team, the ability to problem-solve and develop innovative solutions within projects is a key attribute required for the role. The role is based in our Oxford site.
