OMass Therapeutics specialises in applying state-of-the-art native mass spectrometry platforms to characterising challenging protein assemblies, including membrane proteins. By preserving the structures of protein assemblies we provide novel structural insights into large, dynamic complexes. The company vision is to build a drug discovery company with these technologies at its core.  

OMass Therapeutics is inviting applications for the position of Native Mass Spectrometrist, focussed on developing new platforms for drug discovery. This is an exciting opportunity to undertake an extremely dynamic and diverse role within a new biotechnology spin-out company from the University of Oxford. The company offers a thriving and creative environment for a well-suited candidate to be exposed to drug discovery and development processes 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. 

At OMass Therapeutics you will join a team of enthusiastic and dynamic scientists with a shared passion for building a world-leading drug discovery company using an exciting and powerful set of technologies. Following a recent successful fund-raising exercise, the company is expanding significantly in different areas and has recently relocated to a new building at the Oxford Science Park. This is an excellent time to join a growing company. 

The successful candidate will possess previous experience in the applications of mass spectrometry, using native MS based methods for understating protein interactions. You will be responsible for developing native MS platforms for the analysis of membrane proteins and optimising them for a range of challenging drug targets. Experience of molecular biology, protein expression/purification is advantageous. The role is exclusively research based and as such, the ability to problem solve and develop innovative solutions within projects is a key attribute required for the role. 

Applications to be received by 12th December 2018  


  • Proven experience at post-doctoral level in native mass spectrometry, preferably on orbitrap or QTOF based platforms.
  • Hold a doctorate degree in chemistry, biochemistry or other life sciences
  • Experience with handling protein samples; some experience with protein expression and purification are preferred but not essential
  • Excellent communication skills, both written and verbal 

Role Responsibilities 

  • Develop native MS platforms for the analysis of purified membrane protein samples
  • Optimise sample conditions and buffers to obtain suitably homogeneous spectra
