Job description

This is an exciting opportunity to join a growing and vibrant research team that combines expertise in bioinformatics and computational design, peptide and protein chemistry, biotechnology, and machine learning.  In this post you will work towards developing the technology that underpins our laboratory-based, liquid-phase, plate-reader assay towards a device for use in the clinic and at the bedside. This is an ambitious objective that will be cross-disciplinary and will require innovation, inventiveness, and lateral thinking. In addition, we are a small and nimble company with flexibility being highly valuable to us.  As such, from time-to-time, you may be required to briefly switch to working on other projects to meet broader deadlines.

We are currently advertising to fill two Senior Scientist (Chemist) posts: Both the position advertised here; and for an Analytical Chemist.  We encourage any candidates to read the description for both posts and apply as appropriate.  Depending on how the recruitments process unfolds, you may be considered for either position depending on skillset and once the make-up of our entire team becomes more evident.

We are seeking exceptional candidates with a PhD in Chemistry, Physical Chemistry or a related discipline. Expertise in one or more of surface chemistry, immobilisation of biological molecules, fluorescence spectroscopy, organic chemistry, biophysics, and peptide/protein handling would be a distinct advantage, and applicants with multiple of these skillsets are encouraged to apply.  We are keen to receive applications from ambitious, and energetic individuals with an interest in translating laboratory-based research into real-world applications.
