Assay Development Scientist

Who we are

We are a VC and government backed healthtech start-up at the vanguard of predictive diagnostics to make medicine more proactive. Our first product is a novel infectiousness test for COVID-19. From a saliva sample, it identifies on-the-spot whether the user has an active infection in 15 minutes. The Vatic KnowNow SARS-CoV-2 Rapid Test is driven by the globally unique, proprietary detection mechanism underpinning the test which mimics the surface of the human cell, acting like a trapdoor for the virus. This test is the first infectiousness test developed utilising the lateral flow platform. We are very lucky that we already have a special group of people and we are looking for someone who also values the social impact of what they do.

Job overview

We are looking for highly motivated and passionate individuals to join our company as an assay development scientist. This role will involve driving the research and development programme, involving projects in the COVID-19 space, inflammation/immunology and other infectious diseases. You will be reporting to the CTO and Senior Research Scientist and the main focus of the role will be to carry out benchtop research to validate existing assays as well as contribute to the development of new ones, write up publications and support with clinical product evaluations.


  • Developing and exploring novel assays in our portfolio.
  • Implement and utilise a range of methods, assays techniques in assay development.
  • Analysis of biomolecules via physicochemical methods, binding affinity or kinetic assays.
  • Troubleshooting and monitoring technical performance issues via QC.
  • Review literature, write papers and protocols and SOPs to conduct research.
  • Assist project teams to identify, evaluate and adapt new technologies when appropriate.
  • Working and communicating effectively with different teams by providing reports and presentations at meetings through keen analysis of data.
