About Biofidelity

Biofidelity’s mission is to improve and extend patients’ lives by enabling better targeting of therapies, early detection of treatment resistance, and routine monitoring of treatment response. Our unique technology has been designed to allow rapid, broad adoption of our assays in testing labs around the world, enabling a step change in patient care. 


Biofidelity has developed a revolutionary molecular diagnostic assay, enabling the rapid, ultra-sensitive detection of DNA targets with a transformational simplification of workflows.

Using just four steps and standard laboratory instrumentation, our assays can detect as little as a single molecule of mutated DNA against the background of billions of healthy molecules present in a typical patient sample, enabling straightforward detection of clinically actionable genetic markers at the earliest possible stage.


Biofidelity is expanding its R&D team responsible for the development and optimisation of its core technology. Working alongside the assay development team, the role will include:

  • Development of novel molecular techniques and tools for high sensitivity molecular diagnostics
  • Characterisation and optimisation of molecular assays
  • Design of complex multiplexed reactions


With a creative and ambitious mindset, you should have a PhD or equivalent industrial experience in molecular biology, with substantial experience in the development of molecular techniques and tools, along with a demonstrated ability to apply your knowledge and expertise to complex challenges. The ideal candidate would have experience in at least some of the following areas:

  • High-sensitivity molecular assay development
  • Multiplexed PCR/qPCR
  • DNA/RNA extraction and sample preparation
  • Isothermal amplification techniques

We offer the chance to join a rapidly growing team working on meaningful technologies with the potential for substantial real-world impact, coupled with an excellent working environment, a competitive salary, and a comprehensive benefits package including private medical cover, company share option scheme and 26 days holiday allowance.
