Current Employment Opportunities at Sphere Fluidics


Job Title: Research Scientist in Physics and Engineering – (Knowledge Transfer Partnership Associate in Microfluidic Instrument Development)

  • Location of job: Cambridge / Edinburgh (approx. 90/10)
  • Functional area: Physics & Engineering, Sphere Fluidics
  • Category: Research
  • Salary range: £30,000–£36,000 per annum
  • Start date: We are looking someone keen to start this exciting project who can take up the position no later than the 22nd May.

This Knowledge Transfer Partnership is a joint project between Sphere Fluidics Limited (SFL), Cambridge, UK and Heriot Watt University (HWU) in Edinburgh, UK, to transfer and embed research from the university into the company. For this two-year project the candidate will initially join Graeme Whyte’s research group at the Institute for Biological Chemistry, Biophysics and Bioengineering at Heriot-Watt University, for your initial introduction and training for the project (~3 months). Within Graeme’s lab at HWU, you will have access to state-of-the-art microfabrication, microscopy and microfluidic technology, and be fully supported with world-leading expertise in those fields. This project will build on Graeme’s experience in image-based closed-loop feedback for highly monodisperse picodroplet production. The associate will then be based full time for the remainder of the project at Sphere Fluidics Limited, which is located near Cambridge.

Sphere Fluidics Limited is an established, Life Sciences company (formed in 2010) developing single cell analysis systems for high-throughput screening in biologics discovery and development. It has a global presence and is currently selling its microfluidic and single cell encapsulation technologies via consumables, research instruments and integrated industrial microfluidic based platforms. The customer base includes biopharma, biotech, synthetic biology and academic users. The novel microfluidic tools, allows complex processes to be miniaturised, scanning millions of single cells or molecules and isolating rare, valuable ’hits’. SFL currently has 34 employees and has over 300 international customers.

The successful candidate will work as part of a multidisciplinary team (engineering, software, chemistry and biology) to design and build a new instrument platform for semi-automated picodroplet production, this initial platform will lead on to several new commercial products. The successful applicant will learn new skills through a generous training and development budget and will be encouraged to attend and present their work at suitable international conferences.


A ‘Knowledge Transfer Partnership’ is funded by the InnovateUK with 17 other funding organisations and enables companies of any size to access additional scientific, engineering or management knowledge and expertise from universities and research organisations and to import new techniques and technologies into their businesses. This project is for the development of a new intelligent platform for a range of picodroplet techniques to allow scientists to discover rare cell phenotypes and to help to solve a range of biological questions ranging from antibody discovery to antimicrobial resistance, enzyme evolution and synthetic biology.

This position will integrate new academic approaches to picodroplet production as a platform technology for the life sciences sector, scaling down cell-based assays, in the picolitre range, to enable high-throughput screening for the discovery of rare phenotypes. This flexible instrument will demystify picodroplet generation and make this technology available to biologists and technologists with little or no microfluidics experience in a cost-efficient manner. This Picodroplet cell encapsulation system (PISCES) project will incorporate many new features not currently available commercially. The KTP associate will be supported by the teams at both SFL and HWU.

Using bespoke, micron-scale fluidic devices and high-speed microscopy imaging, you will develop an instrument for productization that enables highly monodisperse picodroplet production. Other uses of this platform are envisaged as the company further improves the flexibility of its instrumentation to address a wide range of biological high throughput screening applications.

The project, with the support of both HWU and SFL, will bring together aspects of microfluidic and optical design, software, electronics, technology development and product design engineering to develop a new class of instrument for cell-based picodroplet discovery. With such a diverse skill set collectively available this position offers a great opportunity for the associate to build up many new skills across a range of cutting-edge fields.

Main Duties and Responsibilities

  • Develop new microfluidic devices and technologies to productize monodisperse picodroplet production.
  • Collaborate with appropriate team members on understanding the biological requirements that the instrument needs to be able to address, both now and in the future in relation to competitive market forces.
  • Work closely with collaborators at Heriot Watt University to translate the research developments in to an alpha-prototype instrument and identify new challenges.
  • Understand the current software and engineering strategies within SFL and help develop these initiatives into a new commercial instrument.
  • Be keen to undertake appropriate training courses both given and self-taught with the appropriate support of all partnership team members.
  • Develop the research objectives towards more sophisticated instruments based on the PISCES instrument.
  • Maintain written records of research results and progress generated intellectual property and data analysis.
  • Analyse and interpret the results of own research and generate original ideas based on outcomes.
  • Build internal contacts and participate in internal networks for the exchange of information and learning both at SFL and HWU.
  • Disseminate results of research at conferences, peer reviewed journals, and/or other appropriate media.
