Scientist – Cell Biology


Start Date: May-June 2023 (flexible)

Salary: We offer a competitive compensation package including share options, subject to experience

The Role
Semarion is a dynamic, early-stage spin-out company interfacing advanced microchip materials with cellular disease models to create a cutting-edge cell-based assay platform. We are expanding our cell biology team which focusses on the development of applications of our SemaCyte® microcarrier platform. Specifically, this involves human cell culture and the development and evaluation of cell-based assays for drug discovery in the areas of oncology, neuroscience, and toxicology.

We are searching for someone who is excited to join a small but rapidly growing team of cross-disciplinary researchers. A good foundational understanding of the drug screening process along with cell culture and cell-based assay experience is required. We envision this role growing in scope and responsibility as Semarion evolves.

About Semarion
Semarion is a seed-stage spin-out from Cambridge University with a mission to accelerate the pace of drug discovery. We are revolutionising adherent cell screening to produce better drug data, faster. Our proprietary SemaCyte® microcarrier platform leverages novel materials physics to introduce flexibility, miniaturisation, and multiplexing into existing drug discovery workflows. By deploying techniques from the microchip industry, we create magnetically steerable cell carrier systems which can move small colonies of adherent cells for accelerated drug discovery and completely novel research paradigms. The company is focussed both on direct sales of its microcarriers and bespoke application development with biopharma partners. For more information, visit

• Thrive on feedback: understand that receiving feedback well and providing it constructively is a vital part of building a team that makes progress

The background we are looking for
• Degree in cell biology, biological science, pharmaceutical science, life science or equivalent industrial experience
• Over 2 years of experience with cell culture
• Significant experience with cell-based assays
• Good understanding of the drug discovery process
• Experience in one of the following areas would be an advantage: fluorescence cell imaging, plate-reader based cell assays, high content imaging, reporter cell lines, primary cell culture, stem cell culture and differentiation.
