Scientist – Cell Biology

The Role

Semarion is a dynamic, early-stage spin-out company with a technology platform at the cutting edge of interdisciplinary innovation. We are building a cell biology team focused on application development for the SemaCyte® platform. This will span work around our three main application areas – adherent assay-ready cells, cell-line multiplexing, and primary cell assay miniaturization. The primary focus of this team is the validation of our platform across a range of drug screening assays with an emphasis on oncology. We are looking for a driven scientist to be an early member of our cell biology team to drive the validation of our technology platform. Good foundational understanding of the drug screening process along with cell-based assay experience will be required. We envision this role growing in scope and responsibility as Semarion evolves.

April 1st 2022 (flexible)


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

About Semarion

Semarion operates at the edge of the physical and life sciences by using microchip industry materials and techniques to transform cell-based research. The rate of data output during drug discovery work is often limited by the adherent nature of cell models. Our solution is simple: keep colonies of cells attached to a surface, but now bring this surface into suspension. We make this possible with our SemaCyte® cell assaying microcarrier platform. These materials are ultra-miniaturized, steerable wells which turn adherent cells into liquid reagents. With our SemaCytes we can accelerate, miniaturize, and multiplex cell assays to drive 10x gains in drug screening applications such as SAR studies, cell panel screening, or patient-derived cell work. Our platform can seamlessly integrate with existing workflows, while also enabling novel assay methodologies. Our mission is to revolutionize in vitro research on cell models to help create better medicines, faster.

We were founded in Cambridge, UK in 2018 by Jeroen Verheyen (CEO and a clinical neuroscientist), Tarun Vemulkar (CTO and an applied physicist), and Prof. Russell Cowburn (NED and Professor of Experimental Physics). Semarion secured a £250k pre-seed investment in 2020 with the Cambridge based healthcare accelerator StartCodon and has closed a seed round of funding in December 2021 of £2.14M. Post successful alpha trials of our technology platform in 2021 we are now expanding our operational team. We are in an exciting phase of product and application development with a focus on creating our first market ready product in 24 months.
