Senior Scientist Translational Developability in Stevenage

We are currently seeking an enthusiastic, dynamic and self‑motivated senior scientist to join the Translational Developability group within MDE and working within a matrix role. The role will be primarily lab focused, working with teams of scientists with diverse skills including protein biochemists, in vitro and ex vivo assay scientists, antibody pharmacologists and molecular biologists as well as in close partnership with other parts of the GSK organisation. It involves using high throughput methods to rapidly profile large panels of antibodies and perform interpretations on the generated data in the early discovery phase. These activities will focus on in vitro prediction of antibody characteristics during exposure in vivo.

Large Molecule Research within GSK is a department dedicated to the discovery of novel and effective biopharmaceutical medicines. This department comprises several complementary functions focused on the progression of a portfolio of biopharmaceuticals from initial antibody discovery, expression and characterisation to molecular engineering and biological and physiochemical profiling. Within the Large Molecule Discovery Unit, the Molecular Design and Engineering (MDE) group takes accountability for antibody engineering and developability profiling prior to candidate selection to continuously improve molecule quality and transform discovered leads into potential therapeutics.

As a Senior Scientist, you will lead laboratory science to characterise and de‑risk therapeutic antibody and biopharmaceutical candidates. You will work closely with colleagues in discovery and early development to design and run experiments that deliver clear decision‑making data. This role offers hands‑on laboratory work, scientific ownership, and opportunities to develop both technical and leadership capabilities while contributing to the progression of innovative therapies.

We create a place where people can grow, be their best, be safe, and feel welcome, valued and included.
