Head of Reagent Development, LEX Diagnostics Limited, GB

We’re developing diagnostics at the speed of life. Want to lead the team building the reagents that make it possible?

At LEX Diagnostics, we’re pioneering ultra-fast PCR at the point of care bringing lab standard performance to GPs, emergency departments, and field settings with the LEX VELO platform. Our Biology team is at the heart of that innovation, and we’re looking for a Head of Reagent Development to lead the charge on all things lyo.

This is a role for someone who’s hands on, technically excellent, and thrives in a leadership position. Someone with deep experience developing and scaling qPCR/RT-qPCR reagents, and a real track record in lyophilisation. If you know your way around freeze drying cycles, enzyme stability, and you’re motivated to turn that into something with real global impact, we’d love to hear from you.

What you’ll be doing

As Head of Reagent Development, you’ll be responsible for the design, optimisation, validation, and transfer to manufacture of our LEX VELO reagent systems, both wet and lyophilised. You’ll lead and grow a team of experienced molecular biologists and biochemists and work closely with production, assay development and engineering teams to ensure reagents are not just effective, but fully integrated with our platform.

You'll balance hands on lab work with project management, team mentorship, and strategic input into our wider product development. And you’ll do all this in a fast moving, ISO13485-aware environment, working with real purpose toward a high impact product launch.
