Reagent Development Scientist, LEX Diagnostics Limited, GB

At LEX Diagnostics, we’re reinventing PCR for the real world. Our point-of-care system, LEX VELO, delivers ultra-fast molecular diagnostics, and your reagents are at the heart of it.

We’re looking for a Reagent Development Scientist to help develop temperature-stable, lyophilised reagents that perform under pressure, literally and figuratively. You’ll be helping us push PCR beyond the lab and into hospitals, clinics, and emergency settings around the world.

This is a hands on role, perfect for a scientist who thrives in the lab, enjoys complex problem solving, and wants to help build next generation diagnostics in a fast paced, collaborative environment.

What you’ll be doing

This isn’t just lab work, it’s working side by side with biologists, engineers, and production teams to ensure our reagents are robust, reliable, and ready for the real world. You’ll:

• Design and optimise qPCR and RT-qPCR reagents, with a focus on lyophilised and temperature-stable formulations
• Work closely with Integration, Engineering, and Assay teams to ensure reagents perform consistently within the LEX system
• Contribute to the development of new tests and features as our platform evolves
• Collaborate with our Reagent Production and Manufacturing teams to scale up and validate formulations
• Support experimental design, execution, data analysis, and documentation
• Work within an IVD framework, contributing to documentation under ISO13485 and preparing reagents for regulatory compliance
• Help troubleshoot and iterate with flexibility, accuracy, and a team mindset
