Are you the kind of scientist who notices the details others miss? Good, we've got just the role for you.
At LEX Diagnostics, we're on a mission to make diagnostics faster, simpler, and more accessible, without compromising performance. Our LEX VELO point-of-care PCR system is built to bring lab-quality results wherever they're needed. And behind every accurate test result is a set of reagents that have passed the highest standards of quality control.
That's where you come in.
We're looking for a Quality Control Scientist to join our Reagent Production team and take on a hands-on role assessing the consistency and quality of our reagents, from raw materials to final products. You'll be running RT-qPCR assays, troubleshooting issues, collaborating across teams, and documenting results in a way that makes regulators smile.
If you're comfortable in the lab, curious about how things work (or don't), and excited to play a key role in getting a new IVD to market, we'd love to talk.
What You'll Be Doing
- Running QC tests on incoming materials, in-process reagents, and finished products using qPCR and RT-qPCR
- Following established protocols and documenting results with clarity and accuracy
- Working closely with the Biology, Manufacturing and Quality teams to ensure every batch meets our gold-standard
- Supporting continuous improvement efforts and helping refine QC methods as the product scales
- Ensuring everything is done to Good Laboratory Practice and aligned with our ISO13485/FDA-aware processes
- Contributing to the reliability and reproducibility of one of the fastest PCR systems in the world
