Careers – LEX Diagnostics

LEX Diagnostics is a diverse and energetic team of people motivated to redefine point-of-care diagnostics. To that end, we are laser-focussed to launch our first product: an ultra fast PCR test.

Our team and the culture we embody are our greatest assets. Our decisions are driven by customer needs, not technological interest. Our people believe in compromising their technical area for the greater good of the product. Working at a startup has its own specific challenges; we display resilience and grit, and approach challenges with a sense of urgency. We recognise and celebrate success as a team because we all contribute to technical areas that are not always our own.

If you are passionate about changing healthcare, tackling difficult technical challenges and working with a collaborative team, please see our active roles below or contact us with a CV and Cover Letter.
