Working at ClarusONE
Two Fortune 500 companies. Two nations. Diverse, dedicated and knowledgeable teams. It all comes together to create a unique and dynamic culture - in a place where you'll feel welcome and valued.
ClarusONE was originally established by a team of US expatriates who relocated to setup our London office back in 2016. Over the years we have grown considerably and hired local talent, continuing to build a diverse and varied workforce. Our team brings skills and experience from a diverse range of backgrounds and industries, allowing us to build on our capabilities for the future.
We challenge ourselves and support each other to meet ambitious targets, with the ultimate goal of enabling access to affordable medicines.
