At Julius Clinical, we wake up every day with the same goal in mind: helping life-changing drugs reach the market faster by developing and conducting clinical drug trials in the best possible way. Therefore, together we work hard, challenge each other on the ‘way it has always been done’, and look for creative ways to improve our work continuously. Thinking out of the box and taking ownership is not only allowed, but encouraged.


Who we are

With around 200 employees, Julius Clinical is a medium-sized company. We are small enough for you to know where the management team will spend their summer vacation and large enough to provide you with a solid career path and ample development opportunities. Some of our employees are acknowledged experts in their field of scientific or medical expertise, most have business acumen, and all are dedicated to improving healthcare.

Our roots

Julius Clinical was founded in 2008 as a spin-off from the University Medical Centre (UMC) Utrecht in The Netherlands. The entrepreneurial mindset that led to the foundation of our company still characterizes the way we operate on a day-to-day basis. As a result of our academic and medical roots, science is at the heart of everything we do. We take great pride in our partnerships with several world-renowned key opinion leaders.

What we do

Julius clinical is a unique mixture of a contract research organisation (CRO) and a site management organisation (SMO). We partner with leading biopharmaceutical companies and academic investigators around the globe to perform cutting-edge clinical trials. This type of demanding research requires more than a one-size-fits-all approach. Through our unique fusion of scientific leadership and operational excellence, we take a creative, credible, and smart approach to research. We share risks and responsibilities with our partners and have the flexibility to respond effectively to the ongoing challenges of innovative clinical trials.

What we offer

Happy clients start with happy employees. Our people are our main capital, and we put great effort into providing a place to work where people feel motivated and comfortable. Your development is always at the top of our agenda. Our headquarters are located in a beautiful monumental building in Zeist, The Netherlands, which is easily accessible by car and public transportation. Because of our dynamic and cooperative, collegial company culture, we encourage an open-door policy. We also provide you with great coffee, and regularly organize fun activities. We welcome people from a wide variety of nationalities and professional backgrounds.
