PSI CRO
Hiring · 260 open jobsGeneral information
PSI CRO is a contract research organization. It runs clinical trials for other companies, mainly Phase 2 and Phase 3 trials in oncology, hematology, gastroenterology, autoimmune disease, and neurology. Alongside the trials themselves, it offers clinical monitoring, regulatory affairs support, data management, biostatistics, and medical writing to help clients run studies and prepare for approval. PSI CRO is based in Zug, Switzerland.
The company was founded in 1995. It describes itself as the only fully independent, privately owned mid-sized CRO operating in over 50 countries, with about 3,000 employees across 56 countries today. That independence matters: it is a global-scale company that has stayed privately owned rather than becoming part of a larger group.
Currently, there's a total of 233 job openings at PSI CRO. Over the last 30 days, 282 jobs were added and 228 were removed (job postings usually stay up ~10 days before being removed).1
