Job description

Yacht Life Sciences has a vacancy for a Senior Operator to work for Janssen Vaccines / Johnson & Johnson (Leiden, the Netherlands), within Drug substance operation (DSO).

Drug Substance Operations (DSO) has a GMP manufacturing facility at the Bioscience park in Leiden where we proudly produce groundbreaking medicines against diseases that have a global impact, such as vaccines against HIV, RSV and Ebola. This is also the place where we produced the COVID-19 vaccine material that was developed in-house by Janssen Vaccines and Prevention.

DSO is the department where Clinical trial material (CTM) is produced for new cutting edge vaccines that are in clinical testing Phases 1 to 3. There are two main production sites. The DSO production process is at pilot scale (50L) and is executed by two main teams. Upstream processing is performed by the I-team and downstream processing by the D-team. Each team consists of eight persons, led by a Supervisor. In this department, a position is available for a Senior Operator that will be trained to perform the production of the first batches of COVID-19 vaccine.
