For our team in Leiden, we are looking for an Operator with experience or clear affinity in bioprocessing within a GMP-regulated environment. In this role, you will contribute to the production of advanced therapeutics and support the scale-up of new products toward clinical and commercial readiness.

This position is broader than a purely hands-on manufacturing role. In addition to executing operational activities in the cleanroom, you will also contribute to GMP documentation, process-related investigations, and continuous improvement initiatives. This makes the role suitable for candidates who combine practical bioprocessing knowledge with the ability to understand and support the quality and documentation side of GMP-manufacturing.

You will work in a cleanroom environment under GMP guidelines, and your responsibilities may include:

• Executing upstream processing activities, including bioreactor assembly, fermentation and process monitoring;
• Executing downstream processing activities, such as filtration and chromatography;
• Supporting fill line activities where applicable;
• Performing in-process checks and ensuring production steps are executed according to procedures and specifications;
• Reviewing and completing GMP documentation, including batch records, logbooks and data entry;
• Supporting or handling deviations, non-conformances, change controls and CAPAs;
• Updating or improving work instructions and SOPs;
• Contributing to deviation investigation reports and other GMP-related documentation;
• Participating in process improvements, operational excellence initiatives and cross-functional projects;
• Supporting 5S and general cleanroom compliance activities.

• MLO, HLO or BSc/MSc degree in Biotechnology, Biochemistry, Life Sciences or another relevant scientific field;
• Hands-on exposure to upstream and/or downstream processing through work experience, internships, traineeships or relevant lab/practical education;
• Basic understanding of bioprocessing concepts such as USP, DSP, bioreactors, fermentation, filtration or chromatography;
• Understanding of GMP and the importance of accurate documentation in a regulated production environment;
• Ability to work both practically on the floor and analytically on documentation, investigations and procedural improvements;
• Strong attention to detail and a structured way of working;
• Comfortable working in a dynamic environment with changing priorities and varied responsibilities;
• Able to work independently, while also collaborating effectively within a team;
• Fluent in English, both spoken and written.

Working at PSS means working in a team where people support each other, take responsibility for their work and stay closely connected to the client environment they work in. You will be part of an international setting, with colleagues who value clear communication, teamwork and a good working atmosphere.

We believe it is important that people can keep developing in their role. That is why we offer specialist training and opportunities to build your knowledge and skills further. We also make time to stay connected as a team, for example through monthly team lunches, team activities and moments where colleagues are recognized for their contribution. We offer:

• A responsible position within the team;
• Room to share your ideas and input;
• Specialist training and opportunities for personal and professional development;
• 31 vacation days per year based on a full-time employment contract, with the option to purchase 5 additional days;
• The option to use gross/net benefit schemes for sports and the purchase of a bicycle;
• Access to an online preventive mental health platform;
• A flexible start time between 07:00 and 09:00, depending on team planning and operational needs;
• A suitable salary and additional benefits.

Working at PSS gives you the personal approach of a medium-sized organization, with the wider network and structure of Eurofins as a parent company. In your work, you regularly interact with other companies and scientists within the Eurofins group, which brings variety to the role.

This also means there may be opportunities to grow, depending on your role, experience and development.
