Contributing to deviation management, CAPA processes, change control, and continuous improvement initiatives

Safety & Organizational Responsibilities

Safety and data integrity are essential in this role.

You will:

Adhere strictly to biosafety, chemical safety, and waste management procedures

Work according to aseptic techniques within controlled laboratory environments

Train and mentor colleagues, students, and interns in validated assay execution and documentation practices

Ensure data integrity, traceability, and reproducibility in line with GLP and internal quality standards

Your Profile

We are looking for a hands-on technician with strong cell culture expertise who enjoys working in a regulated and innovative R&D environment.

Education:
HBO / BSc degree in: Biomedical Sciences, Biotechnology, Cell Biology, Bioengineering or a related field

Experience
1–3 years of industry experience with cell culture assays
Experience in regulated environments, preferably within R&D

Language
Professional level of English (written and spoken)

Skills & Competencies

The ideal candidate brings a combination of technical expertise, precision, and a collaborative mindset.

Strong hands-on experience with cell culture techniques

Familiarity with assay validation principles (e.g., robustness, reproducibility, controlled variability)
