Scientist X-ray Crystallography at ZoBio in Leiden (NL)

ZoBio ( was founded in 2004 and is located in Leiden, Netherlands. We offer innovative research services in the field of small-molecule drug discovery to the pharmaceutical and biotech industries. Our international team of 27 people covers four fields of expertise: Protein Engineering and Production, Assay Development and Screening, Structural Biology and Medicinal Chemistry.

We are currently looking to strengthen our team with an X-ray crystallographer with a track record in protein crystallography and a strong background in the X-ray crystallographic data analysis. In particular, experience in building and refinement of protein – small-molecule complexes would be extremely helpful.

The successful applicant will support our clients’ drug discovery programs by solving ligand-protein structures. You will work with minimal supervision but in a highly collaborative environment within the Structural Biology team and will effectively cooperate on a per-project basis with other research groups at ZoBio. This role requires working on multiple projects simultaneously and in a rapidly evolving environment. Team spirit and excellent organization and communication skills are essential.


  • High-throughput crystallographic screening utilizing automation and robotics.
  • High-throughput and -quality structure elucidation and interpretation of biological macromolecules in complexes with small molecules of interest.
  • Utilization of X-ray crystallography pipelines with the aid of computational structural biology tools to aid the efficient structure elucidation of protein-ligand complexes.
  • Report results to the Head of Crystallography and prepare presentations on the structural data for the project teams and clients.
  • Maintain up-to-date understanding of the state-of-the-field in X-ray crystallography in relation to modern drug discovery challenges.


·        PhD in relevant field with experience in an industrial or collaborative setting.  

·        Hands-on experience with ligand modelling into electron density maps and macromolecular model building and refinement in the context of Structure-Based Drug Discovery campaigns.

·        Hands-on experience in solving challenging X-ray crystallography cases (e.g. ab initio structure solution).

·        Experience with computational structural biology tools like ligand docking, virtual screening, molecular dynamics simulation would be considered as an advantage.

·        Experience in scripting and programming would be considered as an advantage.

·        Able to work in a team in a result-driven, goal-oriented environment.

It is fully expected that you will become a permanent and integral member of the ZoBio team, after an initial period of 12 months. Applicants at either the Senior Scientist or Scientist level will be considered. 

A tailored remuneration package will be proposed in line with individual qualifications and experience. The position is immediately available; the evaluation and assessment of candidates will run until the position is filled but not later than November 1st 2020.
