About Your Next Job
Ready to shape the future of Pharma? At Johnson & Johnson in Leiden, we are bringing breakthrough innovations to global health. We are looking for a driven Master's student to dive into the world of process modelling using Computational Fluid Dynamics (CFD). Want to work on state-of-the-art gene and cell therapies for 40 hours a week starting September 2026? Keep reading!
About Your Next Colleagues
During this 6-month internship, you will step into our Drug Product Development and Delivery department. You will develop computational tissue models to simulate local drug delivery for future protein, gene, and cell therapies. By using imaging data and tissue properties like stiffness and porosity, you will map out how drugs distribute and retain in targeted areas. Working alongside experienced scientists, your predictive models will help optimize clinical injection procedures and guide future formulations.
About Your Tasks and Responsibilities
- Conduct high-level simulations using CFD tools to optimize biomedical processes and systems.
- Collaborate with global cross-functional teams to interpret and align simulation results with business objectives.
- Evaluate tissue models under varying injection parameters to overcome drug delivery barriers.
- Gather insights into how advanced engineering applications drive healthcare innovations.
- Manage daily project tasks independently while contributing actively to your immediate teamwork setting.
About Your Skills and Experience
Are you an analytical thinker who loves solving complex technical puzzles? We are looking for a proactive and enthusiastic student who thrives both independently and in a dynamic team setting.
- You are a Master’s student pursuing Mechanical Engineering, Chemical Engineering, or a related discipline.
- You have a strong command of the English language both verbal and written.
- You have experience with ANSYS CFD packages, including CAD.
- You have experience with Python or MATLAB.
- You have analytical problem-solving skills.
