Senior Scientist – mRNA Process Development (Downstream)

Today, Lonza is a global leader in life sciences operating across five continents. While we work in science, there’s no magic formula to how we do it. Our greatest scientific solution is talented people working together, devising ideas that help businesses to help people. In exchange, we let our people own their careers. Their ideas, big and small, genuinely improve the world. And that’s the kind of work we want to be part of.

Based in Geleen, you will take a leading role in mRNA downstream process development, owning complex purification challenges from experimental design through data interpretation. You will work with a high level of independence, while collaborating closely with multidisciplinary teams to develop robust, scalable and manufacturable mRNA processes for our clients.

• A senior scientific role with a high level of ownership and autonomy.
• The opportunity to shape and improve downstream mRNA purification processes.
• Collaboration with experts across Process Development, MSAT and Analytical Development.
• A dynamic environment where scientific depth, initiative and problem-solving are valued.

What you will do

• Provide scientific and technical leadership for downstream mRNA process development activities.
• Independently design, execute and interpret complex purification experiments.
• Lead problem-solving activities and translate data into clear process improvements.
• Develop and optimize purification strategies using chromatography and filtration technologies.
• Write and review high-quality scientific reports and technical documentation.
• Support technology transfer activities and ensure processes are scalable and manufacturable.
• Collaborate with internal teams and engage with customers on downstream-related topics.

What we are looking for

• Bachelor’s, Master’s or PhD degree in biotechnology, bioengineering, chemical engineering or a related field.
• Strong hands-on experience in downstream process development for mRNA or large biomolecules.
• Advanced expertise in purification techniques such as chromatography (affinity, ion exchange, HIC, SEC) and filtration technologies, including TFF.
