Today, Lonza is a global leader in life sciences operating across three 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.

This position is part of a team that develops novel technology that supports Lonza’s allogeneic cell therapy manufacturing, such as 3D bioreactors, downstream processing of cells and/or exosomes, advanced analytical methods, etc. This is a hands on research job (75% lab based) where the scientist will be responsible for defining project targets, designing and executing experiments, analyzing data and drawing conclusions/next steps.

Key responsibilities:

  • Generating project targets based on the vision communicated by higher management, and designing experiments to achieve those targets.
  • Independently analyzing experimental data using statistics and graphing software, and communicating the findings to project team and executive committee level stakeholders.
  • Analysis includes drawing conclusions within the wider group and department context, hypothesizing mechanistic explanations of observed results, and proposing next steps.
  • Generating/updating timelines in MS Project.
  • Communicating findings on various levels, including: directly to manager, team updates, R&D group updates as well as interdisciplinary company forums and external meetings.
  • Writing and revising technical documents, maintaining accurate and up to date records, including appropriate lab notebook recordings, lab SOPs, test protocols and reports.
  • Management of potential academic collaborations to support exploratory feasibility studies.
  • Training new hires, interns, and collaborators (both internal and external) on the bioreactor platform.
  • Perform administrative tasks or other duties as needed.

Key requirements:

  • 5 - 7 years of experience in Biology as an independent researcher.
  • Master’s in Biology, bio or chemical engineering, biotechnology.
  • PhD in Biology, bio or chemical engineering, biotechnology.

Knowledge Required:

  • Cell/Molecular biology and basic biochemistry
  • Fundamentals of human cell culture and molecular biology
  • Strongly preferred:
  • Understanding of cell therapy and therapeutic exosomes (cell types, diseases targeted)
  • Expertise in technologies for the isolation and characterization of extracellular vesicles, including exosomes.
  • Data analysis/statistics


  • Background in bioprocess engineering, especially bioreactors and downstream techniques
  • Developmental biology/regenerative medicine
  • Closed processing systems

Skills Required:

  • Aseptic technique / work with BSC level 2
  • Human cell culture and isolation
  • Excellent oral/written/presentation communication skills; strong work ethic; delegating skills; ability to perform in a team setting

Strongly preferred:

  • Exosome isolation and analysis
  • FACS
  • qPCR, digital PCR
  • NTA, Nano FCM or similar for nanoparticle characterization
  • Bioreactor operation
  • Design of Experiment


  • Bioprocess scale-up
  • Assay development (detection assays, functional assays)
  • Automation (liquid handlers, robots, control systems)
  • Continuous processing (e.g. separation)
