Location:

Cambridge, United Kingdom

Lonza is looking for a motivated early-career Scientist to join our R&D department at our Cambridge facility. In this role, you will lead client-facing projects involving the design, execution, and optimisation of in vitro cell-based bioassays using human peripheral blood mononuclear cells (PBMCs) to assess the immune response to therapeutics.

What you will get

• Work in an engaging and collaborative laboratory environment.
• Expand your skills across human primary immune cell biology and bioassay platform development.
• Gain practical experience with human primary immune cell isolation, cutting‑edge cell-based assays, and advanced immunogenicity screening techniques.
• Lead and contribute to real-world client projects, playing a direct role in evaluating and advancing therapeutic candidates.

What you will do

• Support and deliver in vitro cell-based bioassays to assess immune responses to therapeutic candidates across multiple client studies.
• Perform routine isolation, banking, and characterisation of human peripheral blood mononuclear cells (PBMCs) following standard operational procedures.
• Maintain reliable laboratory workflows, troubleshoot routine experimental procedures, and assist in optimising and expanding assay capabilities.
• Keep accurate laboratory records, compile findings into technical reports, and present results to project teams and clients.

What we are looking for:

• Degree (BSc or MSc) in Biological Sciences, Immunology, or a related discipline.
• Solid understanding of immunology and bioassay principles.
• Practical laboratory experience with aseptic cell culture, immune cell isolation, or assessment of immune responses, gained through university research projects, placements, internships, or industry experience.
