The Opportunity
We are seeking an experienced scientist to join the Research Bioassay group, part of the Lead Discovery & ProteinEngineering(LDPE)department at CSL’s Melbourne research facility. This group specializes in developing and implementing biochemical and cell-based assays for the screening of potential therapeutic candidates. The successful applicant will report to the Senior Manager of the Research Bioassay group.
In this role, you will support a variety of projects by performing in vitro biochemical and cell-based assays to measure the potency of protein-based therapeutic candidates. You will be responsible for evaluating, developing, and conducting bioassays crucial for selecting therapeutic lead candidates. Additionally, this position may involve conductingin vitroexperimentswithin other groups, such as Antibody Technologies andProtein Engineering and Expression, within the Lead Discovery & Protein Expression department as needed. You will collaborate closely with a small team of research scientists and contribute to a broader, multidisciplinary team across various areas within CSL.
