PhD degree in a scientific discipline with a minimum of 6 years of experience in the Biopharmaceutical industry developing and optimizing functional bioassays and immunoassays in support of therapeutic protein potency and characterization preferred. Or Bachelor's degree in a scientific discipline with at least 14 years work experience or Master's degree with at least 12 years work experience Preferred.

Position Description:

The Biologics Development group at Celgene has an exciting opportunity for an experienced bioassay scientist to join our team. It carries responsibility for establishing and implementing phase-appropriate impurity methods to support in-process sample testing, release, stability, and biological characterization of Celgene's portfolio of biological therapeutics. The candidate will be involved in helping to establish a new function as well as closely collaborate with internal early discovery groups, process sciences groups, and external partners.

Responsibilities will include, but are not limited to, the following:
  • Design, develop, optimize, phase-appropriately validate, and transfer impurity methods to internal and external QC testing labs
  • Support internal development of Celgene therapeutics by providing impurity assay support for Host Cell Protein (HCP) immunoassays and qPCR (CHO DNA) for process development, GLP Tox, and GMP release.
  • Contribute to new strategies for HCP assays, including evaluating and implementing novel approaches for impurity detection.
  • Manage the transfer and ensure oversight of analytical methods to external CMOs/CROs.
  • Contribute to the establishment of an internal impurity assay testing group to support in-house process development and GMP release.
  • Evaluate and implement new technologies and instrumentation to support operational efficiency and improved sample throughput.
