Our Bioassay Division is expanding, and we have an exciting growth opportunity for a MSc-level Scientist. The position will start as a one year contract, with the possibility of becoming a permanent position.

Custom Biologics is a Health Canada audited, GMP-compliant, global service provider for functional testing of biotherapeutics, biosimilars and antibody drug conjugates. For over 17 years our scientists have been designing and validating sophisticated bioanalytical assays to characterize and measure the therapeutic potential of large and small molecule biotherapeutics. Our work supports regulatory drug submission applications from biopharmaceutical companies globally.

We are seeking a Scientist with expertise in protein biochemistry, cellular biology and molecular biology. Strong troubleshooting skills and QPCR experience is highly preferred. The successful candidate will be a key technical contributor to the design, validation and execution of cell-based and solid phase ligand binding assays to measure the functional and affinity binding properties of biotherapeutics including therapeutic monoclonal antibodies, biosimilars, antibody drug conjugates, peptides, biologics and oncolytic viruses.

This position requires hands-on laboratory work, as well as supervision of research associates and technicians. Familiarity with GMP/GLP regulations is desired but not a required.

Scientific excellence is the pillar of the Company. The ideal candidate will be joining a team of highly motivated individuals and a workplace culture driven by collaboration, achievement, quality and growth. S/he is highly motivated with a strong ‘can-do’ personality, excellent laboratory, critical thinking, results driven, and works well within a team to deliver excellence to our clients.
