Proclinical is currently recruiting for a Biologist II, Protein Purification with a pharmaceutical company located in Worcester, MA. The candidate will be involved with all aspects of protein purification and protein chemistry to support biopharmaceutical process development. Responsibilities, under the supervision of a Senior Scientist.

Job Responsibilities:

• Perform routine bioanalytical sample preparation, assay execution to support pre-clinical PK and PK/PD studies
• Assist to prepare samples from tissues, cells and biofluids for proteomics studies via LC-MS
• Operate, maintain and troubleshoot one or more LC-mass spectrometers (e.g., Thermo QExactive-series, Thermo Lumos-series, triple quadrupole, Triple-TOF) and HPLC systems for peptide separation and analysis is preferred
• Prepare detailed documents describing procedures and results
• Develop economical, robust steps for recovering the target protein from bioreactor harvests using chromatography, filtration, and other separation techniques; developing downstream purification processes to be transferred to Manufacturing; and performing laboratory scale process characterization studies; can perform basic data acquisition and analysis, documenting in electric lab notebooks
• Perform various bioanalytical assays, including HPLC, ELISAs and SDS-PAGE, to aid in rapid process development
• As appropriate, the candidate may supply technical support for pilot and/or GMP manufacturing of clinical materials

Skills and Requirements:

• BS, MS or PhD degree in analytical science, chemistry, biochemistry, biophysics, biology, or related technical discipline with typically 1+ (MS), or 0+ (PhD) years of relevant experience. Experience in biotech/pharmaceutical industry setting or academic core lab is preferred
