Position Summary

The candidate will play a lead role in Protein Sciences, with responsibilities to include the supervision of protein purification and analytical characterization for both small and large scale antibody and antigen production. Both within the Protein Sciences research group and within interdisciplinary project groups, the candidate will provide technical and scientific oversight to solve challenging problems, speed project timelines and potentially reduce needed resources. The incumbent will coordinate protein expression, purification, and analytics activities and will supervise the day-to-day and long-term goals and activities of three or more staff.

Essential Functions
  • Play a leadership role in the expression, purification and analytical characterization of recombinant proteins.
  • Responsibilities of Protein Sciences group:
  • Design and generate therapeutic antibodies, antigens, and secondary reagents.
  • Develop and implement methods for purification and deep biochemical and biophysical characterization of therapeutic candidates and key reagents, and develop methods for identifying candidate antibodies with potential to be formulated at high concentration.
  • Transient and stable protein expression in mammalian cells.
  • FPLC purification of proteins and reagents.
  • HPLC analysis of purified recombinant proteins and peptides.
  • Protein quantification and characterization assays (SDS PAGE, IEF, etc.)
  • Non-specific labeling of proteins.
  • Analytical analysis of protein thermal stability using thermofluor/lightcycler and DSC technologies.
  • Provide technical oversight and leadership in the purification and in-house development activities for antibody lead candidates including formulation and preclinical activities.
  • Participate in multi-departmental research and development projects and discussions, providing scientific leadership and direction regarding activities related to Protein Sciences.
  • Act as in-house expert in matters related to protein chemistry and purification instrumentation, technical, or scientific areas (e.g., HPLC, FPLC, DSC, etc.).
  • Pro-actively assist others within Protein Sciences in solving technical problems.
  • Partner with Development and Manufacturing to ensure seamless transition and continued support, when necessary, of therapeutic candidates.
  • Coordinate experiments with colleagues to ensure rapid achievement of objectives and overall goals.
  • Manage the day-to-day and long-term activities, objectives and performance of staff.
