Downstream Scientist/Sr. Scientist

We are seeking a Scientist or Senior Scientist with significant experience in process development particularly in the context of antibody and antibody-like biologics. The ideal candidate will have a solid background in protein purification and bioanalytical techniques used to characterize biologics. This is a key position in the Process Sciences and Manufacturing group and will have the opportunity to collaborate across groups to contribute to multiple fast-moving drug discovery projects.


  • Operate and maintain instrumentation for the analysis and purification of antibodies.
  • Develop and perform protein and antibody purification by chromatography and filtration technology.
  • Tech transfer purification processes to internal and/or external manufacturing groups.
  • Characterize protein and antibody targets using typical analytical methods (SDS-PAGE, SEC, endotoxin, etc.).
  • Keep accurate and current records of research and/or project related activities in laboratory notebooks.
  • Prepare technical reports, summaries of testing, and detailed protocols.
  • Share data with management and team members.
  • Research literature to identify novel methodologies and solve scientific problems and apply to the overall program.
  • Publish research in peer-reviewed journals and present work at scientific conferences when possible.
  • May supervise one or more direct reports and proactively engage in their development.


  • Ph.D. degree biology, biochemistry, chemical engineering or related fields with at least two (2) years of experience or Bachelor/Master’s with more than five (5) years of post-degree experience in the biopharma industry, preferably in a fast-paced startup environment.
  • Extensive experience in protein purification using a variety of chromatographic techniques with hands-on experience using and maintaining AKTA FPLC (AVANT, Pure, Ready) systems with Unicorn software.
  • Prior experience interacting with CROs/CMOs for manufacturing and characterizing biologics.
  • Experience with viral and tangential flow filtration.
  • Demonstrated experience with analytics and characterization of proteins and antibodies (SDS-PAGE, Western Blot, residual Host Cell Proteins, residual DNA, HPLC).
  • Ability to evaluate purification processes for scalability, cost and quality and then transfer to CMO.
  • Experience with designing and performing DOE is a plus.
  • Good understanding of biophysical techniques such as DSF, DSC, DLS, IEF is preferred.
  • Ability to work independently or with limited direct supervision.
  • Excellent organization, interpersonal, and communication skills and ability to clearly and effectively present data at group and company meetings
  • Consummate team player and respectful of others is a must.
