RA/SRA Downstream

We are seeking a Research Associate or Senior Research Associate with 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.


  • Maintain downstream process lab.
  • Keep track of inventory records of supplies, materials, and prepare requisitions as necessary.
  • Determine expression titer by ELISA and other techniques.
  • Perform protein and antibody purification by chromatography and filtration technology.
  • Characterize protein and antibody targets using typical analytical methods in protein chemistry.
  • Document results in laboratory notebooks.
  • Share data with management and team members.
  • Research literature to identify alternative methodologies and solve scientific problems, establish, and qualify assays.
  • Prepare technical reports, summaries of testing, and detailed protocols.
  • Learn new techniques as the job requires.


  • BS/BA degree in Biology, Biochemistry, or chemical engineering background or related fields with three (3) or more years of experience in biopharma industry, preferably in a fast-paced startup environment.
